I've been looking around for about 6 hours now and have been unable to get any results to this as of yet.

My DeSmuME starts up just fine, lets me open .ROMs and everything. In fact, every other ROM works but the one I'm trying to play (Heart Gold).
As soon as I load Heart Gold, the screen just stays white and on the command prompt window that opens with DeSmuME it gave me an "sndxx emergency" error or something along the lines of it.

I went around and changed the "SoundBufferSize2" from something in the 5,000s down to 2940 which I read was the default setting, and now it's not giving me any sort of error, just the default "OpenGL successful initation" or what have you and a blank white screen on the emulator itself.

SoulSilver still works. Help?

I actually DID fucking read the FAQ.
