About the license

Chiku released the source code of Syobon Action to allow others modifying it, however he didnt use a license... Instead he included a japanese readme.txt with the following text:

スパゲティソース かつ タブが一度も使用されてないうえ、
クラスわけ無しにif文大量使用のカオスを解読できる方はどーぞｗ
ご自由に改造なさって下さい。

ただ、そのままのソースを配布するのはご遠慮下さい。

In english it somewhat translates to:

Spaghetti sauce. The tabs aren't used even once, and the code is a chaotic mess of tons of if statements without any class divisions. If you can decipher it, go ahead!
Feel free to modify it as you like.

However, please refrain from distributing the source code as is.

So, as you can see, Syobon Action mods based on the original code can NOT use a open source license, due to the amount of developers that modified it and the unclear license situation.

Building

Note

For Windows users:

You need the MinGW-w64 toolchain to build this, you can install it by using MSYS2

Also make sure you are using MinGW cmake and make and NOT other one, otherwise you will get building errors, also when doing the cmake step add -G "MinGW Makefiles" -DCMAKE_C_COMPILER=gcc -DCMAKE_CXX_COMPILER=g++ to make sure it will be built using MinGW

It could work by using another toolchain but MinGW-w64 is the only one tested

This project requires the following SDL3 libraries, they are included in this repository as submodules and they will be compiled when building SyobonKZ:

• CMake
• SDL3
• SDL3_image
• SDL3_mixer
• SDL3_ttf
• SDL3_gfx

Alternatively you can build SyobonKZ using SDL 1.2 (for old platforms), but note that SDL 1.2 itself is NOT included in this repository:

• CMake
• SDL 1.2 (or sdl12-compat with SDL2)
• SDL_image 1.2
• SDL_mixer 1.2
• SDL_ttf 1.2
• SDL_gfx (dont confuse with SDL2_gfx)

As mentioned, the SDL 1.2 extensions and all SDL3 libraries are included as submodules in this repository, to build this project you need to include them when cloning by doing:

git clone --recursive https://github.com/M0REKZ/SyobonKZ.git

After that you can do the following to build the game:

mkdir build
cd build
cmake ..
make

If you want to use SDL 1.2 instead, use this CMake option:

cmake -DSYOBONKZ_USE_SDL3=OFF ..

Gamepad Notes

Your gamepad or joystick may not work by default with Open Syobon Action. Check joyconfig.h for more information.

TODO:

• Font thickness (Not really important)
• Port to other operating systems (iOS, etc.) #3
