There was an old thread in this forum about the Universe Laser Heisei releases, but now it quite literally seems to have disappeared. I looked through the forum pages and tried searching for it, but couldn't find anything.
Some peeps did post screen caps in that thread though. From what I remember,
G84 was non-anamorphic with iffy picture,
Biollante was anamorphic with R2-quality picture but with the addition of a lot of digital artifacting (much like Madman's R4 discs, I doubt this artifacting would be noticable on a TV, just on the computer).
GvsKG was non-anamorphic with very sub-par picture, and
GvsM was just like
Biollante. And though nobody posted any screencaps of these last three, I know that
GvsMG2 and
Destroyer are both anamorphic while
Spacegodzilla isn't.
I remember somebody did post subtitle screen caps from the
Biollante disc, and it was very Engrishified from what I could tell. Maybe those were just some bad instances, but if they're representative of the whole movie's subtitles (or the rest of Universe Laser's titles for that matter), I'd say they're not worth having. But then again, they are pretty damn cheap...
I don't own any of them myself, but my advice to you is to just buy all five of the Madman R4 Heisei releases (
KG through
Destroyer), and if you must have a legit, subtitled release of
Biollante on DVD, well, the cheap R3 is the only one of that kind in the world. There are alternative means, of course. . . But just skip the R3
G84 altogether.
