Introducing Game Bub: An Open-Source FPGA Handheld for Retro Gaming Enthusiasts
Introducing the Game Bub, an open-source FPGA-based handheld console designed to play Game Boy, Game Boy Colour, and Game Boy Advance titles. Developed over a year and a half by engineer Eli Lipsitz, Game Bub offers a blend of nostalgia and modern tech, allowing users to enjoy classic games directly from original cartridges or via ROM files stored on a microSD card.
A Modern Take on Classic Gaming
Game Bub stands out by supporting physical cartridges, enabling players to relive their favourite games as they were originally intended. Additionally, it offers emulation capabilities, allowing ROM files to be loaded from a microSD card for convenience. The device also features compatibility with the Game Link Cable in both Game Boy and Game Boy Advance modes, facilitating multiplayer experiences.
Feature-Rich Design
Beyond basic gameplay, Game Bub boasts several enhancements:
• Video Output: Connect to larger screens via HDMI through a custom dock.
• Immersive Feedback: Incorporates a rumble motor for tactile responses during gameplay.
• Real-Time Clock: Supports games that utilise time-based events.
• Extensibility: Designed with future expansions in mind, allowing for software updates and additional features.
Technical Specifications
At its core, Game Bub features a custom-designed six-layer PCB housing a Xilinx XC7A100T FPGA with integrated memory. The handheld includes a vibrant display, built-in speakers, a rechargeable battery, and a GB/GBA cartridge slot, all encased in a custom 3D-printed enclosure.
Open-Source and Community-Driven
Emphasising accessibility and collaboration, the project’s instructions, code, and design files are available on GitHub.
