I have used CMP for the past year or two to handle the dats for the ScummVM Collection. A common problem I've had with CMP before is that rom sets with directories in them are often scanned as incorrect, with errors about unneeded folders. In the version of CMP I was using, which was a year or so old, there was an option to disable this error. In the latest version I have tried creating my dat (using dir2dat) with set-subfolder mode checked and unchecked and add 0-file for empty folder checked and unchecked (since none of the directories are emtpy though, this should not be the problem).
I am posting to check and see if I am missing something, or if this is a bug in the way CMP is handling the dat creation. I do not want to release dat files for the new ScummVM collection if it runs the risk of someone rebuilding their set only to have this remove what it considers to be unneeded folders (which are very much needed).
Thanks in advance for any info.
