Natu is a package for making Game Boy Advance games in Nim.

Originally a wrapper for libtonc, we are now growing in our own direction: ditching some old conventions to be more Nim-friendly, and adding more libraries.

Features

• Full GBA memory map + flag definitions
• BIOS routines
• Interrupt manager
• A powerful text system (TTE)
• Surfaces (draw to tiles like a canvas)
• Efficient copy routines
• Sin/Cos/Div LUTs + other math functions
• Fixed-point numbers, 2D vector types
• Random number generator
• Hardware sprites, affine matrix helpers
• Color/palette utilities
• Button states (hit, down, released)
• mGBA logging functions
• Maxmod bindings for music/sfx
• Posprintf wrapper for string formatting

Usage

For docs and setup instructions go to natu.exelo.tl

The examples can be found at git.sr.ht/~exelotl/natu-examples

Happy coding! And if you need any help you can reach me (exelotl) on the gbadev discord, #natu irc channel on EFnet, or ask a question on the natu mailing list.
