For your consideration is one used, tested and working reproduction game. 
 
Possible Mission is the NTSC hack of Impossible Mission that fixes the bug in the original game so that it can be solved and beaten.  Please be aware that this cartridge only works on the new 7800+ and 2600+ and will NOT work on an original 7800.  Impossible Mission required extra RAM to run and was not a standard cartridge but works on emulators just fine.
  
The title of the original game is absolutely prophetic. Impossible Mission is just that: impossible. The American version of this game has one of the biggest video game programming flaws of all time. Certain needed key card pieces are placed behind terminals that are unsearchable. Therefore, you will never, ever, ever be able to unlock the door leading to the bad guy, Elivn Atombender... so you never can beat the original game!
