Dependecies

ImGui: https://github.com/ocornut/imgui
SDL2: https://github.com/libsdl-org/SDL/releases/tag/release-2.26.5

In order to build the project, create a lib directory in the project root. Then download ImGui from the Github link above and place it in the lib folder. For MSVC users only, place the SDL2 library folders into the lib and name it SDL2. For Unix and Apple users, CMake should automatically find the SDL library.

Building

Create a build directory and use cmake to build the project.

mkdir build
cd build
cmake ..

To-Do List

• Currently, there is no memory bank controller implemented, so only 32KB ROMs are supported. I plan to implement MBC1 at the very least.
• Improve the cycle accuracy of the CPU. Not really needed, but is something to do.
• Audio.
