Any chance of this app adding something like the National Pokedex functionality that the official bank has? Or is that something for another application?
It really sounds like something wrong with how the d-pad is doing debouncing on some consoles. Dirt or corrosion on the contacts could possibly cause it, though admittedly I don't know how the 3DS does debouncing.
Maybe they forgot to add the new external module libctr9?
Latest commit from master builds fine here on RPi. It didn't like "make -j4" for some reason but just "make" worked.
MHGen is my current obsession too >_<
Yes, MHG keeps the save file in the ExtData.
Use any name you want. The right shoulder button automatically fills in the current date and time though, which is quite convenient.
