Maybe and maybe not. The one deficiency of the N64 outside of the cartridge was that it was not made for handing 2D art and sprites, it's a polygon pusher, and in tandem it had an overly low memory buffer to store data as well. The buffer wasn't as big an issue for 3D as much of it is just textures on polygonal structures, but when you get into a full 2D experience you have to account for every background layer, every sprite, all of it. A big reason you didn't see 2D games on N64 was that it wasn't easy enough to do unless it was something more on a basic side like Namco Museum. A few tried it, but not many, yet the only one who did it successfully with good amounts of stuff going on was Treasure with Mischief Makers and Bakaretsu Muteki Bangaioh. Obviously the N64 would do better than the SNES allowed with SFAlpha 2, but how much better I don't know where issues would have popped up. In reality it could have been the crappiest box to shove stuff to to where the point the PSX stuff was acceptable to people.
