I've got a few older games (Redline Racer, Star Trek Generations and Mechwarrior 2 Titanium Trilogy) which I've been unable to get working using my normal methods. I would like to get my old copy of windows 98 running in VB to play these games, but I've read that it's very hard to get 9x windows working properly in VB and that it runs very badly.

Any help/advice would be appreciated.

Look at the top stickies in the Windows Guest section. There is one dedicated to Windows 98.

I would try Qemu (0.9.0) - most likely it runs faster and you'll have less problems with video (graphics). May require a little tweaking to optimise performance.
Of course it's better if you can get a patch to run them on a more modern OS....
