Author's comments and explanations:
Edit: cancelled the movie because of new improvements based on Aglar's trick.

This movie improves the previously published movie ([1865] NES David Crane's A Boy and His Blob: Trouble on Blobolonia (USA) by Kyman, SilentSlayers & Aglar in 01:41.73) by 1212 frames thanks to 2 route changes and new tricks to improve furthermore.

Game objectives

  • Emulator used: FCEUX 2.2.2
  • Uses heavy glitches

Tricks used/optimized

This movie's route first created by Zephyrz, who later improved it furthermore. Later, MESHUGGAH optimized it to death, recreated the same strategy with properly controlling speed from the start and used the OoB much cooler.

Blob Out of Bounds with jellybean
Use Punch jellybean on the right side of the screen with at least 235 X pos for blob and 234 X pos for boy and hold left once an additional jellybean goes offscreen (triggering the camera to go to the next scene on the right) while the boy falls down to the hole (blob).

Blob Out of Bounds without jellybean
The same setup but with 245 X pos for blob, press right once you fall down the hole and then left. This way you also get a higher starting speed (32) instead of the previous one (24).

X Speed
To reach fastest speed as fast as possible, you press R*8, empty, R*7, empty, R*3, empty, R. Subpixels alters your speed timer.

Trampoline Y speed
Checks U button every 3rd frame, stops when pressing B. The optimal length is pressing B as soon as possible and minimizing the length of U's.

Possible improvements / the route

I've tried different routes (rocket to left, run right, oob, run right from "credits" to "game end" screen and try spamming apples), but there doesn't seems to be a faster way than what this TAS currently does:
  • root beer jellybean to travel to left over the house
  • ketchup jellybean to throw blob to the right side of the screen 245 X pos
  • punch jellybean for hole then gotta go fast left throwing ketchup jellybean to cage (151 X pos)
  • ketchup jellybean in mid air and punch jellybean to escape the room and reinitalize the screen (go out and in for rat king)
  • ketchup jellybean, punch jellybean, move to next screen
  • ketchup jellybean, punch jellybean to 245 X pos right side of the next screen
  • final run for ketchup jellybean, apple jellybean ending.

Authors' comment

Zephyrz: This was the first game I ever speedran in real time, so I thought it would be appropriate for it to be the first game I complete a TAS of. With the new OoB glitch I really wanted to see how much time it saved on the TAS level, and thought I did well with my initial run; however, that's when MESHUGGAH got a hold of it. He came along and cut it down with optimizations to what you see here today and I honestly couldn't be happier.

I wanna give a huge thanks to MESHUGGAH for teaching me a couple of things about the game and optimizing it passed the point I thought was possible. Also for giving me the opportunity to be a coauthor.

Also shoutouts to the Blob community for pushing the real time run down to pretty close to the TAS and keeping the game at least a little alive.

Blob is love.

=== GAME OVER ===
MESHUGGAH: See you until my next TAS =)
