I own a PSP and have some great retro games for it. I don't have any emulators, but I've bought all the retro games collections they've released so far.
I have the Namco collection which has Pac Man, Galaga, Dig Dug II, Mrs Pac Man, Xevious, and a bunch more.
I just recently got the Midway collection which has Spy Hunter, Defender, Paperboy, Marble Madness, Rampage, Mortal Kombat 1-3, and a lot more.
I also recently got Pinball Hall of Fame which is one of the best pinball games I've ever owned.
Personaly, this is why I bought the PSP. For old school retro games. BTW there's a couple of MegaMan games coming out for the PSP this month. Both of them are side scrollers and I believe one of them is the original games with updated graphics. Awesome.
