As an SM hacker myself, I'm always glad to see these being done. I will note right off the bat, however, that this desyncs for me shortly after boost ball is acquired (about 1/5th of the way through the run by frame count).
Whether or not it's publishing material, however, is a totally different discussion. Like Derakon said, breaking down the differences is really important if you're going to submit this. And, like Derakon said, I'm fairly certain that there are other hacks more likely to get published than this one if runs were done (not to say they're a shoe-in, either).
If anyone wants to see what this hack looks like, a quick YouTube search of "Angry Fire Chozo" gave me
this along with some others. (Note the TAS submitted is not the same as the one in this link!)
I do feel this is one of the better SM hacks out there, but that's not really as nice a compliment as it sounds (most hacks are terrible for any game, and SM is no exception). I have played and beaten AFC, and in the world of SM hacks it's notable, but it is not necessarily an entertaining TAS choice, simply because most of the sequence breaks and general play is not going to make sense to anyone who has not played it. This is not a major issue in games (I can enjoy TASes of games I've not played), but in hacks, it becomes a more pressing problem because it is harder to differentiate between native gameplay and modified gameplay if you are not familiar with the game. When you can watch a TAS of a hack but not understand what's impressive about it, you're possibly looking at a poor choice for publication.
Again, I am glad to see that hacks are being TASed... I'd like to see more. But I do not think that this particular hack is a great choice for submission. I would agree with Derakon that there are better choices out there (Eris, Eris, Eris!) that viewers can enjoy without playing through on their own.
