Hi there, does anyone know the reason these are pre-flashed? I thought the r4ds takes care of that. I just bought a crimson red ds and r4ds and it won't boot, whereas my friend's older ds lite works fine with it. I believe these new Crimson red limited editions have a new chip that prevents such passcards from working...anyone have any knowledge on that? I'd rather not go through the headache of returns and argueing with salesmen etc.

any help would be greatly appreciated
