Out of the box, the Wii has 4:3 mode and 16:9 mode and these can be switched between in the settings. My issue with this was always that most GC games are in 4:3 and so if I wanted them to look right on my Wii (which is attached to a wide screen) I'd have to manually go into the Wii settings...
I am trying to hack Fire Emblem Warriors on my 2DS XL, I have been trying to get it to work, but I need some extra help figuring it out. I have HEX codes, and a possibly outdated plugin, but I dont know how to implement them
