Great!Well, thanks to @AD and @EmuMusicFan's help above, here's the first batch of remaster/comparison clips lifted directly from the PSX discs
Annoyingly, AVISynth threw a fit trying to read the uncompressed AVIs from HCl's conversion application. I managed to re-encode them as h.264 MP4 files with (I'm confident) no loss of detail though, and then I was off and running.
What about the ending part (sc_178a)? The biggest problem with the PSX version is actually the distortion caused by over-compression, which I guess is basically a result of the high JPEG compression ratio kind. The detail of the picture seems overly cluttered and dirty. Other than that, the PSX version is technically the best.
