I need some help with this one as it is really frustrating me ray: I have a complete ROM set of GoodSnes 2.04. I want to copy these on an SD Card for use with a Super Everdrive, but obviously I only need 1 copy of each ROM for every game (don't need duplicates). I am using GoodMerge to remave the duplicate files for me but everytime I hit MERGE I get the error "YOU MUST SELECT A ROM SET". What is exactly GoodMerge looking for? I assume for goodsnes.db? I have double checked all my folder paths, and these look fine :shrug: Any help is appreciated.
