As with all of our TUTORIALS, please comment with any information that you think should be included - we don't pretend to know everything, the modding scene has evolved into what it is today due to the great community that supports it and the free sharing of information. Any suggestions later included in our tutorials will be credited at the bottom of the post - leave your Instagram account to be featured!

 

This tutorial documents the steps to install our BIVERT BOARD into an original Nintendo Game Boy.

We will presume at this point that you have opened your Game Boy and have in front of you the rear PCB (DMG-CPU-0X).

You will need:

Soldering Iron

Solder

Desoldering Braid (optional but helpful)

A pin or pointed craft knife (anything with a fine tip that is reasonably strong)

Flux (optional but helpful)

Step 1: Lift the LCD Connector Pins 15 & 16

A bivert mod works (very basically) by intercepting the signals to the LCD and inverting them.

Pins 15 & 16 on the LCD ribbon connector carry these signals and to add our Bivert Board you must first interrupt the signal flow between the CPU and these points.

Locate pins 15 and 16 on the LCD connector - count up from left hand side or down from 21 on the right hand side.

Place your desoldering braid across the pins.

Use your soldering iron to apply heat between the two pins until you see/feel the solder liquify and soak into the braid - be careful not to affect any other pins on the connector!

Use a fine pair of tweezers or a pin to gently lift the pins from the board.

NOTE: you may need repeated use of desoldering braid to remove all of the connecting solder - If the pins do not freely lift you can apply heat with your soldering iron at the same time as lifting the pins.

Step 2: Position Bivert Module

It will help to take a pair of flush cutters and remove some of the leg protruding through the solder points that match the holes on the left hand side of the Bivert Board.

Adding a small amount amount of solder (or flux if you have it) to each connection you are about to make also helps.

Position the board as pictured making sure that the two LCD pins are free from contact with the DMG PCB and that the bivert board can sit under them without a problem.

Check that all 4 holes are sitting above their intended connection and that the LCD pins line up with the solder pads on the Bivert Board.

Step 3: Fill Holes and Connect LCD Connector Pins to the Module
