Desmume crashing when starting a ROM

[NoroTM]

I don't know which button I clicked, but I'm sure it was the "+" or "-" on my keyboard, and it was completely by accident, but because of this small error my Pokémon ROM simply crashed and now it doesn't work, it even starts but when the game's initial screen appears, desmume simply crashes

oh i just found out that every time I press the minus ( - ) key on my keyboard, Desmume just crashes, and the game ROMs stop working

[rofl0r]

give some more details about the version you're using. windows, linux, mac, version number, etc
