Second Bedroom publishes Game Bub, an open-source FPGA handheld developed by Eli Lipsitz for Game Boy-family cartridges, homebrew ROM loading and hardware experimentation. The production device combines an AMD Xilinx XC7A100T with an ESP32-S3. Its public repository carries current firmware and FPGA source plus archived revision 2 hardware design files under reciprocal open licences. Flashable links the shipped revision 4 handheld to its official v1.0.1 update path. Buyers should distinguish this horizontal production unit from the older vertical revision 2 design referenced by archived self-build material. The optional dock is a separate product, and the firmware release asset names the hardware revision it supports. Follow each device into original project sources, compatible firmware and practical guides.
