I had this game ages ago; it's noteworthy in that it's the version of the game that most of the modern-era re-releases have been built on top of. The most obvious evidence is in the fact that when you exit a random battle, the overworld music for wherever you are restarts from the beginning of the track instead of picking up from where it was interrupted when the battle started, like it would on the PS1 version of the game. This is because the music for the original PC version were MIDI tracks, and the modern updated releases have just replaced those files with the same music files from the PS1 game without re-writing the code for how those tracks are handled by the game.
......
...anyway, here's
Wonderwall what the box looked like. I'd do some Google-fu but I'm currently on my break at work so I don't have the time. But good luck.
