Workboy was a 1992 Game Boy add‑on that turned the handheld into a micro workstation. It featured a detachable keyboard and software for appointments, contacts, currency conversion and five‑language translation. Advertisements ran in contemporary gaming magazines, but the product never shipped. A ROM dump surfaced in the September 2020 Nintendo leak, confirming the unfinished build. The device was slated for a Q4 launch before development stalled.

The leaked ROM runs correctly only when paired with the prototype keyboard discovered by Liam Robertson. In December 2020 the DidYouKnowGaming? channel posted video evidence of the keyboard interfacing with the cartridge, showing the full title screen and version strings. Internally the code lists version 5.74, while the displayed title reads 8.87, hinting at a last‑minute build change. suggesting a rushed finalization before the planned release.

Licensing records show Fabtek held exclusive rights to the title, with Nintendo listed as licensor. The project's cancellation left a curious footnote in handheld history: a functional productivity tool that could have expanded the Game Boy’s role beyond gaming. The recovered ROM and keyboard now serve as a rare glimpse into early handheld software experimentation and underscores the challenges of hardware‑software integration at the time.
