There are no other mentions of these on the Web or in Supermodel source code. Will try though. Perhaps the interactive config will work with my current version of the emulators
Am having the same "problem", though it shouldn't be an issue at all, as there's nothing special about those keys. I use them in my IPacs for all sorts of other emulators. It's been years, but as I recall, the "standard" MAME keys for P1 include some that cannot be used for HyperSpin menu navigation (LAlt comes to mind). Nothing stupid about any of it and I'd be shocked if Supermodel can't handle these keys.
EDIT: Supermodel configuration confirms you are correct, sir! No idea how that string does not exist in the source, perhaps it uses a third-party library for this stuff?
Thanks!
EDIT:
Supermodel is using SDL tokens, as documented here:
