This would be nice, similar to the "Switch screens" button.

This sounds like a rom issue, as I've yet to find any issues with running this game, and I've played all the way to the credits.

Are you guys using a clean rom, or a patched one? There have been a few releases of a patched version that fixes a lot of issues put into play by Nintendo to stop piracy.

This happens far too much in almost every Pokemon game (Except B/W and B2/W2). The game acts like the rom has been completely unloaded, and is unable to load anymore data. It usually happens to me after switching rooms or returning to the map from a battle. Sometimes you get what's pictured above ...

I've played through the whole game with no issues whatsoever.

If you're getting crashes, turn off multi-threaded rendering. I couldn't get past the first world in NSMB with this on, and have not even tried it on Black 2.

This happened to me after I updated the application. What I did was I deleted my save states and re-installed the app. I recommend backing up your game saves (Not save states) before doing this though because when I did this it removed my save files.

After that, it should work again. Good luck!

I finally decided to purchase this emulator today, woohoo!

My saves always worked for me... You just have to reset the game before loading one or the game crashes. I played through the whole game and that issue only bugged me for half a second, until I looked into it for a minute.
