That's definitely a good sign. Based on what I've read, it seems like this game is a hacker's worst nightmare. It's been in development as far back as 1999, but almost everybody who has touched it seems to have disappeared. It's a shame, because TMZ is one of the last great SNES RPGs that hasn't been translated.
How? Even before the chip was fully emulated (and the decompression format known), pre-made graphical memory dump packs were already circulating online and since they were uncompressed, and the text in the font was uncompressed. Besides the credits, it could have been handled even using the rudimentary methods from back then (though text volume would be the one problem).
It's definitely a case of bad luck, much like Arabian Nights, Traverse, and Dragon Quest 3. Where the consecutive teams would disband before anything is done.
Hacker's worst nightmares would be rather the whole Tokimeki Memorial series, Ys 5, Earthbound, or maybe the Oni SFC game using vertical text.
