This may seem to be difficult but it’s actually quite simple. But be noted, that not all games (very small number, for example Crash Twinsanity) can be played, and I don’t seek to know why.
I have converted many PS2 games to pkg files to install on PS3, and I think it’s better this way as I don’t want to do what I wrote in my other post anymore, though you still need to follow the set-up process for PS2 games from there (you can consider this is is Part 2 for PS2 games).
