New ports of UAE are normally quite basic in there setup. Remember that UAE has only ever been an OCS emulator and has no support for AGA. This was added directly into WinUAE by its developer and not migrated back to UAE. This is something that will always hold back Amiga emulation on any other platform, since WinUAE broke away from the original UAE project and went it alone to accelerate development and do a lot more with it. UAE is still however the basis for most other system Amiga emulators, so it will stay more basic. I'm imagining the PS3 emulation is about similar to the Wii Amiga emulator. Obviously a lot more power available to the emulator on the PS3.
