I extracted diggerc, and went through, and all was well, i added the cvs resource, and it repeated the problem. i extracted the dat samples from both the version of the dat i use (robber804) and one directly from mame 97u1.

I also tried extracting the zip file completely and rebuilding from the individual roms with no luck.

I have rar'd up both dats, the exact zip file I have been using, as well as the two .cmp settings files.

I will email them to you promptly.
