According to the manual, VGS will not work properly on Macintoshes that have been upgraded with a G3 processor card. However, S onnet Technolgies recently pointed out that they ran VGS on their G3 processors without a hitch. Also note that VGS may not work on clones that don't have Apple standard CD-ROM drives. VGS also requires an ATI Rage II, ATI Rage Pro, or RAGE 128 video. Connectix includes special ATI drivers on the CD that you must install.
Installation takes but a matter of seconds.
After VGS is installed, all you have to do is pop in a PlayStation game and VGS' autoloader launches VGS and then the PlayStation game. After installing the Game Pad extensions, I ran VGS along with my Game Pad Pro without a hitch. In the Preferences you can also create and use as many memory cards as you like. The memory cards allow you to store and restore saved games. A few sites such as VGS Heaven have been making memory cards available you can download so you can start at a saved slot.
