What was done
Little Planet is a Sonic CD port built from a byte-identical disassembly and static recompiler. It features True16:9 widescreen, a remastered opening, and high-level HLE implementation of Mega-CD hardware, requiring a user-provided disc image.
Little Planet is a Sonic CD recompilation project that provides a disassembly of the game's code, which reassembles byte-identical to the original disc. A static recompiler translates this code into C, which is then executed and verified frame-by-frame against an interpreter. The project implements the Mega-CD hardware, including the 68000 CPUs, Z80, VDP, and audio chips, using a high-level implementation (HLE) to replace the original BIOS. The README documents that the Japanese release (G-6021, SHA-1 5b0ac16233028bcd8691c71b0a749b8d485dae7c) is the primary tested version, while others may boot but remain untested. Development commits in the project repository include the strings 'Co-Authored-By: Claude Opus 5.5 [email protected]' and 'Co-Authored-By: Claude Sonnet 5.5 [email protected]' in their metadata. The port supports True16:9 widescreen, a 4K 60 fps remastered opening, and various CRT filters. Users must provide their own disc image, as no game data is included. The project is available at https://raw.githubusercontent.com/carlosrmz009/littleplanet/HEAD/README.md.
Reproduce it
Build the project using the provided scripts (build_linux.sh, build_mac.sh, or build.bat) and run the resulting binary with a path to a valid Sonic CD disc image (e.g., ./build/littleplanet path/to/sonic.cue).
