Hello!
I owned Nanoloop 1.2 for gameboy about 20 years ago but lost it. A friend of mine has the 1.2 in the traditional greg gameboy cartridge. He says he'll sell it to me for $250 and references this post as the fair market price: https://reverb.com/item/37295290-nanolo … meboy-rare
Does this price seem high or fair market value? Is there a difference between the grey cartridge and these semi-transparent ones?
Any insight is greatly appreciated, as I cannot seem to find much info on pricing and market.
