Hi community!

(Sorry if this question is already answered elsewhere, but I really couldn't find an answer while googling, so I hope you can help me!)

I'm new to the speedrun community and I'm already excited to submit some runs! But before I start running I rather inform myself if my runs would be "legal", because I'm using different equipment.

Out original Nintendo Wii remotes broke in time so we bought cheaper ones which aren't original Nintendo Wii remotes. My question is: Are they allowed? Or do I need original ones? Here's an example: https://www.amazon.de/TOOGOO-Fernbedienung-MOTION-INTEGRIERT-Weiss/dp/B01IH03CA4/ref=sr_1_8?__mk_de_DE=%C3%85M%C3%85%C5%BD%C3%95%C3%91&keywords=wii+fernbedienung&qid=1554911051&s=gateway&sr=8-8

Also my dad modified our Wii years ago. I can't even remember what he did with it but it doesn't affect gameplay or something like that. Is this allowed or do I need a new "vanilla" Wii? Because if that's the case, that would be a problem because I want to run some games from the e-shop, but they already shut down.

Thank you very much for your answers in advance! Timo
