ROM Hack Zelda demo Slide Show

[Gagarin]

I just got the demo of Twilight Princess as a demo. It is just sumple 16 pictures and music.
So I'm thinking. Maybe hacking the rom and injecting custom pics and music?
We could make for example "Zelda Slide show" or "Spirit tracks" demo.
We have screens on games websites.
The problem would be with that flute music from trailer

Any way, what do you think guys.
