As some of you might know, I'm one of the programmers in Super Mario Galaxy 2.5. I've done a few things for SMG2.5, but one of my main goals has always been getting Flying Mario and Ice Mario working.
Very recently, I managed to create a basic ASM hack that would make the Fire Flower transform me into Flying Mario. It completely worked, triggering Flying Mario's abilities, outfit, and music. This was an important achievement, because now I knew what function in the game's code triggered Flying Mario. I uploaded a video of this hack on Youtube.

Notes:
1. This does not work on the Wii yet. It only works on Dolphin right now. I'm currently working on a way to make the hack work on the Wii.
2. Even though it looks like I am, I'm not collecting a Red Star in the video. I'm collecting a Fire Flower, which I have hacked to make look like a Red Star.
3. If you want to play this hack, I've provided a link in the description, but I'm not going to tell you how to play it here.
It wouldn't really look profesional if we made it so that you had to use cheat codes to beat a level
