ROM Hack New Super Mario Bros

[Marc1994]

Can someone hack New Super Mario Bros DS?
I want the feather suite, and Yoshi in the game...

Or only the feather suite...
Can someone try it? Or give me hints to do this?
I think the Super Mushroom could be replaced by Yoshi.
And the feather suite by Mini Mushroom...

Could someone try it?

unfortunately, powerups are hard coded into the game
to change what they do, you would need to read/write ASM code

aaaand not many people can do that  

but if you still need help, try jul's NSMB hacking section
