Stack-Up is the second entry in the two-game Robot Series (designed to be used with R.O.B., the first being Gyromite). While Gyromite could be bought by itself or in the NES Deluxe Set, Stack-Up was only ever sold by itself, which makes complete copies quite rare.

Bizarrely, like Gyromite, most Stack-Up cartridges merely contained a copy of the Famicom's Robot Block with an adapter so it could work on the NES.

Hidden Text

Present at 0x10 is what appears to be not only a build date, but a very special day:

 Programed by   
  6/24 is       
    my birthday.
  ROBOT 1       

Another message at 0x7FB0, which also appears in Gyromite, seems to be the build date of the sound engine:

  5/5 1985
