Shot in the dark: I remember, at some point, there being a Github repo which contained a series of patches to fix the Supervision 110-in-1 ROM, which was known to be a very broken dump. Now, I just found that someone redumped that cart, and, aside from a glitch that lets you move the menu cursor out of bounds, every actual game seems to work just fine. However, I wonder if an archive of that (apparently now non-existent) repo still exists? I think it had as a goal to fully restore every game on there, including their copyright notices, and, in some cases, their title screens.
