First Flash submission! Meat Boy is a classic game that spawned a whole series of hardcore 2D platformers. In this run I complete the lowest amount of required levels to reach the credits.

Game objectives

  • Emulator used: Ruffle (nightly build from 26/01/2022, though newer should work fine)
  • Aims for fastest completion


This TAS was made by runnning Ruffle, a flash emulator that runs well in Linux, in combination with libTAS. Since a couple months ago, this is the go-to way to TAS Flash games.
Since the game does not require all levels to be completed and levels unlock a couple at a time, I can simply quit to menu to skip slower levels and only do the minimum required to reach the credits. This also allows me to skip all the cutscenes that usually play at the beginning of worlds. In the run I follow the RTA route, detailed here.
At the beginning of each level Meatboy has a couple frames of invulnerability, which I use in level 7 of chapter 2 to run through a fire straight to Bandage Girl and skip all the platforming usually necessary. I also abuse this mechanic in a couple levels in chapter 3 to jump off lava.
Cycle-based obstacles appear to have some kind of RNG to them, randomly activating earlier or later from the moment Meatboy appears in the level. These cycles actually changed in libTAS 1.4.3, causing me to have to redo some levels and some of them actually being slower because of it. The youtube video linked is actually slightly different from the movie file submitted, as that encode was done on 1.4.2 with different RNG. Overall compared to the previous encode, this movie loses a couple frames due to this RNG change.

slamo: Claiming for judging.
slamo: It's the first Ruffle submission! The staff had a brief discussion and the decision to start accepting these was not controversial. They sync pretty easily and they use libTAS, an emulator we're already familiar with, so why not? We have already been dealing with nightly builds of Dolphin, so using nightly builds of Ruffle is not that much of a stretch (and they all seem pretty stable anyway). We have come up with some guidelines here.
Great choice for the first game as well, the optimization looks fine and it beats all known records. Accepting!

Oh god, that old 5 seconds Newgrounds audio loop. Simply epic. I'm so glad Flash still lives and can be TASed now through libtas + ruffle. Also the TAS was pretty good yea.

Syncs for me as well, though I had to substitute "-g gl" for "-g vulkan", as I'd get the following otherwise:

Not sure what's up with that.

Caution: You are reading a post by the notoriously unimportant GamesFan2000. Reader's discretion is advised. Looks like 3DS won't be the only platform joining the ranks of TASVideos in 2022, as Adobe Flash is also making its debut. And the first Flash submission is a game straight from the Flash Hall of Fame, the one and only Meat Boy. Truth be told, I didn't even know this game existed even back when Flash was all the rage. I wouldn't blame anyone in the same boat either, because the sequel, legendary Indie Hall of Fame inductee Super Meat Boy, damn near erased it from history due to being much more polished and reaching a larger audience through being published on XBLA and numerous ports to later systems. This is really the first time I've seen any gameplay from Meat Boy, so I am completely unqualified to say anything constructive. The encode shown is very impressive, and while it's slightly outdated, there's only a few frames difference with the one that was actually being submitted. This is a yes vote in spades.
