I have a .cbr file of an issue of Nintendo Power from 1993 (I'm not sure of the exact issue, so it may take a little while), but there's a three or four page article on the making of the film, as well as a few shots from the set, including Samantha Mathis looking on while John Leguizamo plays Super Mario World. If you want it, I can put it up on Rapidshare for you.
