Ok, I showed my friend the awesomeness of Homebrew and so he wants his PSP rigged up like mine. He has 2.80 firmware, and lucky him, his mother board is not the TA-082. So I downloaded the 2.80 EASY downgrader and followed the instructions perfectly. Formatted the memory stick, connected his PSP to the computer with USB cable, installed the downgrader to the root. Everying installs OK. So I reset the PSP, and go to the game folder and select the downgrader, it then says the game could not be started!!! Can anyone help? Is there a guide to manually install it? Mine was 2.81 with the Ta-082 so I think I'll be ok with his NON-TA-082 2.80 to set it up. Thanks appreciated it.
