Hi and welcome.

The error code you are getting is a general memory error. It just means the Amiga has encountered a problem and can't continue.

What games are you trying to run?

The A600 uses the ECS (Enhanced Chip Set) and as you mentioned a version of Kickstart 2. Many older games were written for the older A500 which had the OCS (Original Chip Set) and Kickstart 1.2 or 1.3.

The A500 also came with 512KB of Chip ram and the A600 came with 1MB chip ram. With the A500 when the ram was expanded to 1MB the extra 512MB of ram was fast ram. With the A600 the extra ram expansions normally added an extra 1MB of chip ram.

The difference in the ram is the most common reason you will get the A600 crashing with that error message. Many game developers on the A500 ignored the developer notes from Commodore and instead wrote their games bypassing the OS and making the code faster. But such older games expect to find only 512KB chip ram. It finds more or expects any extra ram to be fast ram and the memory addresses the games coders have used are wrong. So the game crashes with that error message.

Sorry if that was an over complicated explaination, but that is the whole reason.

If this is what's happening there are programs and utilities you can run to make older games run on the A600. The best is a disk called ReLoKick 1.3. You boot the A600 with this disk and it loads the older Kickstart 1.3 into memory and reboots to its loading screen. You can then put the game that's not compatible in and it will load. Works for 90% of older disks.

The other issue might be the disk images themselves. When you write ADFs back to floppy disk, most methods of doing this won't work for all disks. Many games have their own special filesystem format that isn't the standard FFS Workbench system and will not write back to floppy disk using most programs. The only guaranteed way to write all disks back to floppy is a piece of hardware called Keyoflux.

These days I wouldn't recommend trying to keep using real floppy disks. The easiest alternative is to buy something called a Gotek floppy drive emulator. This is a device you replace the internal floppy drive with. It has a USB stick slot, and number display and a couple of buttons. You put all your ADFs onto a USB stick. Put that into the drive. Then boot the Amiga and use the buttons to select the ADF you want to load. The Gotek then loads the disk images and the Amiga thinks it's loading a real disk.

There are sellers who 3D print mounting brackets and sell them with the Gotek drives already setup to work on the Amiga. You just open the Amiga and swap the drives over.

WHDLoad.

You mentioned this, but said you were unsure what it was. It's a project that's been running for ac long time. It's software you install on an Amiga HDD and it allows you to install nearly all Amiga floppy disk based games on hdd. Even games that could not originally be installed on floppy disk. The WHDLoad project make disk installers unique to each game so they can read and copy the game to the hdd, even if normality you can't even read the disk in Workbench. Once installed a WHDLoad game will have a game icon in Workbench you can double click and load the game really quickly from hdd.

There are full game packs available, allowing you to setup a whole hdd full of nearly every game every released on the Amiga in A-Z folders all installed and really to run at the click of a button.

The only limitation with the A600 is you need Workbench 2.1 or 3.0 to run WHDLoad, and you need a minimum of 2MB chip ram and 2MB fast ram for it to run. So unless you want to start getting extra hardware to get it working the Gotek usb drive is the easiest solution.

Hope that helps answer some of your questions.
