Welcome!
Here on this channel I upload video game music but with added video of the area where the track can be heard in-game, in addition to ambience. Uploading full OST's in this style is hard, so my uploads will tend to be random mostly. Hope you enjoy!
Wondering how I make these? Here are guides I found helpful.
wiki.dolphin-emu.org/index.php?title=Free_Look (For using freecam in dolphin)
youtu.be/Ehk7Xpxy100 (For making UI's invisible, replace the image with a small 1 pixel transparent png)
I can't answer every technical question but I hope this helps some of you!
