# Cave Story Engine 2 Cave Story Engine 2 is a decompilation of Cave Story, ported from DirectX to SDL2.  ## Disclaimer Cave Story Engine 2 is based off of the *original freeware release* by Studio Pixel, and is not based off of Nicalis' ports, and contains no extra features included in said ports (graphics, audio, and other changes). ## Dependencies * SDL2 * FreeType * pkg-config * FLTK ## Building ### CMake This project primarily uses CMake, allowing it to be built with a range of compilers. In this directory, create a directory called 'build', then switch to the command-line (Visual Studio users should open the Developer Command Prompt) and `cd` into it. After that, generate the files for your build system with: ``` cmake .. -DCMAKE_BUILD_TYPE=Release ``` You can also add the following flags: * `-DJAPANESE=On` - Enable the Japanese-language build (instead of the unofficial Aeon Genesis English translation) * `-DFIX_BUGS=On` - Fix bugs in the game (see [src/Bug Fixes.txt](src/Bug%20Fixes.txt)) Then compile CSE2 with this command: ``` cmake --build . --config Release ``` If you're a Visual Studio user, you can open the generated `CSE2.sln` file instead. Once built, the executables can be found in `build_en` or `build_jp`, depending on the selected language. ### Makefile (deprecated) Run 'make' in the base directory, preferably with some of the following settings: * `RELEASE=1` - Compile a release build (optimised, stripped, etc.) * `STATIC=1` - Produce a statically-linked executable (good for Windows builds, so you don't need to bundle DLL files) * `JAPANESE=1` - Enable the Japanese-language build (instead of the unofficial Aeon Genesis English translation) * `FIX_BUGS=1` - Fix bugs in the game (see [src/Bug Fixes.txt](src/Bug%20Fixes.txt)) * `WINDOWS=1` - Enable Windows-only features like a unique file/taskbar icon, and system font loading (needed for the font setting in Config.dat to do anything) * `RASPBERRY_PI=1` - Enable tweaks to improve performance on Raspberry Pis * `NONPORTABLE=1` - Enable bits of code that aren't portable, but are what the original game used ### Visual Studio .NET 2003 Project files for Visual Studio .NET 2003 are available in the 'msvc/msvc2003' directory. Visual Studio .NET 2003 was used by Pixel to create the original `Doukutsu.exe`, so these project files allow us to check the accuracy of the decompilation by comparing the generated assembly code to that of the original executable. This option is **strictly** for checking the decompilation's accuracy; CMake should be preferred in all other situations. ## Running In order to run Cave Story Engine 2, you have to get the "data" folder from a vanilla copy of Cave Story. Just copy and paste it into the same folder as the executable. ## Licensing Being a decompilation, the majority of the code in this project belongs to Daisuke "Pixel" Amaya - not us. We've yet to agree on a license for our own code.
