Baldi's Basics The Ultra Decompile
SOURCE CODE FOR BBTUD IS NOW AVAILABLE!
What is this decompile?
This decompile is a place with a lot of content built into the classic version of Baldi's Basics. It's like playing classic but with all of the new content around (remaining its classic style).
It's playable on all main platforms and even Android! Heck, you can even play in your browser.
What kinds of content are inside?
- A second or third floor. An elevator system.
- Adjustments you can make to spice things up.
- MULTIPLAYER! Competitive (playing as Baldi) and Cooperative (beating Baldi with other players).
- Carryovers from other Baldi's Basics games (BIRTHDAY BASH!, Camping Field Trips, etc.)
- Fresh new modes (Hide & Seek with Baldi and Multiplayer).
- Play between two schoolhouses (Classic and Grand Opening).
- 7 Unique items.
- 10 endings (Classic and Grand Opening).
- Unique and improved mechanics.
- And a lot more!
Feel free to learn more. There's a bunch of content waiting for you in this mod.
DISCLAIMER: This decompile has tons of features that separate itself from Plus. It's never intended to be the original game. Although it does have Plus items and characters, it's built through Classic with legal functions, and no core features are implemented. If there's any concern or anything not allowed in this decompile, please reach out and I'll comply.
Is this the end of the mod?
Well, yes. Since I don't plan to make any more updates, this mod has become its final state. Don't worry, this isn't really the end. You can still download the mod itself, and chat with the community.
As of now, I still plan to update the Grand Opening schoolhouse. Therefore, it hasn't reached its end yet.
Can I submit suggestions?
Since the V3 update, I won't be adding anything else therefore I will not be taking any suggestions. NO SUGGESTIONS!
However, I plan in the future to add content to the new schoolhouse.
Want to see old versions?
See old versions from here, all the way up to V3.0.1 (no crashing): UPDATED!

I had a Legendary Apple collected randomly and I used it, then came back out, STILL THERE! Until next time, IT'S GONE!
I know you won't fix this, BUT I COUNT IT AS MEGA CHEATING!

NOOOOOOOOOOOOOOOOO :( it's time...
Guys, if you're complaining about no iOS port,
Click here.
Press the Share button and Add to Home Screen to install the app. There's no difference except it's on your Home Screen and when you open it, it's in fullscreen.
⚠️WARNING: May randomly crash when loading a mode sometimes.⚠️
it's me BuggaDude and if you think I'm a fake, I actually updated my profile
seenwonderalex i discovered a glitch
in grand opening when i'm in the detention room baldi sees me through the windows
i would say he'll ban you because he won't fix and he stopped updating, but you said it's only grand opening? and he still works on the grand opening-- wait... how can no update for the game and can update grand opening even without reinstalling?! well, because the game's programmed to download updates for grand opening automatically upon entering-- oh I'm going off track, aren't I?
Nvm i didn't read the full text
I can't decide if this or Attack of the Baldloon is my favorite mod...
This: GIMME MOAR ALL THE FEETCHYOURS¹ (so much stuff like multiplayer and Grand opening and hide & seek and ACHIEVEMENTS)
Attack of the Baldloon: VISUALS TÃO LEGAL²
1 why am I misspelling and screaming
2 still screaming also "tão legal" is "so cool" in Portuguese (Brazil)
Wait why is the elevator not taking me to the ending (I answered 42 mode on to all right)
The 2nd/3rd exit Noise Is The Scariest sound i Ever Heard In my Life, i will truly have Nightmares
i really like this mod, definitely 10/10

