the greatest disappointment of my life was learning that "gba-enhanced" game boy games, that did cool extra shit when you played them in a gba, aren't actually using any of the enhanced processing power or whatever. they can't, in fact, it's completely unavailable to them. all they're doing is detecting the gba and turning on some content that would have worked on the game boy just fine, like you can romhack it into working flawlessly on a game boy
