PSIO is a hardware emulator of the CD-ROM sub-system and it was designed to keep your PlayStation as factory as possible.

Unlike other devices on the market, PSIO can be unplugged and modifications to your PlayStation circuit board to get PSIO to function are much simpler. In case you also want to play from discs, your original CD-ROM drive will still be present and will still function exactly the same

Product Reviews

My Life in Gaming


"PSIO is certainly a marvel. An attractive polished product with excellent presentation. A device unlike any other that anyone else has yet taken the investment of time, effort and money to engineer for one of the most successful video game systems in history."

Retro Man Cave


"This device really does show the maturity of a product that's been in ten years of development. It has a lovely injection moulded case and packaging that looks like it could have some straight out of a Sony factory. I really think it is a must have for any gamer or homebrew developer."

Metal Jesus Rocks


"Plays a ton of games off of an SD Card and it works with your original video cables. For me, that means I can still benefit from playing those awesome Lightgun games. PSIO runs all regions and playing backups like this is really nice."
