Reverse Engineering the GameBoy Tetris

This is my first attempt at rever engineering something "big".

The tools and documentations that I used are listed below:

Tools:

• My own emulator: with some custom hacks
• Radare2

Documentation:

• Harddrop page on the GMB Tetris
• MrWint docs on his TAS

Structure

There data folder contains a dump from my own emulator with the code that was executed during a test.

Each line corresponds to one byte at the address space of the gameboy. Empty lines mean:

• That there is code that wasnt executed
• That there is data there
• Or that in the line before there was an instruction that was more than 1 byte long

All the code related comments is stored as a comment in the respective line. For functions I added a small header with some info.

This file has some information on some memory locations. This file has a list of the functions.
