Cord works like a charm!

With this set up I've had a few graphical issues, however, I'm positive it's the cheap upscaler not the cord

This cord works great with the n64 system and has a much higher quality video output than the standard av cable originally paired with the system.

Love this cord, it replaced my old one after my cat chewed it up.

Both Y/C had their own grounding pins on the Nintendo connector like the original Nintendo cable
