Crashes before map selection if you don't comment out the mapname parameter in the config.ini file. (I'd ship this commented out by default).

I'm writing a level editor for MM6-8, and it looks like you're parsing the same blv and odm files that I am. Perhaps we can collaborate.

I have almost the entire odm format decyphered (I'm still not sure what the section between sprites and monster spawn points represent, although it's some kind of mapped information.

I've also got some of the blv format decyphered.
