Ds1 extremely upset.
He leant the cartridge to his brother (played on a separate gameboy - we assumed the games were saved on the console not the cartridge DOH) and thought we'd set it up on Game 3 save anyway just to be sure.
However, ds1 got the game back and while it's still saying he's got 47% through the game, it's lost all his money and characters he's earned - surely if ds2 had accidentally saved over the top of his old game then it wouldn't be 47% through still... any ideas a) what's happened and b) if there's a way of getting his characters back.
I'd settle for a cheat code that would get all the characters back for him
