it might stay in on a 03ds, on my new 3ds xl the acekard 2i and r4 ds flashcarts all pop back out the slot again, they wont latch in
, yet official stuff latchs in fine, no one`s noticed this, must be a later model thing.
If i ever had to use that new magnet hack to unbrick i think i would need two people, one to hold the acekard 2i in and one for the button combo lol
