PSIO is a development cartridge that plugs into the PlayStation's parallel I/O port and allows you to run software from an SD card on your PS hardware. It's the ultimate developer tool and an invaluable asset for debugging. Please note that this is not a plug-and-play product. In order for PSIO to work with your system, you need to install a switch board on your mainboard. PSIO will not work on systems without a parallel I/O port.
