Damn!
Maybe there would exist a way to make WinCE thinks it's running the game on a US or Japanese DC (by using a special boot-disc?). Maybe we just need to find the region flag WinCE detects to fool him??? But if the code of WinCE is different in PAL DC's ROMs, we should then make a TSR that intercepts the 50Hz switching instruction on the fly... It's just ideas, I'm not a coder so in no way the "we" I used several times above include me
Is there really no solution???
Note to roBx^ -> the Zombie Revenege I got is the original PAL GD-ROM (as well as all games I mentioned in my first post) and it *seems* to run at 50Hz because there're black borders on both top and bottom of the screen. But it's only a guess, maybe it runs at 60Hz after all... (I became a bit paranoiac about this with the time).
