Gran Turismo 2 did not have much luck on this PSIO 1.1 prototype setup. I’m hoping the improvements in the upcoming 2.x PCB hardware will bring much better compatibility!

Please remember that this is prototype hardware. These results, including game compatibility, may not reflect later revisions or the final product.

You can hit up PSIO if you have any questions, since I am but a mere tester and don’t understand the technology behind this wonderful invention.
