-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.

+This repository does not contain 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.
+For better user experience, binaries are being distributed with slightly modified freeware game 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?

 **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... 
+- Switch release - Not supported, because extracting the data files from the console is complicated and requires 
+device-specific decryption keys. Some of release-specific features have been implemented, so you should be able to play 
+it without any major issues. Google will likely help you if you really want to.
