PSIO | PlayStation Input Output

Total progress on PSIO


What is it?

PSIO is a cartridge that plug's into the back of your Sony PlayStation 1 console that will let you play your backed up games from an SD card. It will also allow you to boot and run code you have programmed and compiled from an SD card on the actual PlayStation 1 console itself, making it a must have tool for homebrewers, developers and most importantly, gamers.

It's been a while since we have shared an update, so what we have been working on is actually getting the code cleaned up and incorporating the eXtended Architecture as well as Compact Disc Digital Audio functions. We are up to hardware version 2.0, but here are some old videos of the 1.1 hardware for your enjoyment. Remember that the 1.1 hardware is now completely obsolete, and new videos of the new 2.0 hardware will be coming soon. Click the 'Playlist' option on the top left of the video to see the playlist. A thanks goes out to Shane for making the videos.

The complete compatibility list of games we have tested may be found here.
