WinUAE 2.4.2 Betas

Beta 1:

Quote:

- Autovsync 50/60Hz also accepts 100/120Hz modes if available, supports also refresh rates +-1 from nominal.
- CD32: CD command receive DMA emulation correctly emulated, TOC read hack removed.
- CD32: Repeat each CD TOC packet 3 times (same as real CD TOC format) (Universe title screen CDA)
- CD32: CD audio stopped if multiple play requests were sent very quickly (Universe in-game CDA)
- GUI RTG monitor selection implemented.
- Low latency vsync + fastest possible CPU auto adjustment updates.
- Legacy vsync automatic adjustment implemented, hopefully improves stability. (Remember that legacy vsync is only compatible with approximate/ce CPU modes)
- FPS led background flashes yellow if frame was missed in vsync modes.
- Detect display driver forced vsync, switch to double buffered mode if low latency no buffer mode.
- Always call D3D SetMaximumFrameLatency(1) if vsync mode (any vsync) to reduce latency, previously was only called when low latency no buffer mode used. (SetMaximumFrameLatency only available on Vista and later) Usually display driver control panel can be also used to override this value.
- Added auto scale integer scaling method, uses autoscale display size instead of max overscan.
- Integer scale mode filter horizontal and vertical zoom sliders value is now added to native screen size before calculating integer scaling value. (Negative values reduce size of screen = scale to higher multiplier earlier)
- Integer scaling supports non-power of 2 integer upscaling ratios now, downscaling still only supports 1/2, 1/4 and so on to prevent scaling artifacts or blurriness.
- Warp mode now works properly in all vsync modes.
- Most filter modes (autoscale etc..) now fill "invisible" borders with black, for example this removes ugly extra border(s) in autoscale fullscreen or full-window mode when using non-4:3 displays. (In other words anything outside of 4:3 sized window are now blanked in non-4:3 screen/window sizes)
- Low latency vsync displayed blank screen if emulation was restarted using GUI Restart button.
- JIT GUI cache size box was broken.
- Do not return error code if uaehf.device read or write io command has null data pointer and length is also zero.
- Added more Windows error codes to directory filesystem to AmigaDOS error conversion table.

- Filter system partial rewrite again. Do not use static display buffer. Always dynamically reallocate internal buffer if display mode changes (double scan modes, A2024 etc..). Fixes slowdown introduced in 2.4, also fixes shader filters that expect texture size = output size. Very tall (>1024 line) programmed modes are also now fully visible. Most likely some more updates needed..
- Always cancel custom event autofire if any release event arrives.

WinUAE 2.4.2 Beta 3:

Quote:

- FPS led was always yellow in most non low latency vsync modes.
- Custom input event toggle didn´t work (3rd and 4th slots), (2.4.1)
- Custom input event non-toggle mode with qualifiers didn´t work correctly.
- Allow D3D RTG hardware sprite if non-power of 2 textures are supported, do not require shader support.
- Do not override currently selected CD image when loading statefile if new CD path does not exist.
- Do not report CD not present state if restoring CD32 statefile that was created with inserted CD. It would usually cause immediate reboot to CD32 title screen and most CD32 shovelware ports won´t care about the CD after game has been loaded. This has been broken previously many times..
- Any active breakpoint stopped all interrupts in some situations if 68020 cycle-exact mode.
- "ALT-TAB or middle mouse button untraps mouse - F12 opens settings" window title was missing.
- Uncapture mouse when entering debugger.
- Fixed blank screen in directdraw + no filter mode. (b1)
- Do not move directories or empty files to Windows recycle bin (if recycle bin option enabled).

