ZamGBA: a Zig-based SDK aims to simplify Game Boy Advance homebrew development

Developer fuzhouch released the first version (v0.1.0) of ZamGBA on August 23, 2026, a lightweight SDK and 2D engine written entirely in the Zig programming language, aimed at Game Boy Advance homebrew development. The project is freely available on GitHub.

ZamGBA relies on a two-layer architecture: a hardware abstraction layer (HAL) that talks directly to the console's processor, and a game engine built on top of it. Features already present in this first version include automatic generation of GBA headers at compile time with no external tools required, support for 24.8 fixed-point numbers with compile-time conversion, hardware interrupt-driven VBlank sync, and 2D AABB collision detection along with controller input handling.

An early but functional foundation. The project's author acknowledges this is an early release: ZamGBA doesn't yet have audio drivers or support for scrolling backgrounds. Still, a fully playable Pong game serves as a technical demo in the repository, proving that the HAL and engine already work correctly on both real hardware and emulators.

The choice of Zig, a still-young language increasingly popular with the homebrew scene for its fine-grained memory control without unnecessary complexity, places ZamGBA alongside projects like ZigGBA, though with an approach focused on a full game engine rather than a mere set of hardware bindings.
