Right, I've just done a few checks on the compatibility of the 68000 chip with various combinations in WinUAE. For starters the bad news, you can't use kickstart 3.1 with 68000 as it needs 24 bit addressing apparently. That's the bad news. On the upside though, using an A600 ickstart rom, you can use an HDD image, and easily install workbench 2.1 on it - so WHDLoad should be able to run from that. Cause my memory is usually reliable I didn't quite believe it when it told me I couldn't run Workbench 3.1 on it though - and just for that lovely ego boost I needed I found out I was right. You can't install wb3.1 unless you have kickstart 3.1 installed and a 68020+ CPU - but AFTER it's installed to HDD, you can then just change back to the A600 kick rom with 68000 and WB3.1 boots just fine ***(wonder if XP would run fine on my 486 if I just installed it using my P4 chip first... HA HA HA)***. So there's the results for all of you who were interested - which is probably nobody. Oh, and ALL installing and testing was done with OCS only, so no ECS or AGA chipset is needed anywhere along the line - 2mb chip and 8mb fast as standard (which is going to be needed for running WHDLoad installed games). In conclusion - PUAE/UAE with cyclone 68000 incorporated should be able to boot and run games from HDD without any problems, I personally can't wait till someone give it a shot! Contact me if you think I can help in any way, regarding testing or roms/software I used.
