Trying to figure out what to do with my old computer that I don't use anymore. Haven't used it since I got my editing rig. Might just give it to the girlfriend since she doesn't have a computer.
Computers don't grow on trees , give it another purpose like I did mine since giving it to whoever is just asking for them to total it.
THE BEST METHOD to run PSX games (and everything else for that matter) is via Retroarch - http://buildbot.libretro.com/nightly/
If you have any questions on how to set it up on Windows please feel free to ask, its very easy.
