A homebrew Game Boy Advance game made for GBA Jam 2021.
The game is a space shooter where you complete various missions. These missions take place in the solar system.
This game is in a state of development (i.e. any build thus far can be considered a development version as the game is not feature/content complete).
This game is also avaliable on itch.io.
This game was made using GValiente's Butano engine).
Butano is a modern C++ high level engine for the Game Boy Advance.
To run the game, download a GBA emulator and point it to the .gba file.
The Butano Docs recommend mGBA and the debug version of No$gba for testing during development.
For developing GBA games, mGBA and the debug version of No$gba are recommended.
This doesn't mean these GBA emulators are just tools for development, they can be used to just play GBA games. The Butano Docs refers to the debug version of No$gba for the purpose of development testing but No$gba also has a gaming version for just playing GBA games.
Alternatively, any hardware that runs .gba files on an actual Game Boy Advance (e.g. Everdrive or EZ-FLASH) can be used to run Solar Guard on a GBA (or DS with backwards compatibility).
If you have a modded 3DS, the .cia file made using Ultimate GBA VC Injector for 3DS by Asdolo can be used to install Solar Guard as a Virtual Console GBA title.
Running the .gba file using a GBA emulator that runs on the 3DS also gets the job done.

The Getting started page in the Butano Docs explains how to setup Butano.

A guide walking through my process for composing the tracks in Beepbox, exporting them to MIDI, then using OpenMPT to convert that MIDI to Impulse Tracker files that can be used with Maxmod/Butano is available here: https://rentry.org/beepbox-gba-music
