Comments

Everything about the glitch that triggers the credits, done via item swapping a Chuck by collecting and licking a coin at the same time, is described in the submission text of the previous movie. Thus, I'll describe here just the improvement itself. Instead of eating the green shell right after spitting out the fireballs, I kicked it forwards by touching it while Yoshi is ascending. So, it's possible to spit out the fireballs much further before getting the green shell. This initially was saving 4 frames, but after a while it was possible to save 8.
Amaraticando, then, managed to save an extra frame, by spitting out the shell while Yoshi is turning right. That, however, was preventing us to get the credits, because the controller #1 register ($4219), which allows us to trigger credits with input, wasn't being executed. We investigated a lot what was causing it, and it turned out it was Mario's position. At frame 2510, $4219 is not executed if Mario's x position is 2470 or higher, in this situation. Therefore, we have to press X and left at the very end, before the game end input. The last inputs that trigger the credits were done by Masterjun.
Update: The berry, placed where we needed to be to get the green shell, was stopping Mario for a while. Berries freeze Mario's position a bit when Yoshi eats them with his mouth, but the rest of the game keeps moving (such as the fireballs). Avoiding it, however, seemed to be impossible, because we had to press < to not destroy the shell, and that makes Yoshi to turn around and eat it. The solution was to turn left before, and then turn right at the very moment we spit out the flames. While Yoshi is turning right, pressing < doesn't make him to turn left. This way, we could spit out the flames even further, since it's easier to catch them up without the berry disturbing us.
There's a frame rule that affect the fireballs: they can turn enemies into coins only in 1 frame out of 4. And this frame rule was horrible to us, because we would need to eat the coin at the same frame it turns into a coin, which means it is still moving with the shell's speed, which is too high. It was obligating us to dismount Yoshi only in the upper platform, but that, again, was preventing $4219 to be executed. The solution was to spit out the flames much below, and spit the shell at a very high position, so that it takes 4 extra frames to be burned. In this 4 frames we spit out Yoshi's tongue and dismount it in a proper position, and both Mario and Yoshi's tongue reach the coin at the same time.

Noxxa: Judging.
Noxxa: Replaced with a 1 frame improvement.
Noxxa: Accepting as an improvement to the published movie.

Voting yes! Even though it's a little improvement, I think a improvement on a Game and Glitch category is necessary to be close to perfect, always.

How hard would it be to do this on a console? Is there maybe an alternative setup that requires less precision?

Credits jump has been done on console, using pixel-perfect sprite positions to spell out code rather than mashing it through controller inputs. It's still very hard to do though. On mobile so can't provide a link right now unfortunately, but it shouldn't take long at all to look up a video & explanation.

The previous version of this video did not verify. I can try this version though, give me a couple weeks to unpack and decompress from this convention.

Nice improvement! I like to see such a strategy which is easy to do but not so obvious to think up. Voted yes.

Amazed at very cool improvement;-) I'm impressed with the elaborate works for saving frames. Yes vote for your challenge!

A slightly different strategy, which will be described in the submission text, allowed us to save another frame. I've uploaded the movie to the userfiles, here is the link: http://tasvideos.org/userfiles/info/24824444132533782 Mothrayas, could you replace the movie by the new one, please?

Done.
http://www.youtube.com/Noxxa <dwangoAC> This is a TAS (...). Not suitable for all audiences. May cause undesirable side-effects. May contain emulator abuse. Emulator may be abusive. This product contains glitches known to the state of California to cause egg defects. <Masterjun> I'm just a guy arranging bits in a sequence which could potentially amuse other people looking at these bits <adelikat> In Oregon Trail, I sacrificed my own family to save time. In Star trek, I killed helpless comrades in escape pods to save time. Here, I kill my allies to save time. I think I need help.

The last time I checked on this game being glitched it was like 2 minutes long. Didn't realise it gt refined so well. The actual video doesn't look too strange compared to the first glitched ending so it makes it look like very little set-up is actually needed to glitch the game now. Which is strange.
Enjoys speedruns but hasn't actually tried making any yet.

Hello everyone, A few months ago, DwangoAC and micro500 were able to play this run back on actual hardware using the TASLink replay device. However, the run had never worked for me on my SNES, SMW cart, and TASLink replay device. The only notable difference is that my cart is a 1.1 whereas they were both using 1.0 carts. Every other ACE/TAS I have attempted with SMW works great though. Ilari suggested that SRAM[0x101] == $700101 == 0xFF in order for the payload to work properly. This is indeded the case in lsnes. However, today I installed the SMW "jailbreak" to view my memory and noted that the memory address read 0x00 for me rather than 0xFF. After manually modifying $700101 to read 0xFF, this game end glitch worked flawlessly on my hardware. My question is: is this due to my having a 1.1 cart, or did my cart's SRAM get corrupted somehow? Thanks, Owna

Neither of those. This is simply due to your SRAM address $0101 having a value of 0x00 instead of the required 0xFF of this run. In this run, that SRAM address is never touched so it stays whatever it was.
Warning: Might glitch to credits I will finish this ACE soon as possible (or will I?)

Thanks for your reply, Masterjun. It seems that if the user has ever used file B, that address will not contain 0xFF. So I wonder -- do we consider this run console verified if it requires a particular initial SRAM state?
