The name explains it.
(By the way this was also a challenge for myself. I did not use the TAS editor to make this at all. All of this was made via save-states and real-time, with a bit of frame-advancing. Normally I just click on the TAS editor for the entire run, which is very painstaking.)
Also, if I get better at TASing this game, I will attempt a "No Going Into The Castle" TAS.(It is impossible to skip the castle theme in 8-1 and 8-3.

1-2 warpzone to 4-1, 4-2 warp zone to 8-1? :)
I know of no other route.

By "Castle Theme" I mean the music that plays after you beat a level by grabbing the flagpole. This was a proof of concept about a simple and useless way to skip the "level end" cutscene. I didn't do world 8 because it is completely impossible to skip the level end theme in those levels.

Not only did they crash the game, they optimized it so much that the rerecord count overflowed.

I decided to console verify the run. The main reason was because the audio does not freeze and play forever at the end of the run and instead just makes a nice elevator ding sound.

Nope, I have to come clean: I edited the rerecord count before uploading it.

Don't worry, it was obvious that you edited it. I suspect that it might not even be possible to overflow the rerecord count lol.

This crash seems like potentially a big deal? I wasn't aware that any bugs of this nature existed in SMB1. Could it be possible to get control over PC, or write to a controlled address somewhere? Has anyone run this in a debugger to find out what's happening?
I did a quick search to see if something like this was already known. I found Super Mario Bros. 2 (FDS) - World 8 Crash Gltich from 2018, but it looks a little different: a wind-assisted clip into entering a pipe backwards (looking a bit like the SMB3 7-1 wrong warp).
EDIT: I see there is some discussion beginning at forum/p/504862#504862. HappyLee has a demonstration video with a similar activation sequence ("it involves double stomping the Koopas and breaking a brick that has a coin on it") at userfiles/info/63142191243839512 and https://www.youtube.com/watch?v=rA-JeFTtglo.

I was once able to talk to HappyLee, he thinks it might not be possible to do anything interesting, but I decided to investigate further. There are still so many things I don't know.

Can anyone improve the time? I think my execution might not have been optimal.

After getting the mushroom, what do you do? I'd like to try improving it, but I am blind, so I don't know what you do.

I have no idea how you can TAS without being able to see, but you go forwards, over a few pillars until you reach the part where there are two koopas going left. You wait a bit, get a slight bounce off the first koopa, bounce off the second koopa while kicking the first koopa to the side, and immediately destroy a brick block with a coin on top with Mario's head. You'll have to try this a lot of times to actually get it to crash, since the exact reason it does so doesn't seem to be documented.

If you make Mario collect too many coins too fast by making him stand in a tile that was frozen to C2(a coin) in the hex editor, weird things happen. This is an example. Please use with $05F5 frozen to C2. Please help me explain why these glitches happen and whether similar results can be reached without cheats.

Is there a known game genie code for this?

It's been more than a year, but I'll look into a code that does something similar. I'll post it here when I find it.
