Here's a Domesday (best possible quality) capture from the 1988 JP LD:

These are lossless files, so keep that in mind.
Unfortunately the audio on this LD is in mono, and the included lossless encode of the 2nd side has blown out Japanese audio. (English audio is fine)
I think it's possible to redo it using the included .ldf file, but I haven't been able to figure out the software.

Here is an encode of a regular composite video capture of the 1990 US LD:

The color grading on this LD is strange, but it does have digital stereo audio.
Personally speaking I prefer the 2007 DVD (4:3 open matte) or the 2011 BD (1.85:1) for this one, they didn't scrub it much.
