I found the cavas pictures but they're not redrawn, they're the old sprites (which seems unnecessary because those frames are already in the original game files, unless they had to recode it completely). They may have been going a similar route where SMI:SE started out in classic mode and then switched to SE mode for the intro. Except in MI2:SE they just keep the canvases in classic mode and everything else in SE mode? Just guessing...
