The project works by using the Arduino Nano as the bridge between a standard PS/2 mouse and the MSX mouse port.</p> <p>The design is based on <a href="https://github.com/denjhang/MSX-Nano-Mouse-2025">denjhang’s MSX Nano Mouse 2025 repository</a>, which provides both the Gerber files for the PCB and the firmware source code. Having those files available made the build straightforward and inexpensive: I could order the board, assemble the small set of components, flash the Nano, and connect a PS/2 mouse.</p>
