Sometimes when I start my DS with the M3 card in it it gets stuck at the white screen after I see loading in the bottom corner. So basically its the Nintendo Warning thing, then black screen with M3 Loading in the bottom right corner, but then it goes white, but it stays at white either for a prolonged period or freezes there entirely what would be causing this?
Paper shim trick - try putting a thin piece of card between the back of the M3 and the back of the DS slot. This symptom is usually a sign of poor contact
