SoniCPort

Sonic the Hedgehog (1991, Sega Genesis / MegaDrive) C Port

Dependencies

• SDL2 (if COMPILE_SDL2 is set to ON)
• pkg-config (for builds that require static-linkage)

Building

This project uses CMake, allowing it to be built with a range of compilers.

Switch to the terminal and cd into this folder.

After that, generate the files for your build system with:

cmake -B build -DCMAKE_BUILD_TYPE=Release

MSYS2 users should append -G"MSYS Makefiles" -DPKG_CONFIG_STATIC_LIBS=ON to this command, also.

You can also add the following flags:

Name	Function
-DBACKEND=SDL2	Use the SDL2 backend (default)
-DREV01=ON	Compile a REV01 ROM
-DJAPANESE=ON	Compile a Japanese ROM
-DFIX_BUGS=ON	Fix bugs that are blatant screw-ups that may harm performance (not gameplay bugs)
-DLTO=ON	Enable link-time optimisation
-DPKG_CONFIG_STATIC_LIBS=ON	On platforms with pkg-config, static-link the dependencies (good for Windows builds, so you don't need to bundle DLL files)
-DMSVC_LINK_STATIC_RUNTIME=ON	Link the static MSVC runtime library, to reduce the number of required DLL files (Visual Studio only)

You can pass your own compiler flags with -DCMAKE_C_FLAGS and -DCMAKE_CXX_FLAGS.

You can then compile the executable with this command:

cmake --build build --config Release
