Re: old 286, what to do with it?

in PC Emulation
Well games can request memory by different means: below-1mb ram, ems, xms, int15 (bios interface) or by switching to protected mode. In your case ems will be missing, i'm not aware of a tool similar to emm386 for 286 systems, but you might want to try looking for such a thing.

prefix_none.h for the normal core, case 0x8e: MOV Sw,Ew where the which (==seg reg ID) is 1. See CPU_JMP (the stuff in the first if() block, which deals with real mode far jumps) for how to change the cs segment, ie. use SegSet16(). I've removed the archive btw.
