Well...rezipping files is a 1-line batch file...


What you have to care for when using not-zipped sets is, how they are listed in the datfile.
ClrMamePro allows the following scanmodes:
[rompath]\[setname]\[rom 1 ... rom n]
[rompath]\[setname].zip

So be aware that using unzipped sets, they all need their belonging setfolder and check which setfolder is used by looking at the datfile.
