Sega Genesis / Mega Drive Flash Cartridge Circuit Board

This is an unpopulated circuit board you can use to make your own homebrew Sega Genesis / Mega Drive games, or repair old games that no longer work. You will need to purchase components and solder them to the board yourself. This cartridge is made entirely from brand new off the shelf components. No donors are required, and you don't need to rely on AliExpress or eBay for parts! You can find all the information you need to assemble, configure, and program this board at my GitHub: https://github.com/MouseBiteLabs/Genesis-Cartridges/tree/main/Advanced%20Flash

These are capable of being flashed after assembly via the Open Source Cart Reader (OSCR) by sanni. Alternatively, you can also flash the ROM chips before soldering them to the board through the use of a programmer like the T48 programmer with the TSOP48 adapter. Please note that this design is NOT the same as flash carts that use an SD card to load games - these boards can only be flashed with one game at a time.

This cartridge covers over 95% of the entire Genesis library. You can backup games up to 4 MB in size, with up to 32 KB RAM. It can also handle any ROM hack that falls into these limits, including the ever popular Sonic 3 Complete. Check out the Game Compatibility page in the wiki for more info.

If you want to make a non-flashable, but easier-to-solder version of these boards, you can use the Advanced UV board.

You can find example builds at the wiki page of the GitHub: https://github.com/MouseBiteLabs/Genesis-Cartridges/wiki/Advanced-Flash

This project is open source, so if you would like to order your own from the PCB manufacturer of your choice, the files are available in the GitHub repository. Just be sure to match the exact specifications as listed (thickness, surface finish, etc).
