I've ported a recent recomp of GTI CLUB: Corso Italiano to Wii! 
AFAIK this is the first Wii game to support 4× SSAA ...which shouldn't technically be possible on Wii.
(SSA = supersampled antialiasing; here that means rendering at 960p and downscaling to 480p)
Please correct me if I'm mistaken and there are other games that do this!?
As well as 4× SSAA I also support 3× MSAA (the more standard Wii style of antialiasing), which has the side-effect of introducing dithering which is more accurate to how the original arcade game hardware did rendering. You can choose!
The game runs at a solid 30fps (same as the original arcade machine) which was a lot of work but totally worth it.
Currently there's around ~35% free CPU time for future use. I have plans!
I'd estimate that currently 55% of frame time is CPU work and 45% GPU work.
Busiest scene is the starting grid (lots of high detail car models), followed by some busy parts of the attract mode (multiple or close-up car models, and the explosion).
Arcade game streamed course scenery data from fast CF card, so this version has SD card with custom prefetch and both pinned cache (cars!) and dynamic cache (everything else).
Supports 16:9 and 4:3 aspect, as well as 512×334 (0.5× arcade resolution) sitting centred with black borders in the 480p window. Plus of course Wii motion control (highly recommended!), Wii classic controller, GameCube controller, and full rumble support (full, mild, off).
I'm still working on it and I'm hoping to release it between now and Christmas.
Setup:
I'm currently deep in an entirely new "Mission Mode", with a built in editor, and several other new features. Sneak peek:
I'm also using state-of-the-art (I mean those invented after the Wii) downsampling techniques for the 4× SSAA, here they are:

Setup:
- My original launch Wii
- HDMI dongle
- Genki ShadowCast HDMI to USB-C capture
- USB-C capture viewer (Porthole, my own app; supports aspect ratio, sound, recording, freeze frame, etc)
- Dolphin emulator
- devkitPPC
- HBC (wiiload)
- some custom helper apps on Wii and Mac
