MBC30 Flashcart for 4MB roms

BOM

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)

Replace your broken Fire Red / Leaf Green pcb

This is a custom pcb designed specifically to look like an original Cartridge PCB

A board that converts a wired 360 controller to USB-C

BOM:

TYPE-C-31-M-12

1x5 2,54mm pitch header

Resistor 5.1K x 2 (only required if you want USB-C to USB-C)

Changelog 1.4:

• Replaced usb c socket with something way better.

A tool for dumping the flash of a JoeyJoebags Gen3, just solder an angled female header, plug in a CP2102 and run stm32flash.
