Vinny Mainolfi provided this info on the fb group page regarding how to make your own multi-game disks. While I disagree with his assertion on not using a basic save state (it will work, if you run avenger or alleykat prior to making the save state), it's not worth harping on about. End-user can decide on this choice themselves:
Vinny:
Something NEW regarding the Multi Disks… some people are getting the FILE NOT FOUND error when trying to load the disks? This is because they are using a GAME SAVE that already has the LOAD“*”,8,1 typed out. You can't do that. When loading a new Multi Disk, you've GOT to load AlleyKat from the built-in games, go back to the menu and select BASIC, then you've GOT to type LOAD“*”,8,1 for the first time that you use that disk. Don't use the lazy way of a GAME SAVE. Does that make sense?
