This is a game for the original Game Boy console, created to learn about making Game Boy games.
Development was done on a Ubuntu 20 Linux PC. It is assumed a similar environment is used. It's likely other environments could work as well.
git clone gbdk-2020 from https://github.com/gbdk-2020/gbdk-2020 to somewhere on your PC.
Set environment variable GBDK_HOME to the root of its directory tree.
This is used by the music driver hUGEDriver
https://github.com/gbdev/rgbds
The rgbasm application should be available in $PATH
These are available from https://github.com/gbdk-2020/gbdk-2020-sdcc/releases - download a binary distribution appropriate for your PC, and set envionrment variable SDCCDIR to where this has been extracted
Run cmake -DCMAKE_TOOLCHAIN_FILE=cmake/lcc.toolchain.cmake -Bbuild && cmake --build build

Expect a cartridge ROM to be produced at build/robot_quest.gb. Load it into a
flash cart and place it into a Game Boy, or load it in your favourite Game Boy
emulator.
This project was created from a gbdk-2020 template, which included the following readme:
A template project with a Makefile that supports sub-directories.
The Makefile will automatically detect and compile new source files when they are added to the "src" and "res" directories.
Project directories
- src: Main program source files (.c, .h, .s) can go here
- res: Program graphics and audio source files (.c, .h, .s) can go here
- obj: Compiled ROM (.gb) and debug files go in this directory
