Some Glitch Explainations

Barrel Storage - Frame Perfect Trick. break the barrel but hop on it while you still have the action command. If you time it right, you clear Luigi's action command which leads into even more glitches. (Sign Glitch)

Sign Glitch - Using the sign, when you have a cleared action command, you can essentially cycle through all the action commands through the game until you get the one you want. In this case we combine this to get fire hand on Mario (even though you cant see it). When you have fire hand, you can separate small Mario and Luigi  and do a precise jump in order to finish with High Jump on Mario.

High Jump (Action Command Glitch) on Mario - This is what all the glitching was for. We did it in order to get high jump on Mario which essentially breaks the game. Basically you know how by we used sign glitch to change action commands. This gives us the power to do that anywhere and it gives us the ability to get glitched action commands as well which have crazy properties from normal.

Rock Skip - Using High Jump on Mario we change around glitch action commands. When i do the right sequence of commands, I am able to alter my height on the y axis of the game. This lets me just walk over these rocks.

Flying Hat (Trunkle Skip) - Using glitched Hammer command, I put Luigi in the ground. When hes in that form, Hat Luigi has weird properties. HE gets really clippy and like to warp around everywhere. But if I get in the right position, I can choose where to warp like passed the boss and go straight to the exit. I can take Luigi out of the ground through the action command glitch.

Red Pepper Glitch - Mario eats a red pepper. It increases his attack for a short time but, it also gives him the heavy status. If Mario dies however while the effects are on. He can be revived and keep the attack power for the whole fight without being weighed down.
