Kizyr, you won't find any differences between the Japanese physical PS1 release and the Japanese digital PSN PS1 release, because it is simply the same game discs converted into downloadable files.
In fact, Sony doesn't even allow changes to be made to these games, because they MUST be 100% the same experience as the original PS1 release.
The only thing you MIGHT ever notice with PS1-PSN releases, is that they might have slowdown when the game (any PS1 game) reaches a certain sensitive part in the code that is a bit difficult to handle or emulate on whatever modern hardware you use (PSP, PS3, PS Vita).
And maybe slightly faster loading times due to it being digital, but it's very minimum.
With Lunar 2's Japanese PSN release, the differences are the same as Saturn to PS1,
and USA PS1 - JAP PS1.
I think I found something else, but I'm not a 100 percent sure. Screenshots!
Hmmm... That's weird! As in, REALLY FREAKING WEIRD. Why would Working Designs' version have that change that at ALL??
If they're going to change it, it should be for the better, not worse! Here's a gif, but I am going to get to that part myself and take a screenshot from inside the system to have an accurate picture comparison, just dont know when.http://postimg.org/image/6v7bnaclf/
Something to note in anatomy, and this is really basic, the distance between your eyes should be the same as your eye's width.
How these artists forget that, is beyond me. I'm far from a professional artist, and I know this, so why don't they? Ughhhh.
In the Sega CD version, it was correct. http://lunar-net.com/eb/screens/1/image ... UE_623.jpg
Anyway, out of the 2 PS1 versions, the Japanese version's face is better.
