Pokewalker Reverse Engineering

This project (and wiki) has been superceded by this article by Dmitry.GR. This repo has been shelved since the goal it was aiming for has been acheived. See below for active related projects. Huge thanks again to Dmitry who cracked it all on his own - and thanks to the contributors to this repo.

This project is about reverse engineering the PokeWalker, a device designed for use with the Pokemon HeartGold and SoulSilver games.
