Disable NES CIC w/ Jumpers???
.png)
I really dislike modifications that cause damage to the original components and cannot be undone. I remember seeing a post somewhere on the Internet where instead of cutting pin 4 on the CIC, they simply added two jumper wires to the board which ultimately disabled/bypassed the CIC.
Attached is the picture I saved from the post. I wanted to verify that this works but cannot find any other mention of this type of mod being used to disable/bypass the CIC. There is a video on YouTube but the instructions there do not match what is in the picture. Here is the link to that video:
Can anyone offer some insight?

I saw this in google images, said remove CIC first
That was posted in a NintendoAge thread I will dig up. I believe you're basically rewiring it to be like a Famicom or an NES-101, which do not have the CIC at all.

You shouldn't just cut pin 4 of the lockout chip, you should remove the chip entirely. Here is the right way to do it :
You remove both the lockout chip and the clock crystal X2. You shift one of the leads of the 1MOhm resistor as shown, add the two wires as shown and then add a 100KOhm resistor as shown. This will allow games like Super Mario Bros/Tetris/Nintendo World Cup and the real NWC cart to function perfectly.
So that actually allows the special reset functionality of those specific games to work correctly (they wouldn't even work correctly on an unmodified top-loader NES-101.
