A re-implementation of Cave Story (Doukutsu Monogatari) engine written in [Rust](https://www.rust-lang.org/), aiming for behavior accuracy and cleaner code.
The engine also contains some (might be buggy and not accurate, everything was pure guess work on data files to avoid legal issues) implementation of Cave Story+ features from both PC and Switch versions.
Note you have to ship the data files yourself if you want to play with those features, but nothing is stopping you from creating a modification of freeware files that uses those new TSC opcodes and features. I'd actually would like to see something cool created using this engine.
The engine should work fine with [CSE2-Enhanced](https://github.com/Clownacy/CSE2) or [NXEngine(-evo)](https://github.com/nxengine/nxengine-evo) modified freeware data files and [Cave Story+](https://www.nicalis.com/games/cavestory+) data files.
- https://github.com/Clownacy/CSE2/archive/enhanced.zip - copy `game_english/data` from archive to the runtime directory (place you run the executable from, usually project root)
- https://github.com/nxengine/nxengine-evo/releases/download/v2.6.4/NXEngine-v2.6.4-Win32.zip - copy `NXEngine-evo-2.6.4-xxx/data` from the archive to runtime directory
**Cave Story+**
- PC release - Copy `data` folder from installation directory ([guide for Steam](https://steamcommunity.com/sharedfiles/filedetails/?id=760447682)) to the runtime directory.
- Switch release - While some support is implemented, hacking consoles and extracting cartridge content is a kind of gray legal area so I will leave it to you...
- [Clownacy/Cucky for CSE2](https://github.com/Clownacy/CSE2) - some game logic reference / mutual help in reverse engineering bitfields and other shit.
- [LunarLambda for organism](https://gitdab.com/LunarLambda/organism) - which is being used by us as `.org` playback engine.
