I'm not sure if this is the right place, but since this is a sticky regarding the submission process, here it goes.
I was wondering what the rules are regarding improvements on an existing movie? I'm more of a speedrunner than a TASer, but I've found a few improvements on an existing TAS for a game that I speedrun (the improvements are of the routing and game mechanics nature, as opposed to "execution"). The game is for NES, so I know how to use the FCEUX TAS editor well enough. Also, I have most of the relevant RAM addresses, so I could theoretically create my own movie from scratch.
However, that would take a lot of time, and I'm not sure if it's required. Also, I'm mainly interested in speed rather than adding any "entertainment", so any brand-new video I made might be boring.
I've already managed to improve the movie by 18 frames, and there may be more on the way. It's a rather small amount, I know, but considering that the Super Mario Bros. TAS
(with Warps) was improved by a single frame by HappyLee (and the obsoleted movie was by someone else), I can see that small improvements may be relevant.
Anyway, considering that a majority of the inputs in "my" video will be the work of someone else, I have no problem seeing it listed under their username or whatever (though I would hope to have my name mentioned :-P). But as a newbie here, I just have no idea what the protocol for such a thing would be?
Thanks in advance. :)
(And of course, I would have no problem contacting the original submitter if it becomes relevant. In fact, I've PMed with him once before, although it was in regards to my speedruns of the game as opposed to TASing.)
