TL;DR
A prototype of the unreleased ‘Workboy’ for GameBoy has been leaked, showing a device that transforms the handheld into a mini workstation with a keyboard. The ROM and prototype keyboard have been recovered and demonstrated publicly for the first time.
A prototype of the unreleased ‘Workboy’ for GameBoy has been recovered, confirming its design and functionality. The device, intended to turn the GameBoy into a micro workstation with a keyboard, was never officially released but has now been demonstrated using leaked ROM and prototype hardware.
The ‘Workboy’ was developed for the GameBoy platform and intended to provide productivity features such as managing appointments, addresses, notes, bank balances, and currency conversions. It also supported multiple languages and temperature readings. Although advertisements appeared in video game magazines at the time, it was never officially launched.
The ROM for the ‘Workboy’ cartridge was leaked in September 2020 among a batch of Nintendo-related materials. A prototype keyboard, thought lost, was later shown in a YouTube video by Liam Robertson, demonstrating that the leaked ROM works with the hardware. The device displays a version number of 8.87, though code strings indicate a previous version of 5.74.
Implications for Retro Hardware Preservation
The discovery of the ‘Workboy’ prototype and ROM provides insight into Nintendo’s experimental peripheral projects during the early 1990s. It highlights efforts to expand the GameBoy’s functionality beyond gaming, showing a unique intersection of handheld gaming and portable productivity devices. This find offers valuable material for collectors, historians, and enthusiasts interested in Nintendo’s hardware innovation and unreleased projects.
