What was done
This project provides a native SEGA Dreamcast port of the 2013 Sonic the Hedgehog mobile remaster, built using the RSDKv4 decompilation. The port requires user-provided game data and supports VMU saves, though networking features are disabled.
The DCRSDK/Sonic1-DC project is a native port of the 2013 mobile remaster of Sonic the Hedgehog for the SEGA Dreamcast. It relies on the RSDKv4 decompilation as a foundation. The author reports that the project was created almost entirely using Claude AI. Users must provide their own Data.rsdk file from the 2013 mobile version, as the port does not include game assets. The build process requires KallistiOS, mkdcdisc, and ffmpeg for asset generation. Music and sound effects are converted to raw PCM, as the Dreamcast build lacks a Vorbis decoder. The port supports VMU saves, custom icons, and the game's original menus and special stages. Networking features are disabled, and leaderboard uploads are non-functional. A known limitation involves the end credits music, which desynchronizes from the frame-timed sequence. A developer menu is available but requires manual configuration in settings.ini. The project documentation is available at https://raw.githubusercontent.com/dcrsdk/sonic1-dc/HEAD/README.md.
Reproduce it
Clone the repository and follow the instructions in BUILD_DREAMCAST.md, ensuring an existing KallistiOS and mkdcdisc installation. Provide the Data.rsdk file from the 2013 mobile remaster and run the asset generation script.
