Grandia, so close to working! I bet it’s been nailed on 2.x hardware. Any progress is progress and the team at http://ps-io.com have been hammering along.
You can hit up ps-io.com if you have any questions since I am but a mere tester, I do not understand the technology behind this wonderful invention.
PSIO Hardware Version: 1.1
PSIO Software Version: 1.1A
All tested on an SCPH-5502 with a missing CD deck.
