This is a very simple demo of a fixed-point raycaster for the fx-CP400 with texture and sprite support. To run it, you will need the hollyhock SDK.
Copy the .hh3 file into the root directory of your calculator and launch it through the hollyhock menu.
Easiest way to start is to fork this repo and to open in GitHub codespace (in the clone menu), or locally on a devcontainer (VSCode would prompt to use them when openning the repo).
For advanced users, it is possible to use docker locally. See: Getting Started in V3
Then just run make in the projects directory.
