Recently EA released the first few Command and Conquer games for free on their website. I've downloaded and installed the first one for 64-bit (the download for 64-bit versions of Windows can be found on the installation instructions page). Anyway when I play it it looks horrible. For some reason I'm getting graphical output errors, mainly just with the FMVs, but there's also some minor ones during actual gameplay. I was wondering how to set it up to look better. I know I've done it in XP before, but I can't remember what I did. It would also be great to be able to do this with any other old games I have (like Battleground Gettysburg).
EDIT: I have tried checking the "Run in 256 colors mode" option. It didn't change anything. I think this is because Windows was automatically doing that anyway.
EDIT2: I've also tried running it in XP Mode but couldn't get it to run.
EDIT3: I know it would probably help if I had screenshots, but every time I try to make one it only captures the colors that are off, with the rest of the in game screen being black. Thus they don't really help out of context for what the screen looks like.
EDIT4: It turns out this question applies to other games, so I have generecized the question to better reflect this fact.
