So, I've been doing some thinking about how to add the Atari 8 bit computer software, and I think I've come up with a solution. It would require 3 different categories, because as it has been mentioned, games were available on cartridges, floppy disks, and cassette tapes. I'm not sure if there were any regional variations, but if we created the following categories, it should suffice for now.
Atari 8-Bit Computer (Cartridges)
Atari 8-Bit Computer (Floppy Disks)
Atari 8-Bit Computer (Cassette Tapes)
