Here's the opening for Tales of Phantasia PSX version which I did play that several years ago. Enjoy.
PS - Also to note that the SNES opening did also have the vocal song, in which it's quite an accomplishment seeing that back at 1995 it widely accepted that it would be impossible to add vocal song into the cartridge. As for PSX opening here, you can say that it's should be iconic because it's the localized PSX JRPG (Unofficial though) with Japanese vocal song, which is a big deal more than it sounds because back then many localized JRPG for PS1 did cut the vocal and change it to instrumental - Tales series were the one who suffer from that policy.
