don't really have a backlog just (well lunar 2) was looking for a decent psp rpg so I grabbed those first two.
PSP has a ton of good RPGs, you want me to throw you some suggestions?
THE BEST METHOD to run PSX games (and everything else for that matter) is via Retroarch - http://buildbot.libretro.com/nightly/
If you have any questions on how to set it up on Windows please feel free to ask, its very easy.
