Searching the local listings and this showed up anyone know if its real or if its been documented before?

Best place to ask is going to be over on NA, but then that could cause other problems.

Looks legit but the only way to be 100% is to actually open up the cartridge and check the PCB.

I collect Famicom rather than NES so sorry I can’t be of more help.

Seeing how NWC Grey has been selling for over $10k lately, I’d be very suspicious of a craigslist posting. Odds are very good those are just stolen pictures.
