I have the EU demo if that counts for anything.
However if you're just looking to play the game out of interest, the PSN version is by the far worst port available.
The arcade version of Heritage for the Future has an active community on fightcade, otherwise I'd look into the Dreamcast version.
I own the PS1 version which is considered the worse of the two physical retail releases due to some slowdown and censorship reasons. However it's the only version with a story mode which I love.
Best of luck if you're looking for the EU PSN version for preservation reasons.
