I think this might be a bug, please feel free to correct me if I am missing something.
The problem is that the miss list shows missing sets when sample sets have no corresponding rom set.
You are missing 1 of 8734 known MAME v0.138 sets (+ BIOS sets)
alphamc07
Steps to reproduce:
Create dat file from mame.exe (mame0138b.exe downloaded from
http://mamedev.org)
"OK to all" when prompted "Missing Alternative Samplefolder will be added as sample-only set."
"No to all" when prompted "Press yes to remove parent/clone relationship or no to force split-merge mode."
"No to all" when prompted "Insert found checksum instead of using the 'nodump'?"
Add rom path for roms
Add rom path for chds
Add sample path for samples
Scan with sets, roms, samples and chds selected, all "check" categories selected, no "fix" categories selected
Results window is empty
Statistics window shows:
