It's interesting to me how the SNES is in a spot where even the cheapest flashcarts (that I've seen) support bigger ROMs than any licensed games used, but there's a big price gap between those flashcarts and ones that support coprocessors.
So if you want to support the basic ones (and I do) then you trade away the kinds of expansions games back then could have, and get a new one in return that couldn't have been explored that well originally because it would've been too expensive.
@NovaSquirrel Yeah, I imagine there'd be a lot of things you could do with that much space, and it'd be especially a boon for something like an RPG or other more graphics/dialogue, less gameplay-intensive titles
