Yeah, back in Vista Beta I did it and it put all of my files in Widows.Old so this should work for everyone, you will have to go back through Computer>(Active Disk)>Windows.Old.(Whatever you want to access)
I have a Sound Blaster Audigy SE cheap card from Walmart, it does not work and I've downloaded three different drivers none work, I guess I'll wait for Win7 drivers to be released.
Good job dude, this should be interesting, I remember MM2, it was great. MM2 had alot of good cheats and mods, great fun. I can't wait to hear if this works!
