80s Trivia: What was the name of the Nintendo product that allowed you to enter cheat codes for any game?

Video games can be frustrating.  Really frustrating.  I'll never forget the time that, disputing the call made against my attempt to steal 2nd base in Super Bases Loaded 2, I threw the cartridge clear across the room (in my defense, I think I was nine).  Anyway, they sometimes seemed designed to be impossible, thus making you play again and again - this is particularly prevalent in arcade games.

For video games, this could be really problematic - you get three or four levels into a game, no sweat, but then BAM, you get stuck on one section and can never break through.  Fortunately for kids like me, Nintendo developed a product that allowed you to enter cheat-codes into a game that came with a specified cheat (infinite weapons, lives, continues, etc).  So, off of Pocket Trivia: 80s Trivia - What was the name of the Nintendo product that allowed you to enter cheat codes for any game?   Was it:

• Game Destroyer
• Game Shark
• Game Wizard
• Game Genie

80s Trivia: When it was first being developed, Super Mario Brothers 2 was known as what game?

TI'm in an 80s sort of mood today, so let's keep up that trend by reviewing another question from Pocket Games: 80s Trivia.

As a kid in the 80s, I grew up obsessed with Nintendo.  The Super Mario Brothers were always one of my favorites - particularly Super Mario 3.  But, that being said, its Super Mario Brothers 2 that is the subject of today's question - particularly given  its weird nature.  After all, Super Mario Brothers 2 is totally different than any other Super Mario game, featuring worlds and villains never before seen (and never seen again).  Why?  Because it was originally a totally different game.  The real Super Mario Brothers 2 was released in Japan - but it was deemed as "too hard" for an American audience.  So, what happened?

The answer: another game was actually hijacked and turned into Super Mario Brothers 2.  What was that game?    Was it East Your Veggies, The Adventures of Luigi, Princess' Hour of Need or Yume Kojo: Doki Doki Panic?
