Cpajuste calls them crappy, but we think they're the start of something really good. He's ported some old GP2X games for use with the PSPs, and while all the features aren't there yet, they're pretty nicely made ports.

The ports are of the following games: DCircus, Defend, Dodgin Diamond II, Pang, and Yeti3D. Now, there aren't any real instructions for installing them, but they follow your standard eboot installation procedure, so you should be good to go.

As for the individual quirks that have come up (since Cpajuste did do this for learning purposes), the readme texts on each compressed file should tell you what bugs or problems exist on the games themselves. Enjoy!
