Reverse engineering GBA gamesFrom zero to your first patch: take Pokemon FireRed, understand how it works internally, and change game behavior with your own code.

  1. 00 Start here Workshop overview, prerequisites, and lesson order.
  2. 01 The GBA architecture The hardware, ARM7TDMI CPU, and console memory map.
  3. 02 Reading ARM and Thumb Registers, instructions, and how to read the CPU's machine code.
  4. 03 Tools and setup mGBA, Ghidra, Python, Capstone, and GDB ready for class.
  5. 04 Static analysis in Ghidra Follow the boot path from the only known address and infer the structure until you find the main loop.
  6. 05 Dynamic analysis: finding HP Find HP in RAM with mGBA and GDB, and find the instruction that applies damage.
  7. 06 Finding and cleaning up the function Close the HP function in Ghidra and make the decompile readable: real before and after.
  8. 07 The first patch Write, assemble, and install a hook that makes the enemy faint in one hit.
