Pokemon Red Cable Club Hack

https://www.youtube.com/watch?v=m3e_SyhE3xc

This is a proof of concept to demonstrate a buffer overflow in the Cable Club. This project contains the assembly and binary data that is sent to the Gameboy along with two ways to send it.

Arduino

Cut open a link cable open and wire it to the Arduino like so:

 ___________
|  6  4  2  |
 \_5__3__1_/   (at cable)

Cable Pin   Name           Arduino Pin
   1        VCC                N/A
   2        Serial Out         6
   3        Serial In          3
   4        Serial Data        N/A
   5        Serial Clock       2
   6        GND                GND

Upload the program inside the arduino folder and run Pokemon red. Visit the Cable Club and proceed to the Trade Center where the program will execute.

BGB Emulator Link

Start the emulator with Pokemon Red. Right click on the emulator window and select Link > Listen. Then run the python script, with an optional port to connect to (default is 8765).

./bgb_link.py [port]

Building Your Own Program

• Copy a directory like the hello project in the asm folder
• Edit the build and linkfile to match the name of your project (change "hello" to whatever you are naming your files)
• Then go to the py directory, edit the cable_club.py to open your bin file instead.
• If running on the Arduino, run cable_club.py (python cable_club.py) and copy the new DATA_BLOCK array line (replacing the old one) to the pokemonspoof.h file in the arduino folder. Upload to the Arduino and run.
