An open-source handheld game console built around a Lattice ECP5 FPGA that uses a custom hybrid 2D + 3D graphics engine capable of DS-era 2D-and-3D gameplay at a locked 60 fps. Most open-source consoles are 2D-only or software-render 3D at sub-60 fps. The goal is a powerful yet accessible, fully hackable platform for the retro-hardware community.