---

WinUAE 2.4.2 Beta 4:

Quote:

---

- Custom input event autofire wasn´t always canceled when shortcut included qualifier(s).
- Do not crash if 7zip unpacking fails because out of memory or process address space. (Big compressed CD images and 32-bit Windows)
- Log also RDB dostype in text format.
- Replaced misc panel checkboxes with scrolling checkbox list view. Now there is unlimited space for all kinds of on/off options that I previously refused to add because of lack of GUI space.
- Added disable notification icon option.
- Loading statefile using GUI now remembers statefile filename, allowing to save configuration files with statefile (running configuration file will automatically load the statefile). This required manual config file editing previously. Statefile path and checkbox that "forgets" stored path added to GUI.
- Ignore vendor specific USB usage pages (Do not list for example some Logitech USB mouse/keyboard receiver dongles)
- Z2 RTG + 68EC020 fixed, RTG requires memory mapping. (Memory mapping was originally JIT only and 68EC020 is not JIT compatible)

---

WinUAE 2.4.2 Beta 5:

Quote:

---

- More custom input event fixes.
- Replaced custom event single line string dialog with larger multiline dialog, increased allowed custom event string length.
- Autoresolution didn´t detect interlaced mode in some situations.
- Added "Internal events" input device category. Currently it only contains two events: "CPU reset" and "Keyboard reset". It can be used to customize what happens when emulated Amiga is reset. For example: set CPU mode back to fastest possible, eject or insert disks, quit emulator, etc..
- Added 68020 prefetch CPU core. Emulates instruction prefetch without cycle-exact. "More compatible" option enables this mode (Previously it did nothing in 68020 mode)
- A1200/CD32 Quickstart compatibility slider changed: cycle-exact/prefetch/fastest possible without JIT/JIT
- ASPI support removed.

---

WinUAE 2.4.2 Beta 6:

Quote:

---

- PC raw MFM decoding improved (uaeunp, Amiga/ST/PC multiformat PC images didn´t decode properly)
- Interlace flag wasn´t set if resolution had "i" flag but refresh rate didn´t, caused blank screen in D3D modes.
- Set system time to host time (timer.device/TR_SETSYSTIME) when exiting GUI or unpausing if syncronize clock option is enabled. Only works if at least one directory filesystem is in use. (Shares directory filesystem process to minimize resource usage)
- Interlaced host resolution field matching with emulated interlace rewritten, now simply waits extra field if fields don´t match. Can cause small sound glitches if small buffer but this is also much more reliable than old method. (Need tweaking)
- Small non-fastest CPU mode low latency vsync tweaks.
- Ignore CPU writes to DSKDAT. (Useless "DSKDAT: FIFO overflow!" log messages caused by some programs that poke DSKDAT).
- Added -nodirectinput command line parameter that completely disables directinput device enumeration.
- Gayle PCMCIA CF IDE emulation improvements, PCMCIA CF config #2 also supported (PC primary IDE IO addresses)
- GUI position is also saved in fullscreen mode, separate from windowed mode GUI coordinates.
- Some chipset mode on the fly configuration changes also reset RTG internal variables, causing blank screen when returning back to RTG mode. (Very old bug, "SetSwitch() - Picasso96 0x0x0" in log)
- Fullscreen RTG mode refresh rate uses chipset mode refresh rate or rate directly set in Expansions panel. Automatically selects lower available refresh rate if selected rate is unsupported.
- Added option to enable/disable RTG vblank interrupt emulation. Previously it was automatically enabled if Refresh rate option wasn´t set to disabled. Moved to separate GUI option because of above new feature and because some games don´t like RTG board generated interrupts.
- Direct3D mode RTG OSD only updated when any part of RTG bitmap changed.
- Blank unused displays(s) (opens full screen topmost black window(s)) option added to misc panel.
- Only save minimal CPU context (registers and PC) during native/m68k code switching. Previously it saved lots of unneeded data, including data that can be changed outside of CPU emulator. May also increase performance in some situations. Finally explanation and fix for mysterious copper state corruption.
- CD image mounter: MDS image CD audio tracks didn´t play if subchannel data was not included, MDS image data tracks that also included subchannel data returned wrong data.
- Host MMU write protect ROM regions in JIT direct mode because JIT only checks destination address type when generating x86 code for the first time. Badly crashing programs can corrupt loaded ROM image causing repeating red/black screen reset loop. (Another mysterious previously reported problem solved)
- Restructured UAE boot ROM variable locations, ROM part write protected.
- Doubleclicking Input panel Input Source column resets clicked line back to default. (Currently keyboards only)
- Added uae-configuration harddrive attribute modification support:
-- Syntax: uaehfX_Z where X = unit number, Z = attribute name. (for example: "uaehf0_bootpri 10")
-- Attribute names: devicename, volumename, root, bootpri, read-only, filesys, controller.
-- Syntax is write-only. Use plain uaehfX to check current values.
-- Reset required to activate modified settings.

