feos: Trimmed empty input at the end and cleared the branch, since it's implied.
feos: Just like with #7847: Sonic123TTSLives's Genesis Sonic The Hackable "any%" in 08:53.87, optimization in this run is lacking. I made a dirty test TAS of this hack, which spawns the boss 376 gameplay frames sooner than this submission does, even though I've never TASed Sonic in my life. I had no idea what I was doing, so there's definitely a ton of room for further improvements. Here's a comparison encode:
While it is indeed preferred that hacks with new levels are TASed, this one is really just an unfinished demo with only one level, and it seems to only be known to those familiar with the Sonic Hacking Contest scene.
Just like people said in this hack's feedback, it has great potential, but it's still very obscure and incomplete. I'd recommend TASing something finished and better known to the general public instead.
Took a bit of digging and found that this was part of the 2020 Sonic Hacking Contest. The page for the entry states that it was indeed a demo. I haven't seen any updated versions out there in the wild.
