This is an updated design of my old NES Discrete cartridge boards. Functionally, this design is nearly the same as the older one, but I added compatibility for a few new mappers and expanded the available memory for some mapper types, and under the hood I have ported the project over from Eagle to KiCad and heavily cleaned up the schematic and some of the trace routings. No donors are required, you don't need to rely on AliExpress or eBay for parts, and you can make games with all brand new parts! You can also use this board as a replacement for NROM and CNROM games that have been damaged (assuming the ROM chips are still in-tact).

Please view more information at the GitHub before ordering circuit boards. All files and schematics are available, as this is open source.

As of writing, this version is UNTESTED (but v1.0 works, so this one should be fine).

Important Board Characteristics:

Thickness: 1.2mm

Surface Finish: ENIG

Gold Fingers: Yes, 30° chamfer
