(I did more reading into PAL/NSTC and analogue-digital, but still I didn't get to the bottom, I'll do more searching on the forums, maybe Wii/GC games render at lower and upscale originally?)
The EFB (embedded frame buffer) in the GC/Wii GPU is 640x528, which means that the maximum size a game can render at is 640x528 (but it can choose a smaller size if it wants to). This is regardless of NTSC/PAL and everything else.
