Play any PS1 title via remote play | PS3Blog.net
Like ehandlr pointed out in the chat box. You can play any PS1 game downloaded or disc via remote play. Man what a stealth update! You just need to install the 2.10 Firmware on the PS3 and the 3.80 firmware on the PSP and your set.
I gotta try this out tonight. MGS & FF7 hear I come 🙂
