I posted about a Virus (early Dr. Mario) prototype way back in 2010.
Now, three have popped up on eBay.
From the seller:
This auction is for three (3) different first-party NTSC prototype versions of what would later become the game Dr. Mario for the NES. Each one of these unique cartridges represents a different phase in the development of this title.
Virus (1989): Found at a flee market in San Antonio, TX, in 2010 and then sold to me. This is the earliest known prototype version of Dr. Mario, or Virus if you will.
Virus (1990): Found by a guy in California in mid 2008 while helping his friend to move. In July, 2008, it was sold to a Norwegian collector who then sold it to me. This build is from February 2, 1990.
Dr. Mario (1990): I bought this cartridge directly from a source in 2008. It was used to take screenshots for the Nintendo Power magazine.
