If your desire to mine bitcoin is thwarted by a lack of GPU stock and weak BIOS locks, YouTuber StackSmashing maybe can help. They’ve created a Game Boy miner, which only needs a Game Boy console (and a slightly modified Link cable), a Raspberry Pi Pico, and a regular computer (through Tom’s Hardware
The conceit of the project is that all mining is done on a stock Game Boy, which was released 20 years before bitcoin was invented. It does need some help, of course: the Game Boy cannot really connect to the internet and cannot hold the entire blockchain. To deal with that, StackSmashing uses the Pico and Link cable to connect to the computer running a bitcoin node. Once plugged in, the Game Boy will run the hashing program from a programmable cartridge and even play a fun animation while mining.
Considering that the Game Boy is a little slower than current mining machines (apparently it runs at 0.8 hashes per second, while some of the fastest ASIC miners are running 125 trillion times faster, with 100 terahashes per second), it is astronomically unlikely that StackSmashing could actually mine bitcoins. However, when they set up a new bitcoin blockchain with no records on it, they were able to confirm that yes, the Game Boy was able to mine blocks successfully. Who’s ready for GameCoin?
