I have an NES front-loader where I fried something in the "silver box" that handles power and A/V (this NES part has no consistent name in the repair/modding community, that I can tell, so I'm calling it the front loader's "silver box").

I was using poor technique with my multimeter trying to test the voltage regulator and I think I shunted 12v to ground. I have an entirely socketed NES for chip testing and all of the IC's work fine. The issue seems entirely limited to the silver box.

Rather than try and rebuild the silver box, I was thinking of seeing what "no-cut" options are out there. TheRealPhoenix used to sell Borti's no-cut NES-IO but COVID part shortages made the PIC it relies on hard to get, and he lost interest in returning it to production as certain features it had are now unnecessary (e.g., game controller activated in-game reset and palette mod changing is now available with v4 of the Tim Worthington NESRGB mod).

Does anyone know where I can order a "silver box replacement kit" that has the following features: (1) interfaces with v4 of NESRGB, and (2) uses a mini-DIN for RGB output and also has s-video output?

I know I could locate an appropriate PCB that comes with a BOM (parts list) where I could source parts separately, but I'd rather buy a kit.

A lot of the bare PCB's that are posted online seem to require trimming a corner of the NES PCB or the internal case to make it fit, or rely on cutting a hole in the brittle NES case to install a SNES multi-out)

Givent the above info, can anyone recommend either:

• a no-cut kit that is available for purchase, or, if none exists,
• a straightforward PCB that requires no trimming of the hardware or the case with a BOM/parts listing that doesn't require unobtainium

Absolute nightmare. Not just leaking batteries but several components had to be replaced on the front. Ridiculous amounts of contact cleaner in the card slot. Copper plate ground so corroded I could peel it off like wet toilet paper. Removed it and soldered all the contacts together. Bought for 5 bucks, only took about an hour to fix.

I recently picked up a syringe of Chipquik SMD291 tack flux to play around with, I'm just getting into doing smd stuff... and I find myself using it for just about everything because it's so easy to use, works a treat, and is fairly easy to clean up. What flux do you like to use? Do you have different ones for different uses, or do you tend to just use one for everything?

I love how Adrian Black shows what the scope should look like for the C64 on power on, etc. but I have never seen anyone do the same for an NES. It would be a fascinating video. Anyone seen anything like this?
