What game system are you trying to emulate?
Or are you trying to emulate a windows 9x OS?
What games are you trying to run?
If its an older game maybe they made it for a console system, you'll be able to find those emulators more easily. It would probably be easier just dual booting with windows 98 rather than trying to emulate it, after much googling I only found Mac OS, windows 9x emulators. Emulating windows for the sake of running it, would rather defeat the purpose of using a PC, and most emulator makers probably felt the same way. Also you could check out the game manufacturer’s sites to find a compatible version or a patch.
