This circuit enables the user to play their own .ROM files using an actual Gameboy - no more software emulators! The user-programmable ROM is a AT49F040, a 4 megabit flash chip. This means the .ROM file to be programmed cannot be larger than 512 kB, which excludes some of the larger ROMs out there. This circuit uses a salvaged Nintendo MBC1 (Memory Bank Controller), to allow 100% compatibility with official hardware. This PCB does not have the circuitry for battery-backed saving in RAM of high-scores or settings.
This circuit is perfect for anyone that wants to play a custom or homebrew game or application on a real Gameboy.
Original Game Boy cartridge case is included with either of the Fully Assembled versions.
Please contact me before or immediately after ordering if you would like me to program the ROM before shipping. I also have extra ROM chips available for sale for use with the socketed version.
Update 9/26/16: I'm switching up the product variants now that I've been selling this product for a couple years and have seen what people buy. I am currently out of stock of the bare PCBs, but will order more ASAP. Right now there are just 2 options: Assembled without socket or Assembled with socket. I only have a limited number of the boards with the socket and once they're gone, I do not plan on producing any more. The boards with the socket are useful for people that have a ROM chip programmer. I have found that the majority of people have a Game Boy cartridge programmer so they can just plug in the cartridge and program it without messing around with the ROM in the socket.
Please use the "Contact Me" form underneath my profile photo to the right with any questions, and I'll respond as quickly as possible. Thanks!

My girlfriend lovingly refers to me as a "tinkerer” because I spend my free time designing and building electronic circuits. I also have a Printrbot 3D printer and enjoy creating objects layer-by-layer. I love microcontrollers and writing code (and learning new programming languages) and have many hobby projects that take advantage of that. I have more ideas than time so I’m always switching between projects. I love taking a project from an idea, to a design, to a physical product. Nothing beats having a functional device that you've worked on from start to finish.
I graduated with an electrical engineering degree from the Pennsylvania State University. I am now an employee at Hughes Network Systems working in the hardware division creating and testing new designs for broadband satellite modems.
