PSIO is simply a development cartridge that plugs into your PlayStation’s Parallel I/O Port. It allows you to instantly see your software running from an SD Card on real hardware, making it the ultimate developers tool, as well as making it invaluable for debugging.
PSIO Cartridges are currently sold out but more are being manufactured.
