Few weeks ago, I developed TamaLIB, a hardware/OS agnostic Tamagotchi P1 emulator library, that allowed me to create a Tamagotchi P1 ROM exploration tool called TamaTool that targets desktop computers, and a MCU oriented Tamagotchi P1 emulator called MCUGotchi (see my previous post for more information).
Now, let me introduce PebbleGotchi, a Tamagotchi P1 emulator for the Pebble smartwatches !

Few weeks ago, I found my old Tamagotchi P1 in some old stuff I had, and I wondered if somehow someone hacked it. After some research, I found out that the ROM has been successfully extracted from the picture of a die, and that it could be run on some MAME emulator. But I really wanted to play around with the ROM, and wondered if it would be possible to run it on an embedded system, like a Smartwatch or an STM32 MCU based board.
So to satisfy my curiosity I decided to develop my own Tamagotchi P1 emulator !

Few months ago, I got a Weloop Tommy smart-watch from work. I played with it a little bit, but quickly put it aside, until someone recently reminded me about this open source firmware called OSSW (the corresponding Hackaday.io project page can be found here). I thought it would be a great sandbox to start playing with the watch, but building the FW was only possible using Keil and Windows...
For this reason, I set up a fork on my Github account that has been adapted to build on Linux (or Cygwin) using GCC. It can be found here.

I played a little with the discontinued Rovio from WowWee this week, and found out that the firmware source code has been released some times ago.
Several custom firmwares already exist, but I played with only one so far : Rovio Chat custom firmware. This custom firmware integrates some interesting functionalities (mainly a Network Watchdog), but I wanted to add other features, like turning ON/OFF the blue LEDs.
That's why I just set up a Github repository, importing the original source code (v5.03) with Rovio Chat changes on top of it as a starting point.
So far, I also added the following functionalities :
The repository can be found here, and some nice building instructions here.
Feel free to check it out !
