So here's the situation:
I have a Commodore 386sx bridgeboard upgraded to a 486slc ( or something like that ) with a Math.co 387sx fpu and 4mb ram.
All seems to work fine apart from Dune2 where the graphics go bad ( see pictures ). I use the uncracked cdrom version, 1.07 ( with or without 1.07fix ) and it happens both when I play from HD or straight from cdrom. I tested 3 vga board, removed the fpu, turned on/off the cpu cache and/or clockdoubling, turned of vga and bios shadowing ... to no avail. Also the setup program tends to go bad at moments with funny characters in the text. Ingame it seems to be the scrolling that evokes it.
I am really lost here, I also considered that maybe the cpu gets too hot despite having a big heatsink on it but considering the fact Dune 1 with it's fancy intro and animations runs just fine I doubt it. I also have 612kb of base ram free while it says it needs 602kb and I get the message "taking advantage of extra ram" when I start it.
