Abstract The Rockchip RK3032 system-on-chip (SoC), originally designed for low-cost smart displays and IoT devices, has recently gained attention in the retro-gaming community due to its extremely low price and availability on surplus hardware. This paper documents the process of porting EmuELEC—a lightweight Linux distribution optimized for emulation—to the RK3032 platform. We discuss the architectural limitations of the dual-core Cortex-A7 CPU and Mali-400 GPU, present solutions for bootloader customization, and evaluate performance across several emulator cores (NES, SNES, PS1). Results indicate that while the RK3032 is viable for 8- and 16-bit emulation, memory bandwidth and GPU driver instability pose significant hurdles. We release our build scripts and kernel patches to support further experimentation.

Introduction The retro-gaming emulation landscape has traditionally relied on mainstream SoCs such as the Amlogic S905X or Rockchip RK3326. However, the RK3032—a 2016-vintage chip found in streaming dongles and cheap tablets—offers sub-$5 pricing and a minimal PCB footprint. EmuELEC (v4.6+) provides a turnkey emulation environment but lacks official RK3032 support. This work aims to fill that gap by detailing a functional port.
