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.
CAN YOU ADD-
NO. The answer will always be no. There will not be any 0.7 Plus stuff or anything else you suggest. Stop asking!
Want to see old versions?
See old versions from here, all the way up to V3.0.1 (no crashing): UPDATED!

Mr. SeenWonderalex, how do I access your game code?

Buddy, porting characters and items does not mean it's Baldi's Basics Plus.
Oh Yeah, Sorry
Help! I accidentally set the screen resolution to 300*200 without full screen and now I can't change anything in the settings! What should I do?
My game is baldis basics classic remastered
I wanted to comment on official page, but comments on that page was closed
Hey, one question: Can I delete the cache file from the user/appdata/locallow/SWA/BBTUD? IDK what happends, and I got kind of curious, but I didn't want to lose my progress.
The cache file is the updated Grand Opening schoolhouse data that gets downloaded. You can delete it (you have to delete the CRC and the v30_textures though), but when you enter the Grand Opening schoolhouse, it'll redownload themselves.
Hi swa
Ok
Hey Mr. SeenWonderAlex, I want the next update to add Spanish because I'm Latin American.
Sorry, read the description

Hi SeenWonderAlex I Downloaaded Baldi Basics The Ultra Decompile
hey swa how old were you when you started making this mod its fine if you dont wanna answer
i cant log in and i have error 403 how i fix it???

You can't. You're IP banned from the server provider.
i acidently changed my video settings to 1(1x1) help ;-;
I'll tell you: next time, don't close the game when you do that. It would had reverted itself in a couple of seconds.
In the meantime, Alt+Enter will put the game in fullscreen and fix it. If not, complicated process below
hi
Golden baldi and matt. They are not on the wiki
because the wiki was subject to change, leaving some needed pages yet uncreated
and golden baldi will instead be left on the cut content page
so much about this mod changed since 2021
Go to Discord instead of posting in comments.
The fact that the posts are blowing up your notifications.
Ah yes. Good luck trying to buy that until it's too late!
Caption.ini Android
What is this video that is PRIVATE?
It's public now
What is this song I never heard this song in the game?
Is this a secret?
5% chance
what 5% chance????
BRO, I HAD THAT EVERYTIME I GO TO MULTIPLAYER, WTF? :Skull:
Supposed to be 5%. Your device has some specific behavior of its random number generator.
1 player online :(
Hope y'all in US (East).

I think that's a little TOO brutal..
true but still
In the old version of bbtud there was a golden baldi. But there's no on wiki. But is the myth true? I saw it in the Mod menu. When I'm enabled the golden baldi. I cant found him everywhere
It is actually possible to activate Golden Baldi in V3.0.
How?
Loading a very old save from the game (V1.4 and below)
I wonder what the golden baldi looks like
https://www.mediafire.com/file/6i917u96z5ic64z/legendary_schoolData.dat/file
actually you could add him in the wiki
Yes, I know, but if i don't know how it works or what the action looks.
hi
Hi
I never expected the comments section was still alive, other than the game.
i guess everyone loves to comment now that the game's dead
how the hell do i remove null
only way to remove null is to erase ur entire data or just beat null mode to get all of the game modes back
or attempt 5 times
Lol
Bruh. What's so funny, eh?
Play pvz fusion
??
plants vs zombie fusion edition
Idk. I never played that game before.
lol
Ayyy, ross!

It's for an secret and epic labeled achievement.
You get some hundreds of coins for it.

I'm actually not lying. You get an achievement with coins.
Why'd you change your name bruh, I still recognize you!

You can edit the file called "captions.ini"

It's on the data folder.
Is it this?
