Thanks, but I've tried what you suggest. That's the problem, the folder in which I place the games doesn't show up when I click on "add game" in ScummVm. I see folders, but only ones that are the OS linux system folders. (And I can't figure out how to place the game/s into those system folders).
But it sounds like from your reply that Scumm should(!) see the folders I create on the memory cards, and into which I've placed the game files. All of which makes me wonder if the problem might be the wrong file extensions on the games (or similar issue)? But I'm using the same game files that my PC version of Scumm DOES see without any problem. I don't suppose one has to set some sort of path command?
Aggh.
