I want to make a TAS but I want to know if it is allowed. I openly admit to it being a TAS but I want to know if there is like a page that has a leaderboard for TAS? Can someone help me with this please?

http://tasvideos.org/ is what youre looking for

What about games that aren’t allowed on TASVideos? Like games that are TASed using external tools, non emulation.
