libgodc: Go Runtime Implementation for Sega Dreamcast Development
By
drpaneas
A baker's-dozen of insight crammed into one ring.
Summary
libgodc is a specialized Go runtime implementation for the Sega Dreamcast gaming console, designed to work within the platform's hardware constraints (16MB RAM, single-core SH-4 CPU, no operating system). The project replaces the standard Go runtime with one that provides core Go features like garbage collection, goroutines, and channels for Dreamcast development. It requires Go 1.25.3+ and integrates with the KOS (KallistiOS) Dreamcast development environment using gccgo.
