You can just barely see in the top right corner a tag on the box saying "Works on Windows XP". Not sure if it's recompiled or it they run through an emulator (or if that's an empty promise), but in THEORY they work on XP.
If you want more, EBGames also has
Police Quest,
King's Quest, and
Liesure Suit Larry collections all just added, all for $20. The King's Quest one goes on sale tomorrow (at the time writing), so there may be even more on the way.
