From the project

My own version of RetroReboot's MBC3 flashcart https://www.retroreboot.net/HTML/projectpage.html, please consider supporting him if you can https://www.paypal.com/paypalme/WadeVillines

MBC3 Flashcart based on retroreboot's cartridge that uses 0603 components (while based on the RetroReboot carts, these are completely redesigned from the ground up in kicad)

If you want a 4MB cart check out my new MBC30 flashcart repo

Version 1.5 and beyond makes use of djedditt's cartridge connector footprint

As a disclaimer, i get 10% kickback on shared pcbway orders, if you want the cheaper option go with either JLCPCB or OshPark
