I don't know if this is the right place to ask this, but here I go. I noticed something strange in both my O3DS and N3DS: Every time I open NSMB2 (either normal or Gold Edition), then press home and open a homebrew CIA program, the game tries to close in order to open the other program, but instead it gets stuck in a black screen. However, if I open an installed game like Kirby Triple Deluxe or DKC Returns, the latter opens properly. The workarounds I found so far besides opening a new game are turning off the system, and even opening a GBA game, inject or not. Does anybody know what the cause of the problem may be? So far, Quick Reboot and Quick Shutdown are unaffected by this.
