This guide shows you how to mod your super nintendo region free without a switch and with new LED lights.

btw. This mod doesn't work on 1 Chip SNES or SNES Mini, only works on original 2 Chip SNES. Check for text on the board to confirm your model.

Tools: Gamebit 4.5mm; Phillips #2 Screwdriver; Tweezers; Double-Sided Tape; Desoldering Pump; Metal Spudger; Universal Programmer; Flush Cutter; Soldering Iron; Desoldering Braid

Parts: Wire Wrapping Wire; Heat Shrink Tubing Assortment; Resistor 220 Ohm; 5 mm Through-Hole 3Pin Led Light, Red-Green Dual Color

Step 1

• Remove the two Phillips two 11.6mm screws that connect the front shield to the motherboard.

Step 2

• Lift the front shield straight up to remove it from the motherboard.

Step 3

• Remove the two silver 15.6 mm Phillips #2 screws on either side of the 62 pin connector.

Step 4

• Remove the 11.8 mm Phillips #2 screw near the rear of the SNES.

Step 5

• Lift the motherboard straight up to remove it.

Step 6 :: The Two Chips

• The Two Chips that you need on your Super Nintendo
• NOTE: This mod only works on original Super Nintendo with 2 Chips, this mod doesn't work on the 1 Chip Snes.

Step 7 :: The Lockout Chip

• Remove the Lock Out chip (use the solder gun (https://www.ifixit.com/en-ca/products/desoldering-pump))
• REMINDER: After removing the lock out chip there will probably be leftover of solder where the chip used to be so try to remove the soldier as good as you can
• NOTE: To remove the solder leftover, you can use the soldering iron and solder wick.

Step 8 :: PPU 2

• Lift up the PPU2 Pin 30 from the Motherboard

Step 9 :: PPU 1

• Now lift up Pin 24 on PPU 1

Step 10 :: Wire Time

• Wire the lifted pins (PPU 2 Pin 30 & PPU1 Pin 24) together
• NOTE: You need to use a Soldering Iron to wire the pins together
• NOTE: You can also use tape to hold the wires down to the motherboard

Step 11 :: Program

• Now you have to put the PIC16F630 Chip into the programmer and Flash the chip with the Super CIC File.
• File can be downloaded here: http://sd2snes.de/files/supercic.zip (http://sd2snes.de/files/supercic.zip)

Step 12 :: The Pins

• Bend the pins outwards
• Then clip the pins
• Use double sided tape and put it on top of the CPU and put the Super CIC on top of the double sided tape.

Step 13 :: The Wires

• Pic 1: Solder a wire from Super CIC Pin 12 to PPU1 Pin 24
• Pic 2: Solder a wire from Super CIC Pin 14 to SWRAM Pin 64
• Pic 3: Solder the 10k Ohm Resistor to the pin 8 (where the old CIC used to be) and to SWRAM Pin 33

Step 14 :: The Wires Part 2

• Pic 1: Solder a Wire from Super CIC Pin 1 to 4 on the same chip.
• Pic 2: Solder a wire from Super CIC Pin 1 to the CPU Pin 1
• Pic 3: Solder a wire from Super CIC Pin 13 to the End Point of the Resistor

Step 15 :: The Wires Part 3

• Pic 1: Sother a wire from Super CIC Pin 2 to S-CLK Pin 6
• Pic 2: Sother a wire from Super CIC Pin 11 to Old CIC Pin 10
• Pic 3: Sother a wire from Super CIC Pin 10 to Old CIC Pin 1

Step 16 :: The Wires Part 4

• Pic 1: Solder a wire from Super CIC Pin 9 to Old CIC Pin 2
• Pic 2: Solder a wire from Super CIC Pin 8 to Old CIC Pin 11
• Pic 3: You've soldered most of the wires now, lets go to the LED Mod

Step 17 :: The LED Mod

• Plug out the controller ports and solder out the LED Light.
• NOTE: When the solder points have been desoldered, you can use the tweezers (https://www.ifixit.com/en-ca/products/tweezers) to pull out the led light
• Sother on the new LED Light with the middle pin on the left solder hole
• CAUTION: Do Not sother the middle pin on the LED Light to the right solder hole as it will then be stuck in only one color!

Step 18 :: Led Resistors

• Solder 2 wires on the left and right pins on the led light, green wire on the left pin and red wire on the right pin.
• After that you should put the wires into one heat shrink tube each, remember to heat the heat shrink tubes when its over the pins.
• Then you have to solder the 2k Resistor to the red wire and the 220 ohm Resistor to the green wire.
• Then the last thing you need to do is to solder a wire from Super CIC Pin 7 to Pin 14.

Step 19 :: The End

• You're Now Done! You just need to put your Super Nintendo back together and then you have a Region Free Switchless Super Nintendo!
• Green Light (PAL)
• Red Light (NTSC) [For American and Japanese Games]
• Orange Light (Auto)

Conclusion

To reassemble your device, follow these instructions in reverse order.
