Hello!
I haven't been here in awhile, but I had something that I thought someone would be interested in.
It's a loose copy of the Realtec Game Genie for the Famicom. I have it up on eBay, but feel free to message me here if you were interested.
Here's the eBay link: https://www.ebay.com/itm/132926128426 .
Take care!
PM sent ....but I know it's a long shot
