working with electronics. At the time of this guide’s writing the AGB 001 handheld are rapidly aging, and even
working units should be recapped as soon as possible. Chemicals associated with some of these processes are
quite toxic and should be handled with care and adult supervision. Results may vary. “GBHD”, “GBHD Advance”,

Section 1: Pre-Tinning the GBA PCB
Aer extracting the GBA PCB and removing the speaker ip the board over to the side with the system’s proces-
sor is located.
Pre-tin this corner of the processor including the large ground plane as it is also an anchor point for the ex
cable. Desolder the battery terminals.

Section 1 Continued...: Pre-Tinning the GBA PCB
Additionally, tin Pin 32 of the cartridge
connector and both of the pads next to
CL1
Page 5
“Be gentle and condant when tinning the
GBA CPU legs, ux is your friend.
Let science take the wheel.”

Section 2 Soldering the Flex Cable
Bottom row pins
1 = 3.3v
3 = right trigger
4 = A
5 = B
6 = SO1
7 = SO2
Le row pins:
127 = start
126 = select
123 = right
122 = down
121 = le
120 = up
119 = le trigger
Ground Points
Ground Plane
32 = ground
CL1 = ground
Page 6
Have the pins from the ex cables as close to the pins of the GBA processor as possible. Solder the
ground plane at the corner of the GBA processor. Once the pins are aligned solder pins 7 and 119. Further
secure the ex cable by soldering pin 32 of the cart slot and the two solder pads near CL1. Apply genourous
amounts of ux and drag solder the rest of the pins with a loaded soldering iron. Wick any bridges that form.

Section 3 Connecting R16 to S2
Connect a single wire from the bottom of R16(located near the USB port of the GBHD Advance) to S2 on the GBA PCB(located
near the right side of the cart pins.)

Section 4 Connecting the FLEX and VIDEO cables
Now that both PCBs are tied together with a wire, start making the connections of the ribbon cables.
e GBHD Advance side of the ex cable will require a gentle “S” bend to make its connection, the GBA
side of the ex should be secure enough that it won’t li.
Insert your 32 (or 40 pin) ribbon cable where the
LCD used to attach.
Connect the other end of the cable to the GBHD
Advance PCB.

Section 7 Assemblly
Insert the button plunger into the bottom housing.
Now gently rock the two PCBs into place so that the GBHD Advance’s power button and controller ports
click into place. e wires should all fold in quite easily. Begin fastening 4 of the shorter screws in a star pattern
before hand tightening .

Section 7 Continued...: Assembly
Page 10
Manuever the GBA PCB into position above the GBHD Advance PCB and fasten it down with another
4 short screws. Making sure not to pinch any of the cables and watching that our holes are clear. Fastening them
lightly before tightening in a star pattern, as was done with the lower board. Make sure the shoulder buttons are
clear of the case.
To complete the install, fasten the case halfs together
using the 4 long screws.

Section 8 Optional LitKit Installation
First locate and then remove the resistor at R15 and the LED located at LED02 on the GBHD Advance
PCB.
Next connect the 3.3v and the Ground from the LitKit PCB to these points on the GBHD Advance PCB
to these points at the highlighted power regulator.
3.3V

Finally connect the Data pin from the LitKit PCB to either of these highlighted points from R15, or
LED02. LitKit is compatible with the WS2812B addressable RGB LEDs, up to 10 for further customization. Easi-
ly integrated into other 3.3v logic.
