I've been messing around with using OBS and emulators on my laptop to capture video and stream on Twitch (Controlissues is Twitch name). Here's a video I made of me playing the first level of Gradius III for the SNES. Played via RetroArch, using a PS2 controller connected via a PS2 to USB adapter to my laptop. Recorded through OBS and made into a YouTube video. I haven't messed with this kind of stuff a lot, but I may be doing more of the same kind of thing in the future.
