clownmdsdk is a toolchain for developing Sega Mega Drive/Sega Genesis homebrew in freestanding C++. The toolchain includes GNU Binutils, GCC, and some essential libraries and scripts.
Unlike SGDK, this is explicitly NOT a framework nor game engine: this project's sole concern is enabling the creation of bare-metal Mega Drive software using C++; handling controller inputs, playing sounds, and displaying graphics are all tasks which are left to the user.
Building requires a Unix-like environment. Linux users should be able to build the toolchain natively, while Windows users should install and use MSYS2 or WSL.
The process of building and installing the toolchain is done in four stages, denoted by the four subdirectories. See each of the subdirectories' README files for details. After all stages are complete, the toolchain will be completely installed and ready for use.
The toolchain will be installed at /opt/clownmdsdk. The simplest way to use
the toolchain is with a Makefile: by adding the line
include /opt/clownmdsdk/cartridge.mk to the start, the CC, CXX, CPP,
AS, CFLAGS, CXXFLAGS, LDFLAGS variables will all be configured to use
the toolchain, and the rest of the Makefile can be written as it would be for
any other platform.
