There's a thread on these boards on how to fix the game so it plays on most flashcarts by altering a hex address. This has worked for me, and I use a Supercard One (just regular one, not onei) I can't save the game, however. When I do, the save disappears when I shut the ds off. Does anyone have any ideas on how to fix this? I haven't seen anyone else with this problem when I search google and these boards, so I am probably doing something wrong on my own. Any ideas would be much appreciated!!
