  Real Racing 3 — preservation project

  reverse eng.

  EA's servers shut down in March 2026, so the game doesn't have to. Cracked the save encryption and cloud-sync protocol, applied 21 binary patches to a 33 MB ARM64 library, archived the full 17 GB CDN, and wrote a FastAPI private server. The game boots and races against my infrastructure.

  Canon LBP2900B — Linux driver

  open source

  Canon never shipped a Linux driver, so I reverse-engineered the CAPT protocol from USB captures and fixed the community driver: correct paper-size codes, error and jam recovery, transport reliability, multi-page jobs.
