Something Old School
SuperCIC 50/60hz Switchless Mod Chip Installation Guide
This instruction will guide you through the process of installing the Something Old School SuperCIC 50/60hz switchless mod chip into your Super Nintendo and will allow any game from any region to be played.
First thing we must remove the main PCB from the case. Im going to assume that if you are able to tackle this task that you already know how to disassemble a SNES.
Once the you have the main PCB removed from the case we must remove the CIC chip.
Using a good soldering iron with some desoldering braid I remove as much of the solder as possible from the pads. Then with a heat gun and a lot of patients I removed the CIC chip. NOTE: I also removed the reset switch before using the heat gun just to safe. Plus the reset switch being out of the way will help when soldering the wires of the SuperCIC to the CIC chip pads.
Next one pin from each of the two PPU chips needs to be lifted. Pin 24 from PPU1 and Pin 30 from PPU2.
Extreme care must be taken when lifting these pins, they are very delicate. I use my iron at the end of the pin to heat the solder and then use a razor knife to lift the pin.
Now that the old CIC is removed and the PPU pins are lifted we can install the new SuperCIC chip.
I use a little bit of super glue and glue the SuperCIC board to the CPU chip. Once the SuperCIC chip is in place the main wire harness may be plugged in and you may begin soldering the wires to the CIC pads.
First thing to do is solder the Violet wire to PPU2 pin 30 & PPU1 pin 24. I also use a little hot glue to keep the pins in place and hold the wire to keep it all from moving or breaking the pins.
The three Black wires go to ground and may be soldered any place there is a good ground. The rest of the wires are soldered to the pads where the original CIC was and are soldered to the pads as follows…..
Black = Ground
Brown = Pad 7
Yellow = Pad 18
White = Pad 8
Green = Pad 10
Gray = Pad 1
Purple = Pad 2
Orange = Pad 11
Here is what everything should look like once your finished connecting it to the PCB. Once its complete the Main PCB may be reinstalled into the SNES.
Next the Bi-color Red/Blue LED must be installed into the front panel.
To get to the led on the NTSC SNES the P1 & P2 controller ports must be removed from the PCB.
Once the controller ports are removed we can remove the old LED and the 160 ohm resistor.
When the old LED & resistor have been removed bend the anodes of the new LED 90 degrees at the LED base and slip the cathode through the negative DIP on the PCB.
Using a razor knife or instrument of your choosing notch out the plastic so that the anodes of the Bi-color LED with pass through.
When you are happy with the fitment re-solder the controller ports back in place, solder the cathode of the new LED into place and reinstall the front plate back into the SNES.
Once you have the front panel in place bend the anodes of the LED over the PCB and connect the plug on the LED to the plug on the SuperCIC board.
The last thing to do now so that we can physically insert PAL & Super Famicom carts into the NTSC SNES is to remove the small tabs inside the cartridge slot.
Using a pair of cutters and a Dremel I removed the tabs from inside the cartridge slot so now all carts may be inserted. Once the tabs have been removed reassemble the SNES and enjoy playing games from any region on 50 or 60 hz.
Once the SNES is powered on it will boot in 60hz mode. The modes are changed by holding down the reset button and waiting for the LED to change color. RED is 60hz mode BLUE is 50hz mode and PURPLE is auto detect mode. In auto detect mode the SuperCIC will automatically detect the cart inserted and set the hz mode for the type of cart inserted.
