Game Gear replacement mainboard 315-5335 v1.2
This is a brand-new manufactured replacement mainboard for your Sega Game Gear, using all new components. This board makes it possible to repair your VA0 model Game Gear which suffers from PCB damage caused by leaking capacitors or batteries.

The board has been reverse engineered from a Sega Game Gear VA0 model, better known as the DUAL-ASIC variant. Since I am not able to source new ASIC chips, cartridge connectors and expansion port connections, you need to supply these parts from one of your broken boards. TV-tuner is not supported - this is limited due to the current available LCD kits.

The board has not been fully tested with all LCD kits, the following combination is tested:

  • SEGA 315-5378A and 315-5378B chip ASIC revisions
  • SEGA 315-5378 not working (only used on very first Japanese mainboards 837-7398-01)
  • BennVenn IPS kit
  • RetroSix Cleanscreen v2
  • GGLCD
  • Funnyplaying v3.1
You need to harvest and assemble the following chips:
  • IC1 Toshiba 84C00AM-6
  • IC2 SEGA 315-5377 VDP ASIC
  • IC3 SEGA 315-5378A or 315-5378B SCA ASIC

Installation is done at your own risk. I do not take responsibility for damage resulting from installation. Experienced soldering skill is needed – do no buy this kit if you do not know how to solder fine pitch SMD chips.

Before installation, please join the BennVenn discord via https://discord.gg/f8AbftjEMs and look for the #game-gear-mainboard-kit channel!
