Reddit mentions of PS - X - Change 2

I use this to play Japanese imports on my North American PS1. I've only used it for 4 imports, but it's worked on all of them. It's just a boot disc that boots past the copy protection then lets you swap in the import. I have used this to play a few burned games as well. I ordered a copy of Diablo 1 off ebay but it wouldn't play, so I burned a disc of it and it worked great. Not as elegant as a modded system for sure, but cheap and effective!

I bought this off amazon and it works like a charm. It's a disc that boots past the copy protection, then you remove it and insert an Import/Burned game.

I have played both Japanese games and burned games on my North American PS1. Works awesome!

You did not need a mod chip. The simplicity of some of the tools for playing PSX games that you'd burned was astounding. I had something called the PS X Change. It was painfully simple. Also that expansion port allowed piracy too if I'm not mistaken (the one you plugged the Gameshark into).
