Hey, I've had my MK2 for quite some time but never had much of a problem with it until now. I have menu 0.6 beta 2 and an EZF Advance GBA flash cartridge. Something weird happened when I tried to flash the new menu from the SD card in my MK2. When I tried running the MK2 after the flashing, the Moonshell menu boot automatically completely skipping the MK menu. I had moonshell on the SD card at the time, so I tried a different sd card that did not have moonshell and moonshell still booted up.
The only explanation I can come up with is that the MK2 must have flashed moonshell to my cartridge instead of the menu. Also, I my cartridge no longer works in the GBA slot or on another GBA, so I have no way to reformat or flash a new menu. If someone could help me figure out how to fix this, it would be much appreciated.