WinUAE 2.4.2 Beta 7:

Quote:

Directory filesystem 64-bit seek (ACTION_CHANGE_FILE_POSITION64) broke in 240b27
-nodirectinput mode was always enabled. (b6)
-nodirectinput does not anymore disable mouse/keyboard directinput enumeration if rawinput fails to initialize.
Syncronize clock enabled and loading new config crashed in some situations (b6)
Blitter emulation didn´t leave correct data in blitter´s B data register after linedraw finished, fixes No Way demo by Academy that seems to use wrong minterm that requires correct static value in B data register.
WASAPI exclusive software volume control support. It seems normal WASAPI volume control does nothing in exclusive mode.
Added support for unimplemented integer instructions to 68k emulation code generators. Not yet in use. (This is easy part, unimplemented floating point support is very difficult because it requires special FPU stack frame)


Experimental memory space rewrite. Now WinUAE reserves address space as much as possible (~1.6G if 64-bit OS, 512M if 32-bit, note that this is only reserved space, actual memory is not yet allocated). Allows more stable on the fly memory size changes. It is not guaranteed that this is safe to use and won´t cause side-effects or other bad behavior or loss of performance, please test and report.

---

WinUAE 2.4.2 Beta 8:

Quote:

---

- 68060 and CPU compatible checkbox ticked: generate unimplemented instruction exceptions instead of emulating instructions that real 68060 don´t have. Integer instructions only, 040/060 FPU emulation still supports all 6888x instructions.
- Set FPU FPIAR register (No one shouldn´t care, except unimplemented FPU exception handler which isn´t supported)
- RTG state restore broke in previous update.
- Save RTG mode palette to statefile (Quite important missing information if dislay mode is 8-bit..)
- More memory space reservation updates.
- "Restart" GUI option improved, shouldn´t cause strange errors if new config has 32-bit RAM enabled and old one didn´t.
- Savestates with 32-bit RAM configured should now load without need to first load configuration that has same amount (or more) RAM configured.

---

WinUAE 2.4.2 Beta 9:

Quote:

---

- Replaced readpu.c 68020+ special case TST An/PC-rel and CMP #imm,PC-rel variants with proper table68k entries.
- Debugger disassembler decodes illegal instructions if opcode is supported by higher CPU model, shown in parenthesis, note that PC is only incremented by 2 in this situation.
- Debugger W (write to memory) command supports multiple values and strings.
- Slow debugger commands can be aborted by pressing return (console only)
- 64-bit DIVL.L checked div by zero exception before checking if instruction is 68060 compatible.
- Use IOCTL_STORAGE_QUERY_PROPERTY to query optical drive vendor/product/version information instead of SCSI inquiry.
- "Take screenshots before filtering" supported in RTG modes, takes screenshot from emulated VRAM buffer. 8-bit png if 8-bit RTG mode, 24-bit png if >8 bit RTG mode. Does not capture mouse if mouse is emulated hardware sprite.
- "Capture before filtering" recording option supported in RTG modes.
- D3D D3DERR_DEVICELOST handling improved.
- Inhibit Windows error dialogs completely. On some systems missing harddrive still opened annoying Windows no disk error dialog(s).
- Improved extended ROM statefile support.
- Save ROM overlay state to statefile separately from CIA OVL pin state, fixes loading of statefiles if current configuration has CIA overlay support but state configuration does not. (Gayle based chipset or CD32)
- Misc statefile load compatibility improvements when current config is very different compared to statefile´s configuration.
- DMA debugger ´c´ = copper wanted this cycle but it wasn´t available
- Extremely rare BPLxDAT non-DMA modifications emulated while bitplane DMA is disabled, not perfect but at least screen isn´t completely blank anymore.
- Ancient Superfrog copper hack removed, it isn´t needed anymore. (EyeQlazer/Scoopex is nearly correct now)

WinUAE 2.4.2 Beta 11:

Quote:

