Old XP-era games

My comfuser is running 7 Pro 64Bit w/SP1. Is there any way to get these games:

Slam!
Sabacc
Jezzball

to run w/o having to install XP inside my 7 machine?

Have you tried running or installing them in comp mode?

Apparently, all those are far older than "XP-era". For the few things I just saw about them, they're built for Win 3X, so it's not possible to run them on x64 Windows. The main problem comes that x64 Windows cannot run 16 bits programs like your games.

So no, it's not possible to run them directly. Workarounds include a virtual machine running XP/98/3.1/7 x86, try to get a newer, 32 bits version if it exists or dual booting into one of those OSs. A virtual machine is often the easiest solution, and for those games performance isn't usually a problem.
