Sorry about that… midnight editing moment

Hey so, I just got a new PB in botw and it’s my first time uploading a speedrun and it says that you can’t use emulators so I searched up why and it said because some give less lag and stuff. It also said that some emulators are ok to use so I was wondering if it is ok for me to use the Cemu wii u emulator for a botw GP any% speedrun? Thanks for the help!

Also if this one isn't allowed can I get a exclamation to why emulators are banned...(just curious) thanks!
