Takes the debug file created by using ld65's --dbgfile <filename>.nes.db option and outputs a symbols file that can be loaded into Mesen's debugger.
A few lines from a dbgfile *.nes.db (a lot of lines have been removed for brevity):

And what they turn into in the *.mlb output file:
R:0004:BTNPRESSEDMASK
R:0004:CONTROLLERTMP
R:0003:CONTROLLER2_OLD
R:0002:CONTROLLER2
- I haven't extensively tested this. So far, I know it works for the specific MMC1 iNES configuration that I'm using.
- Test the FCEUX output with more than the specific iNES configuration that I've used.
