-Call of Duty 5 works fine now. Earlier it didn't, but after I reinstalled Win7, its working fine. Maybe it has something to do with the fact that I'm now using PowerISO rather than UltraISO. God knows.
-Mirror's Edge requires Compatibility Mode in XP, and disabling of graphics. Then it works mostly fine, but there's no sound in its anime-like movies.
-Call of Duty 1, UO, and 2 all work. CoD 2 gives some sort of a graphics error at a particular level. Haven't found a fix for it yet..
-Sins of a Solar Empire works absolutely fine.
-Gears of War also works well.
This is all on Windows 7 7000 build, 32-bit.
