I don't know how useful this info is, and I know this software isn't exactly 'finished' but it doesn't really work on my PC (It's a Windows 7), when I click on it it spends a long time "not responding" to then be terminated, and when I try to open a .dmf file with it it once again spends a long time "not responding" but this time it does indeed open, for a fraction of a second and then it closes itself...
Hahaha ... you're not old-skool enough, and I forgot to make it user-friendly.
It's a command-line tool and not a Windows application.
You open up a command prompt, navigate to the directory that contains dmf2pce.exe and the .dmf files, and then run ...
dmf2pce "Misty Blue Opening.dmf"... (or whatever you .dmf file is called) and it prints up a bunch of information.
I'll cook up a batch file to make it a drag-n-drop process for the next version.
