So, i want to start streaming my mario 64 runs, I play the game on N64 with a crt tv, and i use a gvusb and cable splitter to have the gameplay on my pc, which i then stream, however my crt emits a high-pitched sound that is picked up by my mic, and i wanted to know if there was a way for me to keep my mic from picking up the high pitched feedback from the tv?

any help would be greatly appreciated, thank you

Am I allowed to use a Retro Fighters Brawler64 wired controller on N64? If not, what other third party controllers are allowed?

I have looked up various ways to record N64 gameplay, and they all say to buy 3 separate 2 female to 1 male splitters. What I don't understand is why I don't just buy 2 male to 1 female splitters, and plugging in one set of cables to my crt, and the other set into the GV-USB2, which would then go into my computer. Does this combination of cables work? To my understanding if I used 2 female to 1 male splitters, I would also have to buy male to male cables to run gameplay to my CRT as well, can that not be skipped by just buying a 2 male to 1 female splitter? I am genuinely very confused and any clarification on this subject would be greatly appreciated, thank you.
