Changelog:
1.1:
- Rewired WE on the ROM chip to Pin 31 on the cart bus to fix an issue where it would not write to a bank.
1.2:
- Changed the PCB to fit inside Japanese Pokemon Crystal shells
- Added inverted silkscreen to the board to make it look more like the original
- Added Crystal Clear edition
1.3:
-
The pinout for the MBC30 listed online is wrong, thanks to Alex over at InsideGadgets for providing a fixed MBC30 pinout.
-
Removed the front silk screens as most manufacturers struggle to make it.
1.3.1:
- Moved C2 to make it easier to close the shell
1.4:
-
Switched cart bus footprint to djedditt's replica of an original one
-
Replaced the flash chip footprint with a TSOP-40 footprint.
-
Redid the ground plane by hand, it should now look much better.
-
Moved the battery receptacle footprint 0.5mm to the left.
-
Renamed Y1 to X1
-
Removed JLCJLCJLC marking for OSHPark project.
1.4.1:
- Fixed missing trace for Ram_CS
1.4.2:
- Fixed a symbol kicad "rescued" causing the pinout to be backwards (this put the chip direction indicator in the wrong corner)

Questions
How big is the Mbc30flash PCB?
It measures 51 × 60.2 mm and has 2 copper layers, 0.8 mm thick.
What parts does the Mbc30flash use?
19 parts, built around the 74LVC1G332GW,125 and FM18W08-PG. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Mbc30flash KiCad files?
From the HDR/MBC30-Flashcart repository on GitHub, at the commit this page was made from: the board is KiCad/mbc30flash.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mbc30flash design in my own project?
Its repository states no licence, so its author keeps all rights: ask HDR before reusing the design.
