There are specific ways to get sets on archive. look for a gameset but search “no intro” – remember the U.S. vs international sets. A Japan set of Famicom or Super Famicom will yield more / different titles than just Super Nintendo.

Also note that arcade sets can require to be paired with a specific MAME emulator version. So look for those pairings and make sure the emulator is set in your game machine.
