What was done
OpenTonic is an ongoing effort to reimplement the Tonic Trouble game engine. Developed with assistance from Claude Code, the project utilizes decompiled outputs and insights from previous Rayman 2 reverse engineering efforts to achieve playable, albeit alpha-stage, gameplay.
OpenTonic is an open-source engine reimplementation for the game Tonic Trouble. The project, documented at https://raw.githubusercontent.com/seco560/opentonic/HEAD/README.md, aims to recreate the original game engine, referred to as Tonic Core. The author reports that the development was assisted by Claude Code, building upon decompiled game outputs and methodologies derived from the Open Rayman project. The current implementation is in an alpha state, functioning as a proof of concept that allows for simulated playthroughs of specific levels, such as the Ski Slope (totalski), and includes basic mechanics like sliding, jumping, and portal transitions. The project maintains a modular structure, featuring an SDL3 frontend for Linux support and a Swift-based package that utilizes Metal APIs for native rendering. The author notes that the project remains a work in progress, with significant tasks remaining, including further decompilation and the implementation of additional game mechanics. Documentation within the project is described as haphazard and largely generated by Claude.