---

- END special qualifier didn´t work when combined with other qualifiers, some END + shortcuts leaked key presses to emulated Amiga side (b10)
- GUI wasn´t centered and/or scrolling if single monitor, full screen mode and resolution smaller than 640x480. (b6) Automatically center to screen if GUI title bar isn´t visible on any monitor. Two or more monitors and >800x600 resolution desktop in any monitor = always allow manual GUI positioning.
- Wait for Blitter changes:
* - Does nothing in 68000 cycle-exact mode.
* - Approximate CPU speed or 68020 CE: Pause CPU if blitter would steal all CPU cycles
* - Fastest possible: Any kind of active blit pauses CPU if writing to any blitter register.
* - Logged if triggered (only first 10 times)
- Quickstart modes (except 68000 CE) enables Wait for Blitter option.
- Wait for Blitter GUI only sets above "automatic" mode, manual config file editing supports forced "always" and "only if not idle" modes. (for debugging purposes)
- RTG video capturing uses now RTG vsync timing, not (possibly very different) custom chipset vsync timing.
- Added UAE Boot ROM AOS "heart beat" vblank interrupt, do not sync clock or check filesystem insertions if heart beat counter does not change = OS has been taken over, prevents possible memory corruption if program also overwrote system structures.
- RTC year tens digit was not in correct BCD format, probably no program cared about the difference. (Bug since the beginning)
- Extended adf writing was disabled, forgotten debugging and it was also disabled in 2.4.1. Oops. (241b11)
- POTGO register state was not fully reset when loading state, disabled mouse right/middle button in some situations. (for example Sound of Silents)
- AUDxDAT manual audio mode and new period was written to AUDxPER: new period value was loaded too late, after first 8-bit sample was finished.
- AUDxVOL is 7-bit register (64-127 = max volume, 128 = 0, 129 = 1 and so on..). Actual volume range is 0-64.
- Sinc interpolator updated from UADE (from few years ago, better late than never..)
- Debugger ´m´ command didn´t show last byte of memory region.
- Log COPJMPx while copper is waiting blitter cycle conflict. Does not yet emulate blitter pointer = COPxLC copy.

---

The changes are really starting to get technical now. To the point I'm not fully understanding them. :lol:

Just shows how the actual emulators functionality is really mature and it is now mostly just perfecting it to get the maximum amount of software to run.

Beta 12:

Quote:

---

- Moved cycle-exact option to Chipset group in GUI. Other options are minor options/hacks, CE is not.
- Do not enable wait for blit if immediate blitter is enabled in quickstart mode.
- Added RTG hardware sprite (mouse cursor) enable/disable option. Enabled by default if D3D mode. Was always enabled previously if D3D mode.
- GUI Memory panel 32-bit RAM size information text incorrectly included Z2 mode RTG memory.
- Added directory harddrive limit option to Harddrives panel. When enabled, all directory harddrives size is faked to ~950M with free space relative to original size (for example 500G HD with 100G free = 950M HD with 950*100/500=190M free) This hack is workaround for installers that think drive is full or have negative free space if drive is larger than 2G (32-bit overflow). Can be changed on the fly. Edit configuration file manually if you want custom limit size. Also virtual fake block size changed from 1024 to 512. More compatible with KS1.x dos commands that seem to use hardcoded 512 block sizes when calculating disk size.
- cpu_throttle configuration entry also accepts decimal values.
- Added Start minimized and Start mouse uncaptured Misc panel options.
- In minimized mode D3D/DirectDraw display updates are also now completely stopped.
- ECS Denise/AGA border blanking handling rewritten again. (Brian the Lion borders are black again)
- Ignore color 0 (background) writes if borderblank is currently enabled when deciding autoscale start vertical coordinate. (Brian the Lion)
- Parallel port audio sampler emulation partially rewritten, it actually sounds correct now, mono/stereo option added. AudioMaster IV confirmed working. Very pointless feature.

