Raycaster for the CASIO fx-CG50. It supports simple, 2D-array based worlds with alpha-masked sprites at arbitrary positions.
There is no objective or gameplay loop, just a world you can move about in.
This project uses the PrizmSDK's build system and a few provided syscalls. You find the source here. The C standard library implementation isn't used - I rely mainly on templates and constexpr.
If you want to build this project yourself, download PrizmSDK and drop this project into (SDK root)/projects/. Use the build scripts in (project root)/scripts/ to build (no additional dependencies required).
I wrote some interactive tests so that I could debug critical code quickly without leaving Windows using a proper debugger. This is the only bit that uses Visual Studio. The code also depends on wxWidgets, installed through vcpkg. It is cross-platform, but would need a cross-platform build system.
