Any NT based OS doesn't have real DOS in it, it makes a Virtual Enviroment for DOS and 16-bit applications. I had WinTone running pretty good on an older computer from 1998 running Windows XP, but on a newer one from 2004 it won't run at all. Since my sound card is so new, I doubt I can find any DOS drivers for it so that rules out the DOS program.
EDIT: Actually, on the newer XP computer, it does run, but it doesn't decode properly and crashes when being used.
