I tried like 30 ps3 games on remote play and it wouldn't let me play any of them. Which games other than ps1 and pspgames can you play? Is there a list?
It hasnt been updated with God of War Collection and Ico and Shadow of the Colossus yet though.
I think any game that worked on the PSP should still work, in which case there are more than just those. Just looking at a few, the ones on wikipedia that they hadn't reported weren't on the "confirmed not working" list.
