THIS GAME WILL HAVE A POWER UPS GLTICH, THAT  MEANS THAT THE POWER UPS THAT WILL APPEAR AFTER HITTING A BOX , SOMETIME WONT BE THE ONE YOU NEED FOR THAT SPECIFIC LEVEL, YOU WILL HAVE TO EXIT THE LEVEL AND FIND THE POWER UPS ELSEWHERE THEN COME BACK TO THE CURRENT LEVEL.
ITS MORE CHALLENGING BUT THATS HOW IT IS.

Brand new game.
Works perfectly !
This is only guaranteed to work on original system, should work on 90% of clone consoles BUT I DO NOT guarantee functionality on none of them. I know for sure it will NOT work on a RETRO FREAK and RETRON 5.
