Hi m8,
There i only one chip that will work 100% with the PS-One and the name off that chip is Onechip. This chip boot's all regios! When you use a old chip you can only boot the games from PAL if your ps-one is a PAL version! Or NTSC if it is a NTSC version.
It's a 8 wire mod so all site's that claim the have a 100% PS-One chip and the have less then 8 wires they ####ed you up!
Never ever by a chip from www.modchip.com because the are lamers!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
And please believe me because i have modifyed hundreds off this consoles.
If you want more info you can mail me at
