|

|
|
A re-implementation of Cave Story (Doukutsu Monogatari) engine written in [Rust](https://www.rust-lang.org/), aiming for behavior accuracy and cleaner code.
|
|
Later plans might involve turning it into a fully-featured modding tool with live debugging and stuff.
|
|
|
|
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 project is still incomplete and might not be playable. Expect lots of breaking changes and bugs**

#### Data files
|
|
|
|
This repo does not redistribute any copyrighted files.
|
|
|
|
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.
|
|
|
|
Vanilla Cave Story does not work yet because some important data files are embedded inside executable and we don't have an extractor 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 - 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...
