I’m not sure how much impact the texture have on running the game, but the original ran better than the Wii U remaster.
Presumably, NVIDIA’s emulator is for both Wii and GCN games as it seems like TP is from the GameCube release but there are also Wii games.
This opens the door for a lot of games to come over:
Luigi’s Mansion didn’t get a switch port. Cleaned up texture and 1080p output would be really nice for that.
Mario Sunshine hasn’t been made available in awhile, not sure if that game has issues with textures but it could still clean up.
Issue would be with the Zeldas. TPHD can take it or leave it, doesn’t change too much and this could look nicer.
WWHD should probably get a port, tho.
Biggest issue would be Skyward Sword. It needs some major updates, I think. Not sure messing with an emulated version would be the best way of handling that.
The N64 games are a curious case, they upped the polygon count, look and play better too.
Guess Grezzo Can port them? Cleaning the textures up would help quite a bit too.
But, depending on what Nintendo could do they could branch out to 3DS games as well.
Kid Icarus with deep learning AI textures would likely look quite nice.
