As the story goes the NES 101 (top loader) was made way after the game genie was invented. And as a either design over sight or with purposeful miscalculation (Nintendo didn't really like the game genie). A game genie will NOT fit into the top loading NES.
Now this was realized this and sold a adapter to use the game genie , it was free if you asked for it, now they are very very rare.
And one is now being sold on ebay for more then a hundred dollars.
And i am not going to pay that much to mess around with some Nintendo games. So i for a way to hack the game genie to fit into the top loading Nintendo Entertainment System.
Step 2: Step Two: HACK THE GENIE!!!!
OK your done this will now fit into a Top Loading NES, just press it into the NES with a little force and it will pop into place. I also cut off the black plastic straps that are useless with the top loading NES.
!!!!!!!!!!!!!!!!!!!WARNING WARNING WARNING!!!!!!!!!!!!
ONCE YOU INSERT THE HACKED GAME GENIE INTO THE TOP LOADING NES IT WILL NOT COME BACK OUT!!
To get it out you have to case the case of the top loader off and pull it out with the top of the systems case.
Trust me you think your goign to be able to pull it back out but man its in there.
