Not that I'm aware of. I looked and I cannot find a reference of that. If it was it would've been an NES instead of a Famicom. Nintendo just officially started supporting Malaysia in 2006 and looking at pics of the game counters, the games are in NTSC US format. I saw the ESRB ratings on the packaging and the US is the only one that uses those ratings.
The NES was only released as the Famicom in Japan, the Philippines, China, Vietnam, and Singapore.
But, you're right on a possibility. Maybe he modded it for PAL. But, if so, you would get a COMPLETE image, it would just either roll or be in Black and white.
