Chrono Trigger 1.0 seems to run well, no audio on the FMV but the gameplay and other sounds/music seem to work quite well indeed! Always a plus in my book.
Please remember that this a prototype device and does likely not reflect what the final hardware will be like. This includes compatibility with games as well.
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.
