Me and my Stream crew had just finished using 1964 to stream Ocarina of Time without any major video issues.  I am also able to use VGA for Fire Emblem also no issues (aside from pausing when you tab out). Now when I try to play Majora's Mask on the stream i have 2 issues.  Mupen64 runs just fine on my screen, no issues there, music plays everythings good.  Except for the game capture.  What everyone else gets to see is the lovely vizzed.com loading screen, instead of the actual game, no matter how many times I reload or restart.  I then go to good 'ole 1964 hoping for an easy fix..but I was wrong.  As it lists, it has graphical issues...so the game takes idk 4 times longer to load, but is the only one of the two versions that shows twitch what I am watching.  Essentially, I can't stream the game without either letting them hear and watch my reaction to the game, or watching a really lagged version of the game.  I need some help guys, as most of my small fanbase prefers watching me play Zelda, and we had plans to go right into Majora before going to the other games on the site.  

thank you for any advice you are able to give

If you do a region capture, you should be able to record/stream.

At some point, an update broke OBS and made it so the game stream doesn't work anymore with a lot of the RGR games.

yeah.. about that, I am window recording, and even region recording does the same thing.  the only way I can get the game video to work..is by using monitor capture.  on the one screen.. if I do window/region record it just shows the vizzed game loading screen you usually get while playing a game, but it never shows the rest of the game.  If I use Game Stream, you are right it is broken, all i get is a black screen.
