A simple Cheat Engine clone for Linux.

phax

A command-line "Cheat Engine" clone for Linux, implemented using ptrace.

Usage

Run the "hackme" program:

gcc hackme.c -o hackme
./hackme

Run the phax wrapper script:

./run.sh `pidof hackme` i32

How does it work?

It attaches to the target process using the ptrace API, parses /proc/<pid>/maps to determine valid memory regions, then scans through those regions by reading /proc/<pid>/mem. Modifying values is done by writing to the same file.

Why doesn't it work on floating point numbers?

Short answer: because I'm lazy.

Long answer: because floating point numbers have a lot of precision, and unless you know the exact value, you typically need a range of values rather than a single value. Searching for a range with acceptable performance is much more complex than searching for a single value, so it is not implemented at this time.
