ZamGBA: An homebrew SDK for GBA

 🎮 ZamGBA: A homebrew GBA game SDK written in Zig

This page contains two demos:

1. Pong.gba: A classic pong game compiled for the Game Boy Advance, running at a smooth 60 FPS.
2. Flappy Tsetseg: A simple "don't hit the wall" flying game with animation created by my daugher.

All the demos are built from scratch using ZamGBA (https://github.com/tsetseggames/zamgba) , — an open-source SDK and 2D engine written in **pure Zig (0.16.0)**.
