Another action replay hacking device related thing, but pure evidence of the lazy guys at nintendo. Use the 'change into yoshi while loading with R+L+up' code. Then, switch to yoshi while the big boo's haunt level is loading (you can't beat the big boo that guards the entrance with yoshi) and you'll see the yoshi picture in star selection. Then, as yoshi, go in the luigi painting. As yoshi, face big boo (and this is the best bit.) and what does the ghost say? Ha, a bald guy? No, nothing!! Stupidly stupid.

PS. enter this with any character with the code moon jump to go out where you fell in the room from, travel over to the mirror side, then fall back down, to go in the mirror. Hacking mario 64 Ds is funny!
