I know there are about 20 of the original NES games that came with built-in Famicom converters. For those of you that weren’t already aware of this fact, basically, what Nintendo of America did was take the original Japanese PCBs from the Famicom games and add them onto an adapter that contained a lock-out chip so it could only be played on North American system. And is also essentially why American NES carts are so much bigger than Famicom carts. Anyway, of those original games with the adapters, the Japanese PCB would contain either the standard CHR and PRG mask roms, or black blobs – the latter I tend to see far more commonly. What I have never seen, until now, was the picture below.

I opened up my Pinball because I wanted to use the adapter for something else, but I immediately changed my mind once I saw the board. I have never before seen a Famicom board that looked like this, let alone any Nintendo game that had 2 PRG mask roms.

I did a little research and checked around to see if good ol’ Google would turn up anything, even just a picture of a similar board. Couldn’t find anything, so I just figured I’d share. I guess I’d like to know if anyone else has any games like this and just how common/rare these are.
