I just bought a SD SuperCard. Everything was running fine, after 2 days. I spent last nite setting it up and it was well. When my son went to use it in the morning it loaded up in some other unknown language. He said he got it back in English by scrolling thru the menu and/or turning it off. I tested it, it was in English in 1 GBA SP and jibberish in another. I went out of the house came back later and both GBA's loaded it in gibberish. So I took everything off the SD formatted it and reset the firmware. Now none of the GameBoys recognize the SuperCard Cart at all. Help please.
