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: … 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.


Reverb or Ebay asking prices are really bad price reference, to be honest.
If you check Ebay sold listings (click advanced and check the sold box), there were two sold earlier this year
Game Boy DMG + Nanoloop 1.2 for  81€
and one with GB Pocket included for 65€
