My PSIO Cartridge isn’t working!

  • If your PSIO Cartridge refuses to boot, the first problem is because the Switch Board has been installed incorrectly or poorly. We offer a service which is that you may send in your board to have the Switch Board professionally installed by us, and we highly recommend that if you are not competent with a soldering iron that you let us do it for you.
  • The second problem is usually because the Parallel Port in your PlayStation is corroded or dirty. After all, these ports never or rarely got used, so for them to make a good connection with PSIO requires them to be in good condition. To achieve a good connection, one method is to unplug and re-plug PSIO several times (please read the Systems Manual on how to correctly remove PSIO) which helps strike the pins on both your console and PSIO to help establish a good connection.

My software freezes!

  • If your software freezes, be sure to try different XA/CDDA patches in the Menu Systems Options screen, and also remember to check whether your game uses LibCrypt. You may check that by using
  • If your software does use LibCrypt, it must be patched using “PPF O MATIC” patches. More information can be found here.

Is there anything I should know before ordering a PSIO cartridge?

  • Be sure to read our FAQ. It contains many important and common questions that have been answered already.
  • You must have a PlayStation 1 with a “Parallel Port I/O” connector.
  • A Switch Board must be soldered correctly to your PSX mainboard in order for PSIO to work correctly.
  • Your PSX must have a good quality Parallel Port with no corrosion.
  • Detailed instructions on how to solder the Switch Board to the mainboard may be found here.
  • Failure to install the Switch Board correctly will render your PSIO cartridge useless, and possible bus contention whilst attempting to run PSIO without a Switch Board can cause damage to your PSX system.

What should I do when I receive my cartridge?

  • Before plugging in your PSIO cartridge, you must have the Switch Board installed as mentioned in the included “Quick Start Guide”.
  • Once that is done, you may copy software to your SD card within folders/directories. EG: [SD:\Folder\GAME.ISO]
  • Next, copy the MENU.SYS file to the root of the SD Card.
  • Lastly, power on your PSX.
  • For detailed instructions with a full comprehensive list of explanations, please see the “Quick Start Guide”, and also the “Systems Manual” PDF in the Downloads section here.
