Rockman 4 Gold Famicom Cartridge
Only 8 copies around. Because the carts were issued as prizes for those who won the RM4 Japanese boss design contest back in 1991.Â Design one of theÂ 8 Robot Masters (bosses in the game) and get a golden copy Famicom grail.
Notes From Link
From what I can dig up online, as of 2009 only three copies were confirmed. One on display and sale for $6,000 in the Japanese retro gaming Store Super Potato, one each in the hands of Ring Manâ€™s and Bright Man’s designers. However, the info on the ownership of the Bright Man cart dates from back circa 2004.
Also (and I can’t confirm this) these may be individually numbered inside their shells. Apparently Super Potato demonstrated this somewhere once.
Here’s a video I found of the cart at Super Potato.
Looks to be fake. The auction is using the same stock photo as an apparent fake sold on Yahoo! Japan in December 09.
