During March 2025, Kevin Mitton focused on build engineering and platform packaging for the libretro/RetroArch repository, delivering packaging support for the lr-dice emulator core on Apple platforms. He integrated the dice core into RetroArch’s Apple Store packaging workflow, aligning with established standards to ensure compatibility and reproducibility. Using Shell scripting and platform packaging techniques, Kevin prepared new build artifacts and metadata, enabling future App Store submission and expanding RetroArch’s distribution reach. While the work was limited in scope to a single feature, it demonstrated careful attention to workflow integration and artifact readiness, laying groundwork for broader Apple platform support.
