ok, i want games and stuff like doom or neogeo and i downloaded the bundle of games that was on that sticky thread to my computer but i dont know how to get it on my psp. i have a usb cable but when i download the stuff it has corrupted data instead of the games. i can download chess and black jack but not the other stuff. do i need to upgrade to 2.0? i have 1.5 now. one of my main problems is trying to download 2.0 . sorry for the inconveinence but i tried looking in the book and on this forum but couldnt find it. thanks for the help.
