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.
The boards with the socket are useful for people that have a ROM chip programmer. I recommend a TL866 programmer to read and write data on the AT49F040 flash chips. You will also need a PLCC-32 Socket to DIP-32 Adapter. Both of these components are readily available on Amazon, eBay, or other online retailers.
I also sell a version without the socket for those with 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!
