You haven't read carefully ;)

ClrMamePro supports 2 ways of storing your sets:

1) [rompath]\[setname]\[rom 1...rom n] for unzipped files
2) [rompath]\[setname.zip] for zipped files

so...you can:
- zip the individual files (or use the rebuilder to do the job)

or

- modify the tosec dat (convert the multiple games with one rom each to a one game with thousand roms)

or

- if you want them unzipped and don't want to modify the dat you have to make subfolders for each and any file...


I'd zip the individual files.

A better one-file-per-set/unzipped scan support is planned...but not in the near future.
The 2 scanningmodes result of the fact how most emulators look for romsets. Tosec collections usually use these 1-rom-per-set stuff....which is a bit special.
