Bit Slicer is an open-source universal game trainer for OS X, written using Cocoa and Mach kernel APIs.
It allows you to cheat in video games by searching and modifying values such as your score, lives, ammunition, and much more.

- Memory Scanner
- Search & narrow down values of several types: integers, floating-points, strings, byte arrays, and pointers
- Add, delete, and modify variables with ease
- Freeze variable's values
- Store a process' entire virtual memory space and search for values based on incremental changes
- Manipulate pointers by dereferencing variable addresses
- Memory Viewer
- View memory live in a hex editor style window
- Dump memory to files on disk for manual inspection
- Modify memory protection attributes
- Debugger
- View live disassembly of instructions
- Modify instruction's bytes directly, or by assembling instructions (including nopping)
- Set breakpoints, resume from them when they're hit, view backtraces, manipulate thread registers, and step into/out/over instructions
- Watch for what instructions access a variable in a document
- Save slice documents so that you can send cheats to your friends
- Pause and un-pause current process
- Undo & Redo many kinds of changes, including searches
- Evaluate mathematical expressions automatically (eg: in a flash game, search for 58 * 8)
- Run as a normal user, not as the superuser (root)!
- Enjoy OS level features such as auto-saving, document versioning, window restoration, notification center, etc.

Bit Slicer is licensed under the 3-clause BSD license. Versions prior to 1.6, however, are licensed under the GPL version 3 license.
In order to build Bit Slicer, code signing is required to gain sufficient privilleges to using task_for_pid(). Building with the Debug scheme uses a self-signed certificate (which only works locally) and building with the Release scheme uses my purchased Developer ID certificate (which works for distribution).
In order to build Bit Slicer in Debug mode using a self-signed certificate, please follow these instructions. Note that this involves more steps than code-signing typical applications.
Versions prior to 1.6 are not code-signed, and consequently, the user is required to authorize the application to run as the superuser.
