Since I have to wait till The Wii comes back in stores again I will focus on my PsP.
I changed firmewares and putted loaders on it in the beginning of the psp but did reset to factory settings planning on selling it. But I did not sell so now i can start over again.
With the custom firmware you shouldn't need a loader. You should just put your iso or cso into the ISO folder on your memory stick and it should show up in your menu in the XMB under psp->games->memory stick. Press X and it should load the game all by itself.
