Emulators do often have that option, but many games rely on the 8 sprite limit to hide stuff too. Depends what games you want to play but it makes many of them worse because of that.
With YouTube you will just have to expect that a significant amount of people (probably the majority) will be watching in 30fps, whether or not you uploaded at 60fps. There's really nothing you can do to change that reality.
With Twitch there's similar problems but here's an example
where despite broadcasting from OBS at 60fps it was not capable of syncing with the emulator and you get a very erratic effect. That's very common, really, and people often use OBS to capture video for non-streaming stuff like YouTube uploads too.
It might technically be possible to capture it cleanly from OBS with very careful settings, but basically nobody is going to figure that out. Even people who stream for a living have this problem all the time with NES / retro games that do alternating frame effects. (...and of course, a lot of people are going to be watching it at 30fps anyway, whether or not you got the source version right.)
Anyway, maybe easier to just decide this is an acceptable problem and ignore it, like some people are suggesting, but to me it's worth considering.
Curiously, I was looking at a few older games just for examples and discovered several commercial era NES game that uses 30Hz alternation when you take damage instead of 60Hz, including Super Mario Bros. 3 and Mega Man 2. I don't think they were able to see the future of YouTube and streaming, but I think probably they thought 60 didn't look flickery enough
to communicate the effect so they inentionally slowed it down.
SMB2 has an interesting progression from 15Hz to 30Hz to 60Hz when you take damage, indicating roughly how close you are to regaining solidity. Swamp Thing goes as low as 7.5Hz on damage!
