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
1.3:
- The pinout for the MBC30 listed online is wrong, thanks to Alex over at InsideGadgets for providing a fixed MBC30 pinout.
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)
