(SPOILERS) How do i play NULL Mode again?

[Goldy333]

I like NULL Mode, but after you beat it, it gets replaced with Glitch Style. How do i modify my save file in order to play NULL Mode again?

From my comment on another post

I dug a little bit and there is a value in a save file, that corresponds to nulls removal (flags[4] to be exact), however, changing it would not help, because it's changes back if you have NULL achievement.
It you want to bring him back, you need to "unachieve" NULL achievement (by using steam achievement manager) and remove save data, or change flag[4] to false.

P.S. You need to manually remove save file in %UserProfile%\AppData\LocalLow\Basically Games\Baldi's Basics Classic Remastered, doing it ingame will not reset the fifth flag

What is the save file that has flags[4]/flag[4]?

UnassignedSave

[Goldy333]

is the file in C:\Users\R2\AppData\LocalLow\Basically Games\Baldi's Basics Classic Remastered? because the files there are just HighScores.hgh, Player, PlayerConfig_!UnassignedFile, PlayerFile_!UnassignedFile, Player-prev and steam_autocloud.vdf. Which one is it?

[|i.c.c.n|]

the save file should be PlayerFile_!UnassignedFile.sav (the extension of which your computer is likely hiding from you by default)

that's just how the file looks if you load it in a text document, you need to find a save editor to view the file more properly

unfortunately however I don't know that part, if Treeshold could elaborate though that'd be really helpful (or if I got the file wrong then please clarify)

Save files are encoded using AES. The cipher is the name of the save file (!UnassignedFile). I am trying to figure out how to decrypt and encrypt the save file, but no luck yet.

Aren't the Save Files encoded with CBC AES? If so then the game's key should be somewhere.

I have created save file encryptor/decryptor, give me a second to upload it to github!

[Treeshold]

You can find the decryptor/encryptor here[github.com]. If you don't know the save file folder, it's in %UserProfile%\AppData\LocalLow\Basically Games\Baldi's Basics Classic Remastered

[Treeshold]

decryptedSave.txt should contain something like this
{"saveVersion":0,"achievementData":{"found":[true,true,true,true,true,true,true,true,false,false,false,true,false,false,true,true]},"gamesSinceError":5,"errorCount":0,"classicWon":false,"partyWon":false,"demoWon":false,"glitchWon":false,"bossSeen":false,"flags":[true,true,true,true,true,false],"reduceFlashing":false}.

If you want to bring null back, you have to change the fifth value, like this:
{"saveVersion":0,"achievementData":{"found":[true,true,true,true,true,true,true,true,false,false,false,true,false,false,true,true]},"gamesSinceError":5,"errorCount":0,"classicWon":false,"partyWon":false,"demoWon":false,"glitchWon":false,"bossSeen":false,"flags":[true,true,true,true,false,false],"reduceFlashing":false}.

[Treeshold]

After that, just encrypt the save file back and you are good to go
remember to unachieve NULL achievement

[Goldy333]

ooo ok lemme try

[Goldy333]

It didn't work, i think it's because i just get NULL achievement back when i open the game
