(Follow-ups to debian-legal, please.)
FWIW, I would not touch SNEeSe or any fragment derived from it with a
ten-foot pole unless they can tell you where sneese.dat came from and
what's in it. My guess is that it is an infringing copy of the
contents of an SNES64 ROM and that the history of its inclusion on
SNEeSe taints the legality of the whole code base ("fruits of the
crime" and all that). IANAL, TINLA.
