it's not working for me (Ez flash omega), I get the prompt to update the firmware every time, which I can cancel by pressing B but then any game I try to boot doesn't work (it works perfectly fine on original hardware)
Were you able to solve your issue? I'm trying to decide which burner/miniDVDs to buy to burn Swiss and be able to use a gameboy player. (seems like it's impossible to get an already burned miniDVD with Swiss)
