FNF games are built on Haxe/OpenFL and can be partially reverse-engineered using tools like JPEXS Flash Decompiler (for SWF files) or specialized GameMaker decompilers for FNF: GMS2 Remake projects. However, mod creators often use Lua scripting to keep their custom content separate from the core engine, which actually makes it easier to extract and study.
The (also known as Vs. Sonic.exe V3) source code refers to the unreleased and eventually cancelled version of the popular Friday Night Funkin' (FNF) mod. Official Status and Availability
Older GameMaker versions (7 and below) had decompilers that could extract .gmk files from .exe executables by simply dragging the EXE onto the decompiler tool. However, newer versions (GameMaker Studio 2 and later) use more robust compilation methods, making decompilation significantly harder. UPX-packing (a common executable compression technique) can also prevent decompilers from functioning properly. sonic.exe 3.0 source code
. While originally a creepypasta, this mod brought the horror character into the gaming mainstream, and the narrative surrounding its 3.0 release is a complex story of community development, cancellation, and eventual restoration. 1. The Context of Version 3.0

Originally intended to be the definitive expansion for the popular horror-themed mod, the 3.0 update (sometimes referred to as the 2.5 build in its unfinished state) was cancelled due to internal drama, leaks, and the developers' desire to prioritize their mental health. Despite the cancellation, an unfinished build—including its source code—was eventually released to the public so fans could experience the scrapped content. Technical Overview: What's Inside the Code?
As the community grew, so did the demand for a more polished experience. This culminated in the development of Sonic.exe Version 3.0 (often associated with major overhauls, community recodes, or definitive fan continuations like Sonic.exe: The Disaster or the Sonic.exe One Last Round lineages). Version 3.0 aimed to fix the technical limitations of the original GameMaker builds. It introduced: Despite the cancellation
Once a horror event is triggered, the source code immediately overrides player inputs ( keyboard_clear or ignoring controller states) to lock the player in place.
