Virtual Game Station?
It was a short-lived commercial emulator that allowed you to play PSX games on the Mac. Sony quickly killed it(why, I don’t know. It was getting people who didn’t own a PSX to buy PSX games…what was so wrong with that?). Essentially you just boot the program, pop in the disc and it works. Like most emulators, it wasn’t perfect, and had its issues. One nice thing about it was that it did something a lot like the PS2’s “PS1 mode” did in terms of running a blur filter over the entire screen, thus taking the hard edges off those nasty polygons. I use VGS to get all of my screenshots for the PSX games, I then run Photoshop’s “Sharpen” filter over the pic to bring it back to what it would look like via a television set with S-Video hookups.
