i'm having the same problem. i've googled every which possible phrase to find an answer and i've tried all the sram patches ez 3in1 tool and no go. i am currently on akaio 1.5.1 acekard 2i and ez expansion 3in1+. when i use akaio to flash to NOR, it initially opens to "GAMEBOY" without the 'nintendo' under it. i then turn it off and back on, load it through the slot - 2 from the menu, it loads with the 'nintendo' and then goes to a scrambled red screen and then a scrambled greenish screen and then it stays that way until power off.
so now i try exploader .58b and it erases current NOR and then when it gets to flashing to NOR it gets stuck at 0% forever. the process goes 'erasing NOR' -> 'analyzing game' -> 'flashing NOR' (and this is where it stays at 0%). so i'm at a loss. VBA runs the rom.
i've tried the new translation patch, old translation patch, and already patched roms. nothing. would love to play this game on the go but this is getting hopeless for me. please help.
