SEGA Mega Drive / Genesis Cartridge PCB v3.5

    €5.00 – €32.00

    SKU: segamdrvgenpcbv35-1 Categories: , , Tags: , , , , , ,

      This is a printed circuit board (PCB) for non battery save Sega Mega Drive/Genesis games. If your game has a broken board, or you want to play a ROM hack on actual hardware, this is for you. The board is designed to take CMOS EPROMS or NOR Flash chips, details are listed below.

      When using the EPROM chips, a solder bridge must be closed on the back, R1 if it’s a 4Mbit, 8Mbit or 16 Mbit, or R2 if 32Mbit is used. The NOR Flash is not supported for anything over 8Mbit, so no solder bridging is required for this.

      While game saving is not supported on this PCB, games that do use battery backed memory(or FeRAM) will still play fine apart from the save feature. 

      To select the memory size it is not necessary to solder any wires, there are jumpers on the back of the board that can be bridged with solder(you can use solder and wire if you prefer). 
      You can install a socket if you wish use the PCB as a test cart and swap in different ROMs/Games as needed. 

      Info:

      – Ideal for maintenance of cartridges with oxidised or damaged contacts.
      – Gold PCB fingers.
      – This version does not have a save feature or battery backup. Most games do not use this anyway (see SegaRetro.org for more details).
      – Does not come with a ROM/EPROM/Flash chip.
      – Capacitors are not included with the bare PCB(they can be added from drop down menu above if required).
      – Requires some basic soldering skills to install EPROM/NOR Flash/Capacitors.
      – For 4Mbit, 8Mbit or 16Mbit EPROMS, close the R1 contacts.
      – For 32Mbit EPROMS, close the R2 contacts.
      Required components:
      C1 and C2: 22uF Capacitor
      C3: 100nF Capacitor
      You can use surface mounted or through-hole capacitors.
      CMOS EPROMS:
      M27C400 – 4Mbit
      M27C800 – 8 Mbit
      M27C160 – 16 Mbit
      M27C322 – 32 Mbit
      NOR Flash:
      MX29F200C – 2 Mbit
      MX29F400C – 4 Mbit
      MX29F800C – 8 Mbit

      Gold Plating, Bevelled Edge and Chamfer

      The cartridge PCB has a gold plated surface finish and the edge connector is bevelled and chamfered.

      The chamfer and bevel reduce the insertion stress on the console’s edge connector. The gold surface finish improves conductivity, reduces wear and tear and provides a great solderable surface.