---

Beta 13:

Quote:

---

- Parallel port audio sampler had very bad quality on some systems. NOTE: Sampler requires exact DirectSound recording position reporting = not that good results when using some onboard Realteks etc.. (It can be made better but because this is really pointless feature: pay or buy a better PC)
- Very old statefiles triggered keyboard powerup initialization sequence when restored, caused phantom keypresses.
- Sinc audio interpolation filter clipping fixed. (Was always wrong in UAE, was much more noticeable after b11 audio update)
- Input configuration parser didn´t parse custom input event strings correctly if it contained ´.´ or ´,´ characters.
- Added experimental (and mostly useless) option that removes DOS reserved name restriction (CON is the most popular because it is also included with WB disks). Note that this causes some interesting side effects: most Windows programs, including Explorer, won´t be able to open any file if it has DOS reserved name... You don´t need this option, UAE has always mangled illegal names transparently (for example CON becomes something like "__uae__con" on host side) Configuration file only: win32.filesystem_mangle_reserved_names=false (defaults to true if not set)
- Disable screensaver option didn´t work, SetThreadExecutionState() needs to be called periodically, not just once, function documentation is a bit confusing..
- When deciding first visible line and programmed mode: select which is largest, VBSTOP or VSSTOP. (SuperPlus)
- Added Keep autoscale aspect ratio checkbox, only sort of working now...
- Map rom region size mirrors ROM size, address automatically moved to 0xe00000 (512k) or 0xa80000 (1M) if 24-bit CPU.
- Remove interlace artifacts option halved size of display horizontally in some programmed screen modes.
- Portaudio sound and sound was deactivated automatically: sound led kept showing buffer underrun state.
- Disable screen updates if monitor enters power saving mode.
- When restoring state file with floppy image(s) missing (files moved etc..), there still was rare possibility that floppy drive was reported as empty.
- Some more manual BPLxDAT emulation updates, Sequential Magnet part garbage introduced in previous update is gone.
- Color registers were emulated as non-existing instead of write-only in OCS/ECS modes. (I guess only visible difference will be more colorful display if program crashes or does weird things and starts reading from color registers..)
- DENISEID is now non-existing if 68000 prefetch or cycle-exact and OCS Denise. (Programs may misdetect if no prefetch emulated, and now programs, if they even exist, that misdetect it on real OCS A500 will misdetect it on emulation too! )
- Renamed Paths panel "WinUAE defaults"-paths, meaning of selection should make more sense now.
- Better input qualifier GUI, Windows key default qualifier added.
- Slot #5-#8 custom events didn´t work correctly.

And finally:

- GUI resize and font selection support added (misc panel). It was possible after all, needed only some hacking..
- * Default size is now larger then previously.
- * This is a hack, rebuilds classic Windows dialog resources on the fly while adjusting GUI element coordinates and size.
- * GUI size after resizing may not be exactly what you expected.
- * Windows always closes and reopens after resize. It is also normal, can be improved, later if ever..
- * Window/Fullwindow/Fullscreen have separate position, size and font settings.
- * Less than 80% size not officially supported, overlapping and clipping is normal. Select smaller font.
- * Possible future improvements: more preset sizes, some kind of autofit in smaller fullscreen modes.
- * I hope GUI now appears to be more modern than it actually is

- Version bumped to 2.5.0.

- Borderblank emulation rewritten yet again, now borderblank state is included with color 0 change events (this time exactly where it should be), fully cycle-exact, works even if some strange program toggles it multiple time / scanline.
- Some GUI sanity checks, for example check if GUI size is really small or huge before opening GUI window and also after GUI is open. Reset size and fonts to default if size is out of range.
- GUI Windows DPI setting compensation fixed.
- Activate COPJMP bug emulation, only if 68000 CE. (logged since b11)
- Autoscale aspect ratio fixed. Setting is enabled by default now.
- Disable map rom if 24-bit address space and 2M ROM (No space for ROM mirror).

EDIT: GUI size is incorrect if Windows DPI is not 100%. Bug in full release build compiler options, only winuae.zip alphas worked..

