A few issues

[rvo_nl]

well, you need to tell us a bit more about your machine. what are its specs? a standard a1200 without any extra memory it will not run Land of Genesis (I assume thats what you meant). Then again, virtual memory IMHO is not very useful, though I did play around with it once. Theres not a lot of software that supports it. I did manage to run Microcosm on my a1200 but I dont know how I did it, I believe using the AsimCDFS package. Cant help you with the rest, sorry.

1 - It's the A1200 CD version. I tried running from a boot with no startup and thats where I get the message. I'll try the flush and avail commands

strange. could be something else though. Try with different setpatch, disabling caching etc. also run snoopdos when you start the game to see if you're missing something.

5 - Both PAL. I'll check out AsimCDfS. On quick look it appears not to be freeware/pd is that right?

hmm it seems so. Well, I guess its okay to try it before you buy it, so Google around.

For certain games you may need to fall back to the 020. I don't know if the Viper has a switch for 020/060 or not?

note that its a fairly new game that has a 040 as recommended cpu.

as for your last remark, the asimcdfs package comes with AKIKO emulation. apart from that, microcosm didnt really use the akiko chip.. please try booting without startup-sequence and manually doing all the work, coz thats what you'd have on cd32, too.

If I find time I will try to run this game myself this weekend and let you know how

well, that wasnt too hard I just used Ide-Fix, I didnt know it had cd32 emulation built in. Just had to select the right device name, disabled fastmem, pressed start and voila, there it was. Microcosm, playable and all that. So I suggest you give Ide-Fix a try!
