Alright so once you have all the Blueprints and you talk to Snide he'll let you play mini-games like from the barrels you'd jump inside. So when you click on any of the mini-games you quickly press the Z button, the B button, and the A button all at once. You'll know when you have done the glitch because you'll start off in front of Donkey Kong on a platform with black nothingness around you and no music. Donkey Kong blinks but does not move and you can walk through him. There's a yellow balloon there that if you're Donkey Kong you can shoot and get 10 bananas. There are 4 square pillars you can get on. When you walk off into the black nothingness you'll start over where you began. The only way to get out of the glitch is to restart the system or turn it off and it will not harm your game or system so no worries. Enjoy.