---

Beta 15:

Quote:

---

- Fixed too large GUI size if non-100% Windows DPI setting and full optimized build. (b13)
- Fonts with long names caused corrupted dialog structure.
- Marked WinUAE as Windows Vista/7/8 compatible. This should have been done long time ago, without this Windows enables some backwards compatibility features, for example Aero gets disabled in fullscreen directdraw.
- Disabled COPJMP bug emulation, it triggers incorrectly in Seven Sins/Scoopex. (Already did some logic analyzer testing but I can´t yet confirm exact trigger conditions for this bug, it wasn´t as simple as I originally thought)
- Editing non-custom event´s qualifier reset input target to none.
- Lightpen cursor wasn´t removed when lightpen mode was disabled.
- Wintab tablet messages corrupted memory if Windows driver installed but tablet mode was not enabled. (b6)

---

Beta 16:

Quote:

---

- Added easy to use log options to Paths panel. Open = open selected log or current config to text editor. Save All = create file that includes both logs and current configuration. Makes requesting logs easier for debugging purposes. Log checkbox overrides misc panel logging option. Checkbox state not saved, resets back to non ticked after restarting. (Included config is exact current configuration, not necessary same as last loaded config file)
- Fixed uae-configuration config listing garbage ????? line at the end.
- USB HID game controller [-] and [+] input axis movement used wrong event (one-shot instead of normal press/release).
- Possible fix for D3D display alignment errors in some modes (AMD only apparently)
- Fixed D3D blank screen after alt-tabbing back to fullscreen mode. Non-D3DEx (Windows XP mainly) only.
- Non UAE HD controller harddrives and CDFS config data conflict, inserting CD corrupted HDF path.
- Some CD (both images and physical drives) on the fly media switching problems fixed.
- Ignore start uncaptured and start minimized if starting in fullscreen mode.
- Input panel slots #2-#8 not saved to config file if slot #1 had GamePorts [PORTx] event.
- Configuration #1-#3 selected and GamePorts not set to and then changed back to , original slot #1 event was not restored.
- CD32 gameport type also enabled normal joystick firebutton/2nd button event. Only CD32 red and blue are needed.
- Break to debugger if program jumps to non-existing memory ("Did something stupid") and any break point is already active.
- Remember last selected Input panel device.
- 64-bit build now support up to 2.5G memory space and max 2G of Z3 fast RAM, emulated as 2x1G Z3 boards (1G is max Z3 board size) Note that AmigaOS may have signed integer problems if 2G border is crossed.

- Enabled windowed mode window maximize button.
- Removed windowed mode window inner edge.
- -diskswapper command line looks inside all supported archive files.
- Any non-UAE controller harddrive didn´t work. (b16)
- Beta 16 D3D alignment fix updated, previous broke 1:1 pixel mapping in some situations. (Test this again!)

---

Beta 18:

Quote:

---

- FPS and CPU% react quicker now. Can Show previously hidden CPU usage spikes. NOTE: CPU% now showing "myserious" usage spikes does not mean emulation has become slower!
- Automatically limit tablet mode X and Y coordinate range to prevent 16-bit signed overflows if tablet has large resolution. (not confirmed)
- Always generate full size mask texture, workaround for mask pixel mapping errors in some scaling modes.
- Only release pressed keys if window or screen gets reopened (prevents stuck keys), not when any graphics related config option changes.
- Do not allow GUI resize if GUI is larger than fullscreen resolution because Windows may automatically resize it to fit on screen, making GUI completely unusable.
- Always recalculate Display panel horiz/vert centering option internal values when configuration changes.
- 68030+ CPU and more compatible checkbox checked: enable very basic prefetch emulation, only 68000-68020 have more complex prefetch emulation.
- JIT + more compatible also enables basic prefetch. Only works if code is not yet translated. (Not much point but it was easy to do)
- Added route all MIDI In data to MIDI Out configuration option.
- Improved 68030 MMU instruction decoding. WHDLoad + MMU option enabled + 68030 CPU does not crash anymore. (No, there still is no 68030 MMU emulation, it is only emulating 68EC030 without MMU circuitry which probably does not exist in real world + hack for A3000 1.4 ROM)
- Few (rare) variants of MOVES didn´t increase PC correctly.
- BSR.L was emulated as 68020+ instruction on 68000/010. (BCC.L was correct)
- For some reason 68000 BSR.B and BSR.W address exception stack frame PC field points to new odd PC, instead of address of BSR opcode.

