Not bad...

It's not speed so much as accuracy. I figure you'll be playing the DOS version of KQ5, and it'll work just fine with the other 4 games (actually 1-3 (old version of 1) will run perfectly in XP without even needing an emulator). I would highly suggest playing the Windows version of 6 though. Not only is it a LOT easier to aim the cursor (the smaller size is just about needed to click on certain on screen items with any accuracy), but the animated "character talk boxes" (I have no good name for those things) are "Super VGA" and look amazing. Captain Saladin looks like Lassi. That alone is worth it. It'll work fine in Windows ME as it's based on 9x, but not in XP without going through some extreme effort, involving some sort of sound system emulator. Actually, you COULD install Windows 3.x under DOSbox and then install KQ6 under that. That might work, depending on how well DOSbox emulates that old OS, and if you have a copy of 3.x lying around somewhere.

The problem isn't running the programs in Vista's version of DOS emulation, it's that as far as I can tell it won't let you run DOS things fullscreen... either I'm missing something or that option is gone, I don't know which. Anyway, as it is now emulation is the only way, sadly. Now that's why I stuck with that old computer so long... true DOS mode, right there in Windows... :(

It doesn't just run native in Windows? KQV's Windows version runs fine even in Vista, as long as you're in 256 color 640x480...

I do remember some games having some issues, but then I think I solved some of those issues with sound drivers from other Sierra adventure games that I have that use the same engine and use other versions of the drivers that worked... I know I made posts about that here sometime...
