I installed my E-Matrix 68030 40Mhz from Amigakit today and I set up work bench in WinUAE directly to the CF card I use with my 1200 as the hard drive.
Everything was running smooth as could be on WinUAE, but when ever I try to load a WHDLoad game on the real Amiga, I get a ton of garbage on the screen and have to reboot.
Nothing works.
BTW I do not have Math Co-Processor yet.
Math's co-pro has nothing to do with it (eg 99.99% of games won't even use it).
Two most obvious problems are power supply and memory corruption.
What OS is it?
Have you got the 3.1 boot floppy?
