I would use my normal Wii but

1. I use the USB Loader so it wouldn't matter anyway
2. My Elgato capture card doesnt capture audio

So I have to use an emulator. But am I allowed to use any widescreen hacks and hd textures...

I'm not sure if that's ok.

When are you supposed to start a run for a specific level? The rules are confusing me. It says nothing about when to start the run.

Edit: I’m big dumb for forgetting that USB loader is banned! I play most of my Wii games via a USB Hard-drive with over 200 games. That includes NSMBW, but I'm not sure which category I should submit my runs in (If I do start speedrunning this game that is), physical or digital. If I had to guess, I think it would be digital. Can someone please tell me which category it is?
