I tried remote play with a few PSX games, it doesn't look too good, the image quality drop is noticeable.
Regardless, it's nice that the option is there and I think it should be universal for all games. It's great being able to play your PS3 games anywhere (near wifi) so if I go on holidays I can continue playing in the hotel, for instance, even with the quality drop.
No troll is too much for me to handle. I rehabilitate trolls, I train people. I am the Troll Whisperer.
