Game Gear Fixing

Working on fixing the sound and screen problems on my Game Gears. All got the same capacitor issues.

Easy fix with a kit from ebay.

started by removing the old caps on the sound board. They’ve even started to swell. the ones on the mainboard are looking very bad, with leaking fluid around the plastic cap holders.

Naomi Supercapacitor

Another Little mode on the Naomi is to change the “Supercapacitor” located next to the battery backup.
This little cap has a reputation of going bad, leaking and bricking the system. Its very easy and cheap to replace.

Part number is EECS0HD104H. Found on ebay for £2.50. Worth it.

Naomi Zero Key

Got the Zero Key needed to load decrypted game images in the Naomi NetDimm

I had to remove the surface plate to install the chip. The original GD decryption keys had a packaging that allowed the chip to be installed and removed easily.

Now all that’s needed is the new BIOS.

Naomi Netboot

New Project to work on alongside the Naomi Universal Cabinet restoration.

Just received a Netboot Dimm module. Been looking for this for a while now.

This will allow the Naomi to boot game data from a network computer. My plan is to use a Raspberry Pi to transfer data.

Still need a few more parts:

  • Decrypted security key for the Dimm
  • Naomi BIOS compatible with the DIMM
  • Raspberry Pi and LCD display for data loading

I’m also going to do a battery capacitor replacement on the motherboard first, as they leak over time eventually killing the board.
