i really want to play backup games for my psx. what do i need to play it. i really dont want a mod chip that u have to solder wires in the psx. is there like an external mod chip for psx?

if so, where can i get it? if u dont mind, can u give me some very reliable sites american sites that sells the external mod chip for psx, the one that dont require soldering.

Check out www.gamegizmo.com/ they have a few options for you
You can get a Game enhancer which plugs in the back of your console (Depending on your psx model) or you can get a Psx exchange disk which boots about 98% of backups, further options can be found on my link site.
Good Luck

The game enhancer only works if you have the parallel i/o port in the back of the playstation. If you don't have one you could buy PS-X-Chance 2 Modchip CD. Its basically a bootdisk for your playstation, and it works with both models of the playstation.
