You need an emulator program and the corresponding ROMs. A ROM is a digital copy of the cartridge. It is illegal to download and play any ROM of any game that you do not own.

Another way, that is legal to play if you do not own a copy of the original game, is to subscribe to GameTap.com They don't have every game ever made, but they do have many of the popular classic games.

Phantasy Star. Before SEGA ruined the franchise by making horrible MMOs. 1-4 are pure classics, though.

Commandos

Kings Quest

Doom

Blood

Mutant League. (ML Hockey was kind of weak, but still pretty fun. Why in the 9 Hells hasn't EA resurrected this franchise?)

Road Rash

Soul Edge/Blade/Caliber/Whatever

Winning Eleven/PES

-edit-

 How could I forget to include the Metal Gear series? Especially since I've played each one since the NES days. :D

 Gran Turismo

Wolfenstein 3D

Onyxia

I got starforce on my comp when I installed Splinter Cell: Chaos Theory. After I beat the game I reformatted. Partially because of StarForce, but mostly just to begin with a fresh install of XP.

I thought publishers would have left StarForce alone after the whole GalCiv II thingy and Ubisoft dumping them. Guess some publishers are just too retarded to care. 

Thanks for the heads up. 

I thought they were pushing Endwar to have top notch Graphics as well? If so I would buy a decent card of course by the time it does come out prices wil have most likely plummeted.
