Just got mine in today. I loaded the roms on to it in 2 separate folders - GB and GBC. I popped it into my GBA, booted it up and it gave me a disc init Cx08 I believe. So I turned it off, back on, and it immediately boots to a Kirby game that I assume is on the SD card somewhere (I don't remember putting it on there). So I tried it on the SGB, same thing, says disk init briefly, then boots into GB mode and loads the game up. I can't get it to go back to the menu.
Help?
