A custom DLL-injection module for hooking into a game called Midtown Madness 2.

• Allows for bug fixes and/or custom features to be added into the game
• Mapped out ~95% of the binary using a symbols map from a beta version of Midtown Madness 2
• Learned a good portion about the Angel Game Engine and how it works
• Wrote a custom hook framework that allows for code from the original binary to be easily accessed
• Added support for Lua scripting using LuaIntf to bind functions… Show more

• Added support for Lua scripting using LuaIntf to bind functions from the binary
• Implemented fixes for various bugs, including a "heap overrun" error that frequently occurred
• Worked together with a few friends to polish up existing code and add new features
• Helped implement support for Discord Rich Presence
• New builds uploaded regularly using AppVeyor
• Automatically posts GitHub updates and new builds posted in the community Discord server using bots Show less

A custom storage format that utilizes scopes and a Python/C-like syntax.

Intended as an alternative to other methods of data serialization; one that not only looks beautiful, but is also easy to understand and edit by hand.

A various collection of modding tools for games such as Driv3r, Driver: Parallel Lines, Driver '76 and Driver San Francisco.

[Antilli]
• Based on an idea that started life as a MaxScript in 3ds Max
• Supports importing models and textures that make use of multiple proprietary file formats
• Reverse engineered and reimplemented dozens of proprietary file formats
• Experience reading and writing file formats with multiple versions and platform differences
• Partially… Show more

A command-line based tool for extracting and modifying binary object data for games running on Ubisoft's Dunia™ engine or a subset of it (e.g. Far Cry, Watch_Dogs, The Crew, etc.)

• Works with files that commonly have the .FCB file extension, hence the name (courtesy of Deebz__)
• Converts binary data into XML files that can be edited using a text editor, then recompiled back into binary data
• Wrote a custom framework for parsing plain-text from XML as binary data or another… Show more

• Converts binary data into XML files that can be edited using a text editor, then recompiled back into binary data
• Wrote a custom framework for parsing plain-text from XML as binary data or another well-defined type (e.g. int, float, etc.)
• Required very intricate knowledge of binary data that does not have any kind of alignment or data types
• Uses object name hashes to determine what kind of data is stored
• Reverse engineered and reimplemented the custom compression used to make files smaller (i.e. back-reference offsets)
• Experimental support for extracting custom user maps from Far Cry 5 using LZ4 decompression Show less

A Lua 5.1 decompiler library written in C#. Based on the original Java version of "unluac" by tehtmi.

Not being actively developed at the moment, but may revisit it in the future. Most work was done between 2014 - 2016, on an as-needed basis. It was shortly revisited in November 2018 after a friend showed interest in using it in one of his programs.

It is comparable to the Java version of unluac as it was in November 2014. Support for Lua 5.0 was not implemented, as it was not… Show more

It is comparable to the Java version of unluac as it was in November 2014. Support for Lua 5.0 was not implemented, as it was not something I required.

• Rewrote the entire core functionality of unluac from scratch, without the help of any Java->C# conversion tools
• Fixed a couple of bugs along the way Show less
