Here are some photos of my 640x480p LCD displaying Mario Kart Wii both with and without the 480p fix. This is great because the 1:1 pixel output allows you to see the differences at a sub-pixel resolution.

Places to look for differences

1. e of Channel
2. inside the a of Back
3. glasses frame on my Mii
4. Ms of Main Menu

Conclusion

• fixed: graphics are pixel aligned horizontally
• original: graphics are not pixel aligned horizontally

This should at least have some explanation of what the mode parameter actually does. It would be good if there were named parameters rather than just random numbers.
