🎮 Game Description
Reality is a pointer… and you just dereferenced NULL.
Welcome to The M0+rix: Segfaulted, a handheld first-person shooter where the only way out is through the system’s deepest vulnerabilities. Running on the MSPM0 microcontroller, this game turns embedded systems into battlegrounds, with PVP combat over UART and a retro-style 3D world.
Dodge enemy fire, navigate the simulation, and exploit every loophole in the code—because in this world, even one bad instruction could bring everything crashing down. Are you the debugger or just another broken process?
🔥 Features:
- ✅ First-person shooter with a Matrix-inspired digital battlefield
- ✅ Real-time PVP over UART – battle your opponent in low-level style
- ✅ Optimized for MSPM0 – embedded gaming meets high-speed action
- ✅ Handheld experience – take the simulation anywhere
- ✅ Segfault or escape? – The system is unstable, and only one player will survive
💾 Flash in. Boot up. Overwrite reality.

Questions
How big is the M0+rixPCB PCB?
It measures 140.8 × 66.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the M0+rixPCB use?
50 parts, built around the TSOP31438 and ULN2003BD. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the M0+rixPCB KiCad files?
From the SuryaUT/TheM0trix_Segfaulted repository on GitHub, at the commit this page was made from: the board is M0+rixPCBFiles/M0+rixPCB.kicad_pcb and its schematic M0+rixPCBFiles/M0+rixSchematic.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the M0+rixPCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask SuryaUT before reusing the design.
