Hi, LPH, thanks for sharing your experice on making DK2 works under windows XP SP2. I agree with you that we should emulate a slow CPU, and I tried Windows Application Compatibility Toolkit 3.0, I clicked select EmulateSlowCPU and installed it. but it seems nothing happened to DK2.exe under your step, and Dk2 keep crash constantly. And I found if I use the lowest speed to play game, it will not crash, but that will be too slow.
