I'm trying to insert the R4 into a new 2DS and it just doesn't stay in. It barely works on my DS lite when I push on the corner where the sd card slot is then it will click and stay in. But on this new 2DS it just doesn't work. I tried wiggling it, I tried pressing hard, I tried pressing the sd card corner and the other corner, it won't click and stay in. The housing of the R4 is bad I'm guessing but which part? Can I do anything on the R4 that might help? Any info is appreciated.