Beta 19:

- GamePorts panel Test function now shows all currently mapped input target(s). Can be used to test any kind of input event mapping.
- Do not map 3rd button to joystick/pad with more than 2 buttons if GamePorts panel gameport mode is joystick. Joystick is meant to be max 2-button, non-pullup resistor game controller.
- Directory filesystem ACTION_DISK_INFO InfoData->id_Inuse is now non-zero if any files or locks are open. (Was previously always zero)
- Use D3D (if available) to fetch GPU names listed in monitor selection GUI. Should now show correct GPU name when running on hybrid GPU systems.
- GUI CD audio volume control added.
- Standard PAL/NTSC mode horizontal position (without filters or centering enabled) is not slightly shifted anymore, not sure when this changed, probably in some update that improved programmed mode display positioning.

Beta 20:

Quote:

- Reduced Gayle based configuration CIA memory bank size to 4096 bytes, only accesses to bfdxxx and bfexxx goes to CIA chips if Gayle.
- Reverted b19 horizontal change, I forgot that it was made to fit max overscan modes better.. (Manually adding "gfx_horizontal_tweak=8" to config file can be used as a workaround, if needed for some reason)
- RTC update in b11 was not compatible with KS 1.x.
- improved RF5C01A RTC emulation, previously KS2.0+ detected stopped clock and attempted to reset it (which is no-op because emulated clock´s time is currently read-only) and after reset it finally read the time.
- RTC year value is saved differently depending on OS version, Pre-2.0: RTC year value = current year - 1900, 2.0+: year value = last 2 digits. Both methods supported when reading. WinUAE now uses pre-2.0 method if MSM clock chip (because this is the only type that KS1.x supports), 2.0+ if RF clock chip, previously always used -1900 method.
- RTC 12/24h bit emulated, this is not used by AOS.
- RTC time/date, alarm and memory data save/load to file supported (alarm time/date, note that alarm interrupt pin is not connected in Amigas, and 104 bits of memory, used mainly for A3000 SCSI settings, included with RF clock chip type). Date/time ignored when loading.
- added win32.gui_active_page=name, sets default GUI panel after emulation has been started (Old win32.gui_page = before emulation starts)
- In some situations adv. chipset may have used incompatible data stored in config file even if compatible settings was ticked.
- Syncronize clock on the fly CIA TOD adjustment is now only active if heartbeat signal (b11) is detected.
- b11 heartbeat system was not fully disabled when UAE boot rom was unavailable.
- On screen led HD/CD/NVRAM indicator is blank if device is not available (like floppies already did).

Beta 21 & 22:

Quote:

---

Beta 22:

- "Generic" Amiga model incorrectly enabled A3000 DMAC emulation which caused most programs that require UAE Boot ROM in normal 0xF00000 area to crash. (Old bug, b20 adv.chipset caused it to appear much more commonly)
- Disable ROM protection when switching JIT off on the fly.
- Dragging standard HDF to Hardfiles panel sets correct default geometry.
- Added logical cylinder value to HDF config data, default is zero = calculate from size of the HDF (same as previously)
- Added "physical" CHS values to HDF config data, can be used to override autogenerared IDE emulation CHS values. (append ",logical cyls,C/H/S" to hardfile2 config entry. No GUI support.)
- GUI resize button was permanently disabled after it was unticked once.
- log_disabled=1 in registry (DWORD) or ini disables winuaebootlog.txt.
- Check DPI value when selecting default GUI size.
- CD32 audio emulation update, Guardian CD32 (and possible some others) had muted audio since b1. Immediate reply to CD play command should not have "play active" bit set. It should be only set in later status packets.

Beta 21:

- Use software volume also in WASAPI non-exclusive because WASAPI main volume control also affects waveOut used by CD audio. (XP + DS also seems to affect waveout.. CDA really should use some more modern sound API, later...)
- Floppy sound sample mixing volume fix, volume level got lower if more than one drive had enabled sounds.
- Virtual mouse driver option IECLASS_POINTERPOS inputevent ie_Qualifier apparently needs to include mouse button state bits or Magellan II´s (AmiKit) menus won´t stay open, possibly affects other programs too. (This is not documented in HRMs, hmm...). "Start menu" still won´t work but it is application bug because it also won´t work if mouse is moved using Amiga + cursor keys.
- CDFS crash fix when unsupported media (not unreadable but for example UDF-only DVD) was accessed.
- Check and ignore possible duplicated CDFS CD insert or eject Windows message.
- Compile time directory filesystem logging is now runtime option (-filesyslog and -filesyslog2)
- Borderblank still didn´t work correctly in all situations. (Aladdin AGA)
- Fullscreen DirectDraw mode IDirectDrawSurface7_Flip "Was still drawing" fix. (I still have no idea what was I thinking of..)
- Added "waiting blits" special case, when blitter is started and blit would use all available cycles: start waiting for the blit immediately.
- Changing hardfile path does not anymore clear device name and filesystem text boxes.
- Fixed crash when loading statefile with JIT enabled (b6 "ROM protection" should be disabled temporarily when loading UAE boot rom data..)
- zlib updated to 1.2.7
- Built-in AROS ROM updated.

