Yesterday I took apart my r4i (yes, i know, pretty dumb). anyway, i took the plastic modeling part, which is the bottom half of the r4, and inserted it into the slot. now the half-chip is stuck there, when i eject it i here the clicking noise but then only 1cm comes out. i tried to pull it out but that didn't work. i have a feeling it has something to do with the clip on the left side of the slot (when facing the back) but i'm not sure. anyone have any suggestions?
