Ultrawide AR codes not working

I see images here showing it working:

I found these instructions:

https://forums.dolphin-emu.org/Thread-gc-ar-codes-for-16-9-21-9-60hz

The links are multiple years old. I am not sure if they would still work on Dolphin 5.0? If I google wave race blue storm ultrawide I can varying instructions about enabling or disabling the widescreen hack, enabling/disabling the force aspect ratio 16:9 or stretching the image. I have tried all the configurations that I could try and I always get a chunky stretched ultrawide image. I dumped the AR codes in the properties of the wave race game, but I have no idea if they are taking effect or not.

Are there any updated instructions? I feel like I am blindly stabbing in the dark.

I figured out why it was not working. I did not have cheats enabled so the AR codes were ignored! It works and it looks amazing! Definitely the best way to play my old games!
