Core Native GBA

This project is a basic micro-gameengine to run lua in the Nintendo Game Boy Advanced, which can be expanded to a custom engine, such as Gly Engine.

⚠️ Attention
there is no sanitization, error handling or observation of resource consumption, all of this takes up precious CPU time, bad code will make the game crash with a black screen. I recommend made a multiplatform game that support desktop especially for testing lua code!

How to build

• i will recommend using the devkitpro/devkitarm container if you do not have devkitpro installed.
