A re-implementation of Cave Story (Doukutsu Monogatari) engine written in [Rust](https://www.rust-lang.org/).

**The project is still incomplete and not fully playable yet.**

#### Data files
|
|
|
|
This repository does not contain any copyrighted files.
|
|
|
|
For better user experience, pre-built binaries are distributed with slightly modified freeware game files.
|
|
|
|
*doukutsu-rs* should work fine with [CSE2-Enhanced](https://github.com/Clownacy/CSE2) or [NXEngine(-evo)](https://github.com/nxengine/nxengine-evo) freeware data files and [Cave Story+](https://www.nicalis.com/games/cavestory+) data files.
|
|
|
|
Vanilla Cave Story does not work yet because some important data files have been embedded inside the executable. and we don't have a loader/extractor implemented yet.
|
|
|
|
##### Where to get them?
|
|
|
|
**Freeware**
|
|
|
|
- https://github.com/doukutsu-rs/game-data - Freeware game data distributed with CI builds, based on those two below.
|
|
- 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 - (Tested only with Steam version, both Windows and Linux builds) Copy `data` folder from installation directory ([guide for Steam](https://steamcommunity.com/sharedfiles/filedetails/?id=760447682)) to the runtime directory.
|
|
- Switch release - **Not supported or actively tested.** Some of release-specific opcodes have been implemented (no code
|
|
decompilation was involved, just pure data file analysis), so you should be able to play it without any major issues.
|
|
Because methods used to extract game data from cartridge vary, you have to find that out on your own.
|

#### Legal note
|
|
|
|
This project includes reverse engineered implementations of NPC and game physics algorithms, derived from freeware Cave Story and PC Cave Story+ executables.
|
|
|
|
Since the game's (non-existent, even for CS+) EULA does not prohibit reverse engineering,
|
|
[according to Secion 103(f)](https://www.law.cornell.edu/uscode/text/17/1201) we could legally revese engineer those parts
|
|
to achieve interoperability.
