Bruh it automatically changes O.D.W to o.D.W when you type it
For setting this up, you want something that can stream your phone inputs on a PC and just use OBS. I'd recommend just settings up homebrew and NTR CFW though, lets your stream any 3DS game for free. If you ever decide to do that, here's an up-to-date guide: https://3ds.hacks.guide/
Also being on the actual wii just makes it a bit harder to cheat (not really that insanely difficult). If you have money to spend it becomes even easier too. That being said dolphin is obviously easier, but not really by that much.
@Komrade Could be, however it'd still make it easier (obviously not guaranteed) to detect TAS-like inputs without having the runner doing some either costly or weird stuff
@Lieutenant_Boo , @Oreo321 what if the description says something like 'this run might not be a WR'? Or would that not be the same? Genuinely curious