Hi seen wonder Alex and everyone
My birthday is on july 15th since my stomach is hurting I wish for everyone to live an amazing and try every day to fight something that comes to them
JUST TO LET YOU GUYS KNOW,
I only comment on this page and the BFNS page. I do not comment on any other page. Check the profile to confirm it's me with my game and the username.
PUNCTUATION ERROR DETECTED:
should be
EDIT: And he already fixed it.
SWA YOU NEED TO SEE THIS!!
What happened
he is copying the name
There‘s someone, who is copying you
who
I forgot it…
Oh wait, nvm, I know who
i login in into wonderseenalex account isnt that
crazy
when you save a game file in a elevator you would name the save file and when you come back to the mode you just playing a ago and theres no continue
It's not a bug. You just got caught null.
Oh ok
Map still showing even though caught by--
This mod will be legend
Hi.
HI?
Hi
Martin where have u been?
Hi
Wha... Who are you copying my profile
Plague doctor old
hello!!
Found a bug when arts and crafters is gone he can come back when the real lockdown ends
It's not a bug it's a feature
jeez it's been months since I posted this comment
Wonder what happened to Martin. He's disappeared for months now.
Yeah, i miss him
Hey, can you try my new games on my page and tell me what your experience was with them?
Uhh he's still on itch.io but he's rude to a lot of people
Who?
Martin
PROTOTYPE is me btw
Nah you're ohiins
Not going lie this is my favorite mod
The grand opening ending with all the answers wrong is actually the easiest because the map is small. Plus if Matt sells apples it will be even easier.
By the way, if I'm not mistaken, the secret formula icon used to be like fire, but the colors were green and red.
did you put sixsixsix into the you can think pad>
I don't think you're supposed to do that, so look out in-
nooooo
Bro did u lock Baldi in the 1x1 room with the Swinging Door and the "Janitors must wear boots when sweeping!" poster with the Swinging Door Sale?!
BRO
sike
Is this harder than BB deluxe? Just asking
What is BB deluxe?
Baldi's basics deluxe
Also here's the page https://gamebanana.com/mods/52963
Oh, I think it's easy if you beat the original game before.
Also fun fact, I was inspired by that creator to make this mod.
Uhm.. I have died like 80 times in BB Deluxe, in my opinion this game you made is easier.
What I mean is, here's the difference: in BB Deluxe, Baldi's slap speed is normal, but the speed when he smacks his ruler I believe is cranked by 3, so when he smacks, he gets 3 times closer to the player, making it hard.
In BBTUD (the ultra decompile), baldi has normal slap speed.
Hello i found a bug when i was playing endless mode i made Baldi stuck in the 1x1 Swinging Door Room i locked it and when i collect 40 notebooks and go to the elevator when i reached floor 2 i saw baldi in floor 1 waiting the elevator to come when i checked the place where i made Baldi stuck in i saw the lock was still there.
It's an optimization thing that I forgot.
Good mod i ever seen, this mod had so many memories for me like when 2.3 to 3.0, until 3.0.4
If this mod still get any updates this mod Will be “the best mod ever”
welp this is not gonna be updated anymore (or idk)
it is
You can decompile using the source code of it
ok
HOW TO SURVIVE A REAL LOCKDOWN!
step 1: before The doors close, quickly make your way to The Principals OFFICE! not the detention room.
Step 2: the first thing you should go to once you enter his office is Go to the left Corner and sit there to wait it out. sometimes the guy will come in but don't move or freak out. he will not see you.
Step 3: survive for 4-6 minutes.
I went to the 2nd floor
He can Spawn On the second floor
why he can spawn
can you make a yt video of guy go to second floor in action
He can't also elevator will be unavailable once lockdown starts
oh
Nah he not. I even made some noise upstairs and he didn't come up.
Or go to floor 2 and wait in math machine room, when the event starts, use the teleporter and wait to event end
How about blue locker
UPDATE BBTUD WE HAD NO UPDATES IN YEARS!!!
LET'S COMMENT BEFORE READING THE DESCRIPTION
Okay, I added a V0.11 item to the game. It's the Invisibility Elixir, but I named it as "Secret Formula." It also has a different icon. I hope y'all enjoy.
my birthday in in 4 days (july 5) :D
Happy early birthday
thanks!!!
WAIT THAT'S MY BIRTHDAY TOO WHAT
happy good earty birthday
happy birthday
i approve
Happy birthday hope I'm not late
Secret formula was added before 0.11. It seems like you are revealing the future
4 years early.
SWA, What is the probability that the shcool event is the real lockdown?
2%
What about grand opening? (When not angering baldi or collecting two notebooks)
I got real lockdown 3 times in one run
WITHOUT CHEATS?
without cheats
I was playing endless
It's been one year and a day since the the V3.0 update... Happy 6 years for bbtud

Indian baldi gamer xx
I never said that in the first image.
Also, I ignored that last post since you asked of some personal info I just don't like giving out here.
And some questions, you can check it yourself instead of asking me.
OK i understood but sometimes i wonder why is there a source code if someone doesn't use it to mod the game
today's QNA for seen wonder alex
1. what's your real name?
2.if you released the game on 2019, then when did you start working on it first time?
3.how many subscribers do you have in your yt channel?
If SWA cannot update the game, we can mod it!
