I have a r4 card, that I bought about a year ago, and I have no idea why, it shows the gba games, but doesn't allow me to open them, I've tried to open an options menu, but nothing shows up, I've looked into the .ini files in the sd but I'm too afraid to change anything, not wanting to damage it or something, does anybody know what can I do to make it play the gba games without an emulator?
