I was wondering if someone could shed some light in my generally dark direction. Just got the iPlayer, went through about 10 steps to get the OS on there. (The whole fish tycoon game screen, etc.) Next I downloaded the GBA emulator from this site put the English version in the /_system/ folder of the MicroSD. Made a Games folder on the root and put 3 GBA games. I can't access them from the homebrew option in the menu. I can locate them using the files (file browser) option, but when I click on the game it says: Warning! This is unknowned file!!! Unknowned indeed .... Have I forgotten some important step? Any help would be greatly appreciated.
