If you are referring to my post, 98Lite is a special program that you can download to decreace the size of win95, win98 or win98se. You can manually select witch part you want to remove (example IE, networksupport, enz.).
Well i have tested sonic 1 & 2 and sf2 turbo so far and they all work!
The games run around 23fps, sf2t has some grapical glitches but runs okay. Sonic 1 & 2 run great, there is only some garbage at the right of the screen. So the speed and smoothness are really nice for a first release!
