Don't worry, RE1 is getting some good deserved love, too.
All the experience I collected while patching RE2 is going to be used for some very effective hacking, including some quick port of Mod-sdk, which is already in there, it's just not hooked into anything really. The screenshot in this post shows a borderless fullscreen mode, something that the original CR1 could never do because I had no idea how to do it.
The big news is: hardware mode is operative, had to strip DXGL out to do that. Seems rather stable so far and it's fully compatible with dgVoodoo + Retroshade.
