The normal compression function adds extra information that is not necessary in the imagebank. Seventh in zlibdata.py: a new LZX compression function for the imagebank was added. Sixth in mfa.py: some chunks that would not load previously now are loaded using a different method. The second short is just ignored, as it doesn't contain anything useful. This reduces the size of the resulting MFA by quite a bit!įifth in objects.pyx: the object's flags are read as a single short, instead of as an int (an int is two shorts). Third in events.pyx: the new ERop header tag is correctly parsed, and the missing events in some games has been fixed.įourth in imagebank.pyx: the decompiler will compress the textures in the MFA before writing them to the MFA using LZX compression. Second in names.py: the wording for alterable values has been changed. The decompiler will check the build version of the game and use the right method to decrypt the chunks. In build 285 and newer, the encryption key is calculated in a different order.
Clickteam fusion 2.5 decompiler cracked#
I'll write a description of the changes here for the technically curious, or you can go on my GitHub repo to download the files and compare what's changed.įirst in chunk.pyx: the new encryption in Mode 4 is cracked properly, it uses a simple XOR function and a bitshift. I assure everyone the same fate will not happen with this tool.Īnyways now on to the part everyone has been waiting for: there are only 9 files that are different between anaconda-mode3 from late 2015 and this decompiler update.
Clickteam fusion 2.5 decompiler series#
I know it's been years since the decompiler has been updated, I had only recently got back into this series after Clickteam killed off CTFAK.
Mode 4 encryption is actually very similar to Mode 3 (just an added bitshift and a stupid XOR operation), it's not even its own mode in Clickteam actually, but we all refer to it as Mode 4, so it stuck.īefore I get any further, I'd like to thank everyone who has made this possible: 1987kostya and ClickNinYT (Sad-Fix-7915 on reddit) for their help with Mode 4, Mathias Kærlev for the original Anaconda tool, Blue Nova for an automatic decompiling script, autorek for Mode 3, and Kekmasterfnaf for mode 3 image fixes. This release also fixes broken events and black/bugged textures some people were having with the old "anaconda-mode3" decompiler from 6 years ago which was the last public release I know of. I've also added some quality of life features, like the MFA file being automatically named according to the game's title string, instead of always being called "out.mfa".
This is required for large games like Sister Location, because Fusion 2.5 does not support MFAs larger than 4 GB, as it is a 32-bit program. This decompiler release has 3 new major features: it supports the new chunk encryption ("mode 4"), it supports the new event header structure in the latest releases of Fusion 2.5 (ERop header tag, I call this "mode 4.1"), and also compresses the MFA. 2.5+ support is coming soon, but no official FNaF game uses it yet so I did not include it with this decompiler. This means you can decompile every game in the FNaF franchise (FNaF 1 through 4, Sister Location, UCN, FFPS, Freddy in Space, Fury's Rage, etc), and get the MFA file to explore how the game works. (please read the entire post before you download it from my GitHub repo) Hey guys, I am happy to announce that I've updated the decompiler (Anaconda) to support decompiling ALL Clickteam Fusion 2.5 games.
