To address the lack of hardware sovereignty in proprietary console ecosystems, this paper presents a fully open-source RISC-V gaming platform utilizing a VexRiscv core and Lattice ECP5 FPGA. We implemented a custom SoC featuring dedicated 2D GPU and APU accelerators, supported by a complete LLVM-based toolchain and a high-level Game Development Framework API. Validation through a 48-hour game jam demonstrated the platform’s utility, achieving a stable 640 × 480 at 60 FPS output and high power efficiency for independent development.
