Well that 'shortly' ended up getting much delayed!
A couple of things I've had to correct in the DATs I included:
- remember to include "_CM" in the DAT file name, right at the end
- Apple III - Collections - WAP III SIG Public Domain Library -> you can't have (disk 1 of 1)(side)(media name), so I had to change a couple of those
- for some reason, all entries started with <tab><space>" rather than <tab>". Maybe you using DAT generator other than CMP? I changed them anyway as it pisses the TDE verifier right off...

Additionally, "Applied Technology Microbee - Educational (TOSEC-v2012-08-27)" is blank? Only a header included.
