By officially I mean officially supported by Sony.

Hi, so I've heard it's officially possible to use a PS3 controller on a PSP Go and I read there's no input lag at all.

Would it be allowed in speedruns?

I don't have much knowledge on PSP systems so I could always be wrong.

These days getting a capture card or some way to record is not difficult, to be honest it wasn't even 8 years ago.

I do think a run must be verified before adding the time to the leaderboard, otherwise anyone could say "hey I beat WR today".

Anyway, streaming on the other hand is not accessible to everyone due to slow internet speeds, so at least in another decade unless it's a top run it shouldn't be a requirement.

From my perspective, I would run only a game for fun and to keep the chat hyped so I would never do anything offstream, and most of the times I can't stream either. https://pbs.twimg.com/media/CQgBatAWUAAaDh7.png:large
