I am new to speedrunning, so I would really appreciate it if someone can give me a detailed walkthrough of how to setup GV-USB2 for the Wii. Also, I know this may be a dumb question, but when people speedrun, they are playing the game on their TVs and it is being streamed simultaneously on their computers, right? Thanks

definitely join the discord, you'd get a much better answer there than using the threads on speedrun.com the discord can be found under the "Follow" button near the top of the page
