Guys, lucky today, i founded the game, in $150MX, (very cheap, uh?) Well... i looked the Motherboard, and... SURPRISE! The JP motherboard have a battery! (NOT MEMORY FLASH!) But YuGiOh! Worldwide (USA) doesnt have a battery, a Memory Flash! By the way... i noticed the game inst in Google, so, i already extracted the ROM, and tested with VBA, And worked! (THE GAME IS MULTI-REGION!) So, if i want to upload the ROM, how i can?
