Game Genie for SEGA Game Gear Repair:
I bought a non functioning Game Genie for Game Gear because it was very cheap, though unfortunately it is missing its mini code book and the flap that held it inside the Game Genie.:
To open it up to see what is going on we need to remove two screws at the top on the front of Game Genie:
Then remove the 6 identical sized screws from the rear of the Game Genie around the edges:
Then finally remove two shorter screws from the cartridge:
You can then lift the front off the Game Genie (but be careful not to lose the button):
Flip it over and then remove the rear of the case (again be careful not to lose the button):
Leaving:
You can now lift up and out the cartridge PCB as it is connected just by a socket:
Flipping it back over we now need to remove the clear plastic piece that is connected to the cartridge connector with two more screws:
Once that is lifted off everything is now free:
And you can lift off the main PCB:
Leaving:
Which is actually two separate pieces of plastic:
I removed the single 47uf 10v Capacitor:
Testing it in my ESR meter showed me that its ESR was very bad:
So I replaced it with a new one:
Then I cleaned the cartridge contacts and the the contact pads for both buttons.
After re-assembling it, I tested it again and it came back to life:
Only 10 more logs to post until I hit 50…
