Thread starter Madmorda Start date Feb 21, Tags game cube gamecube install modchip xeno gc xenogc. Madmorda Painting Queen. There is a lot of information out there about these Gamecube modchips, but a lot of it is incorrect. Hopefully this guide will clear some of that up. What is a Xeno GC? This modchip is a tiny chip designed to go inside a Gamecube console to allow it to read burned copies of games.
It is designed to sit directly on the underside of the daughterboard for the disc drive. There are six points that must be soldered in order for this to work, and the leds built into the chip will tell you when it's working.
That way you can see where everything went exactly when putting it back together. To disassemble your Gamecube, first you will need to remove the four hexbolts on the bottom side of it using your 4. Some guides say you can melt a pen and use that to form the bit and remove the screw, but this is not recommended. After you remove those four bolts, you can take off the top half of the Gamecube. This picture is after the laser assembly has been removed so that all screwholes can be seen at once.
Remove the screws from all the places circled in blue. The fan will need to be removed in order to reach the four underneath it When putting it back together, make sure to put those in before the fan. After taking out all of those screws, you can remove the silver plate with the laser assembly still attached.
Remove these screws as well, and then you'll have access to the daughterboard underneath. Step 2: Wiring The modchip is made so that it can be directly soldered onto the circuit board. However, it is strongly recommended that you use wires to install it instead, since they are significantly easier to troubleshoot, and the modchip is much easier to remove or replace.
For doing a wired install, you will need some very thin flexible wires. A good place to look for them is inside the cables of a broken gaming controller. You will need six of them, preferably about 2" long each and in different colors to avoid confusion.
Here are the two locations we are concerned with. In the red circle is the potentiometer. We will use this later. The yellow circle is around the place we will be installing the modchip. Here are the points you will need to solder the wires to. Some of the points have more than one place they can be soldered to on the circuit board.
You do NOT have to solder to all of them, only one. The others are included in case one spot gets too messy. It is important to make sure that no contacts are bridged.
After everything is soldered in, put electrical tape underneath your modchip so that it isn't directly touching the circuit board. Put another piece on top of the modchip, but make sure that the little LEDs are still visible. If you don't insulate it before testing, it can cause an error. Step 3: Testing Before epoxying in your new modchip, you will want to test it. Put the laser assembly and the metal shielding plate back on your Gamecube, but leave the plastic top half off.
Plug it into your tv, and turn it on. You should be able to see a red light inside. It will do one of these things: 1 Doesn't light up.
If it's not, then check that your wires are all connected firmly in the right places and that nothing is bridged. As a last resort, you could replace your wires in case one of them is broken.
If you are sure it is installed correctly but it still won't light up, your modchip may be defective. Check that your wires are all soldered in the correct places and that nothing is bridged. Make sure that you have electrical tape above and below the modchip. As a last resort, you could replace your wires. See number 2. Your modchip is functioning perfectly.
Time to move on to step 4. Step 4: Laser Adjustment Once your modchip is installed correctly, it is time to make sure it can read your games. Original Gamecube games don't need as strong of a laser as burned ones, so most of the time you'll have to turn up the power on your laser. Fortunately, this is very easy due to the laser pot.
A pot or potentiometer is an adjustable resistor. In this case, it is used to control how strong the laser is and can be turned up and down using a Phillips head screwdriver.
Since it's a resistor, a higher value means a weaker a laser. A lower value means a stronger laser. Then take a burned game and see if it can read it. If it can't, the move on to the pot tweak. When testing games, you will have to hold down the two black plastic switches in the back right corner of the console. There are four Nintendo 4.
Once all of the screws have been removed, along with the front and back panels, you can lift the drive assembly away from the console's motherboard. At the bottom of the drive assembly is a metal shield with some smaller screws. Once the screws are removed you can lift away the metal shield to reveal the disc drive controller board. Now it's time to solder the XenoGC modchip to your console.
Start by finding where the modchip should be positioned on your board, and then add some flux over where you will be soldering. You should then tin each point with a small amount of solder. The picture above shows the board with flux, and the points tinned.
Now place the XenoGC onto the board, and solder each of the points in the diagram above. You'll want to heat both the solder blob on the drive controller board, and the XenoGC chip at the same time. You may need to add a small amount of additional solder. Don't add too much solder or you'll risk bridging some connections. Once you've finished soldering the chip it should look something like the two images above.
You want solid shiny solder connections. Alternatively you can use wire something like 30 AWG wire to connect the points on the chip to the points on the board. Once the chip is installed you'll want to test it. I recommend putting the console back together, but leaving the top of the console off until you verify it works.
There are status lights on the modchip that you can use to see the status of the installation. The colors and their meanings vary, but in general seeing an LED light up in general is a good sign. You can test booting backup discs, and games from other regions. There is also a XenoShell menu you can access by holding the start button on the first controller while starting a game. If your laser is worn out you may need to adjust the laser potentiometer to get it to read game backups.
