But if they did that, what's the point? It's not a N64 anymore. Just an emu-box trying to make the games look different. Not that it wouldn't be an emu-box if it didn't correct anything, but if we're moving away from the original hardware and how it rendered the games, we might just as well configure an emulator to do something similar.
Either way, Nintendo doesn't give a shit. They like counting money, though. That's why they released virtual console games [ROMs] without optimizing them for PAL, which is why they ran slower. I mean, come on ... What is this? PSOne? This is how much they care. So forget about major improvements. They didn't even fix the framerate in N64 Zelda games when they released them on Gamecube. Because why bother.