Beta 23 & 24:

Beta 24:

- CDFS: ACTION_DISK_INFO no disk status really works now.
- Fixed "Windows mouse" sometimes hitting invisible barriers in windowed mode if window size changed and mouse was captured. (Quite old bug)
- blitter_cycle_exact=true and cpu_cycle_exact=false confused blitter emulation if BLTSIZE was written twice while DMA was disabled.
- CAS and CAS2 instruction fixes from Aranym (I guess these are practically never used on Amiga..)
- Ignore duplicate USB HID axis IDs. (I was lazy and only added duplicate button check previously..)
- USB HID D-Pad/POV axis may have caused ghost events.
- GamePorts panel Remap separated axis configuration support (for example up can be mapped to button and down can be normal down axis), and multiple input sources can be mapped to single input target. Selection cursor now wraps around to allow multiconfiguration.

Beta 23:

- CDFS: Joliet CDs didn´t work and caused crashes. Directory listing worked but it was only possible to open non-existing files
- CDFS: ACTION_DISK_INFO never returned no disk status.
- Filesystem path selection and default RDB settings broke in b22.
- FPU FINTRZ didn´t work correctly if input value was outside of signed 32-bit range. (Bug since the beginning?)

Beta 25 (RC1) (Final in end of November. Really.):

Quote:

- Switching to interlaced mode and autoscale enabled: don´t calculate new size until 2 frames have been drawn to prevent multiple display size changes.
- More accurate GUI resizing algorithm.
- Show also first few bytes of disk in harddrive selection GUI.
- Add real harddrive as IDE: calculate physical CHS values using H=16,S=63,C=total blocks/(H*S) formula to better match with real hardware. (ROM built-in IDE drivers use IDE identify device CHS values to calculate last accessible block of drive, LBA support was added in ROM updates)
- Action Replay 2 copper list detection code hang tweak.
- Prowizard AC1D update (Asle)

Beta 26 RC2: (1-2 weeks to go)

Quote:

- RTG aspect ratio setting was loaded to wrong variable from config file (filter panel aspect ratio, not RTG)
- CD32 CD audio play delay timing fixed. (Was originally timed using bad Liberation CD image)
- RTG on screen leds was rendered twice in D3D mode (D3D sprite and software method).
- Audio 14bit to 16bit scaling introduced extra low level noise.
- Only enable AUDxPER limit hack (to reduce CPU usage with weird programs) if audio DMA is active. Manual AUDxDAT audio software may use higher periods.
- Fixed rare crash in input/gameports panel test/remap support.
- Added on screen leds per-led enable/disable config file support, for example show_leds_enabled/show_leds_enabled_rtg=power,df0,df1. In future versions order of led names are also supported and gaps in place of disabled leds will be gone.
- DPI GUI size compensation disappeared (b25).

Beta 27 RC3:

- Modulated volume value wasn´t range checked, caused noise if volume word was not between 0 to 63. (Platou title music)
- Fixed SPTI mode CDFS crash.
- CDFS didn´t correctly remove hidden trailing ;1´s in some Joliet CD filenames.
- SPTI standard CD access: Use READ (10), not READ CD when requesting standard 2048 byte user sectors, not all BD/DVD drives support READ CD when reading DVDs.

Beta 28 RC4: (Final on 2-3 days unless something really bad happens)

- uaescsi.device SCSI sense data is now returned correctly (For example MakeCD shows error messages that make sense now)
- AHI channel swap also swaps AHI recording channels.
- BMP screenshots were corrupted.
