If your desire to extract bitcoin has been hampered by a lack of GPU shares and flimsy BIOS locks, YouTuber StackSmashing might help. They have made a Game Boy miner, who only needs a Game Boy console (and a slightly modified Link cable), a Raspberry Pi Pico and a regular computer (via Tom’s Hardware).
The content of the project is that all mining takes place in a warehouse Game Boy, which was released a full 20 years before bitcoin was invented. Of course, it needs some help: Game Boy can not actually connect to the Internet, and it can not hold the entire blockchain. To deal with it, StackSmashing uses the Pico and Link cable to connect to the computer, which runs a bitcoin node. Once connected, the Game Boy hashing program runs from a programmable cassette, and even plays a fun animation while breaking.
Given that Game Boy is a little slower than today’s dedicated mining machines (it apparently runs at 0.8 hashes per second, while some of the fastest ASIC miners run 125 trillion times faster, at 100 terahash per second), it is astronomically unlikely that StackSmashing will actually be able to break any bitcoins. However, when they set up a new bitcoin blockchain with no records on it, they were able to confirm that yes, Game Boy managed to successfully break blocks. Who is ready for GameCoin?
