I reversed the ‘evolve’ function in the Tamagotchi Friends to make the first ‘growth chart’ for this Tamagotchi version. Growth on the Tamagotchi Friends is determined by how [..]
I used voltage glitching to dump the code of the Tamagotchi Friends. Recently, I experimented with the EEPROM of the Tamagotchi Friends. I didn’t manage to get code [..]
I dumped the EEPROM of the Tamagotchi Friends and altered it to see if it could be used achieve code execution on the device. The Tamagotchi Friends’ processing [..]
I used a Proxmark 3 to emulate the Tamagotchi Friends’ NFC. This confirms it is indeed low-frequency RFID, and shed some light on the NFC format.
I tried decoding the Tamagotchi Friends NFC with a Proxmark 3, but had limited success, so I went back to looking at it with an oscilloscope. I was [..]
I recently got a Proxmark 3, and used it to read the NFC of the Tamagotchi Friends. This allowed me to get some data on the protocol.
There’s a new Tamagotchi in town, so of course I had to get one (or two or three) and take it apart. The Tamagotchi Friends is the latest [..]
I found a software debug mode in the Tamagotchi code that allows the game state to be viewed and changed in ways that aren’t normally allowed. This mode [..]
