I'd love to oblige you, but I love my gp2x. Maybe you should try sell your PSP on Ebay, and buy a
http://cgi.ebay.com/Game-Park-GP2X-MK2-Han...1QQcmdZViewItem on ebay? (not my item, just a quick search)...
That's gonna be my next step if I can't find any takers here or on hardforum.com. I figured maybe someone here had a second GP2X and would be willing to part with it, or perhaps just wanted to take advantage of the PSP and make a bit of money off of it.
Hell, someone may just want to use the thing too, lol.
