In September 2025 I completed the First-Ever Full-Game Cuphead TAS. This video serves as a bit of a Behind-The-Scenes going over why it took 8 years since the game's original release to make one, what finally made it possible, what the TAS-making process looked like, and what future Cuphead TASes I might work on.
Edited by @Storster .
If you want to run this TAS yourself, I've put the input file and the modified code here. I might make a proper tutorial on how to use libTAS for Cuphead eventually, but the gist of it is that you need the unofficial Linux port, you need to replace Cuphead_Data/Managed/Assembly-CSharp.dll with one of the two I've provided, and then run it with the input file: github.com/SBDWolf/TAS-input-files/tree/main/Cuphead
To make the linux port, convert the MacOS version to Linux using this program: github.com/DemoJameson/Cuphead.macOStoLinux
Music Used:
Cuphead - Carnival Kerfuffle
Cuphead - Botanic Panic
Cuphead - Forest Follies
Cuphead - Inkwell Isle 1
Cuphead - Junkyard Jive
Cuphead - Aviary Action
Cuphead - Treetop Trouble
Cuphead - Funhouse Frazzle
Cuphead - Floral Fury
Cuphead - Sugarland Shimmy

Ive been working on this game for a while. To my knowledge Im the first one to run this game version. It was really fun to find new tricks in an unexplored game and to route the run from start to finish, with the only help being an unfinished TAS of the Sega Genesis version (which, as of yet, also has no completed RTA speedruns of), and it was especially an honor since this was one of my favorite games from my childhood.
Fairly happy with the run. Some hiccups in a few places (especially in The Realm of the Dead), but this run also includes the best level 5 boss (the frog) Ive ever had and thanks to it I snagged the first sub-17 run. I will probably keep going for a bit of a lower time still.
I used JoyToKey to be able to properly use a controller. The game does have native controller support but it only supports the analog stick and not the dpad. I hate using an analog stick for 2d sidescrollers and I didnt want to use a keyboard either, so I took this solution instead. In the eyes of some, using a third party application to rebind controls might make a speedrun feel less legitimate but eh, this is the only way I felt like controlling the game and I dont feel like I gained any special advantages with this specific application.
And while Im at it, heres the controls Ive been using:
Morph/Ammo: Right Bumper
Attack/Shoot: X
Jump: A
Quick Morph: Left Bumper
Teleport: Y

Sub 31! The time could be pushed much lower but Ill put it on hold for now since this category is very reset-heavy on Ribby and Croaks thanks to the new discoveries.
(I know the layout says All Bosses No Major Glitches, there were supposed to be some category changes that ended up going in a different direction)

Still lots of time saves. Got a 1:00 Hilda (+4), 0:33 Grim (+4), 0:33 Rumor (Why did I have to choke the one-cycle, +5), 1:31 King Dice (+5), 0:45 Devil (thanks spider, +7), plus a few minor time losses (I guess I lost 4 extra seconds on Ribby and Croaks over the extremely difficult super skip but I hardly can complain about that fight). Highlight of the run was Baroness Von Bon Bon with a near-perfect fight and a time of 0:28.

Jump: Right Bumper

Lots of bad fights: 1:02 Hilda, 0:36 Baroness, 0:41 Wally, 0:37 Rumor. On the other hand I also had a number of great fights (0:30 Beppi, 0:39 Cala, 0:43 Devil and my first ever 1:27 King Dice). Sub 24 is closer than ever!
Still salty about that accidental parry on Beppi though

Didnt go for Hilda Glitch, a few rough splits but a solid deathless run nonetheless. Ill leave this time be for now to focus on Regular mode.
Apologies for no webcam and a worse microphone. I dont have access to better equipment currently, I will be back with my old setup soon enough.
