GoodMerge
Good Utility in Multi-System CategoryGoodMerge is the ultimate space-saving companion tool to Cowering's Good ROM Renamer suite. It takes a ROM image collection (raw or compressed) and a "*Have.txt" file and produces a number of 7Z, RAR, Ace, or Zip archives with all the files associated with a particular game stored in one file. Now with a new improved GUI.
