You cannot run games on a modified device
The Game Boy, released in 1989, was one of the first mobile gaming devices that became popular worldwide and beloved by gamers in the 1990s.
Today the Game Boy is already a rarity. Zaku Mods Studio turned the Game Boy into a digital car dashboard that shows your driving speed.
The published video quickly gained popularity on social networks. It was originally planned that this would be a one-off project, but after a wave of positive reviews, Zaku Mods Studio began accepting pre-orders, inviting interested parties to contact the developers for details.
The modified Game Boy will no longer allow games to run, as the internal parts have been replaced with digital counters and other stuff, leaving only the outer casing. Therefore, the modified Game Boy — it's just a shell, and the real function is — instrument panel.
In the comments there were also skeptics who questioned the practicality of the device due to the inability to play games, as well as redundancy of information (after all, the speed is visible on the analog speedometer).
