the reference to Iron blitz is for a bug that I have not fixed 🙁
however, I have created a patch for Iron Blitz ( that isn't done yet ) but should be enough to get it running. here
The fixes should be fairly generic
I don't have a list of ddraw games
Force Direct Draw Emulation + Fake Vsync should be tried for any ddraw game that doesn't run, is glitched, or runs too slow
( used it to get Cyber Gladiators running the other day )
Limit Process Affinity - is not for a ddraw issue but it is useful to have applied to games of the ddraw era ( smack videos played by Axis & Allies )
Blt Mirroring is used by infinity engine games like Baldur's Gate 2
Full swap flipping - fixes a issue with Planescape: Torment
Stolen palette fix - works for Diablo: Hellfire but may not work for other games such as Epic40k: Final Liberation
