Streaming BW has always been a pain due to the full screen color palette, necessitating windowed mode or some ugly hacks to get it working. I wrote a plugin for OBS that captures full screen BW and performs the proper palette conversions. Unfortunately it isn't perfect, for some reason the out of game palettes have incorrect values, but the in-game palettes I tested seemed fine. The cursor will also not be visible in battle.net screens.

Put it in your 32-bit OBS/plugins/ folder, a new source option called Brood War Capture should then become available. Will not work with w-mode, only normal full screen BW.
Note this isn't tested much at all and is very much still proof-of-concept stage, as I only have a single monitor to work with here it was impossible to tell if this was actually working properly. Let me know!
