@alyx@witches.town @Felthry Yep! A few differences.
* The PS1 version has a different instrument set (sometimes better, sometimes not) and simplified effects like reverb. Some songs sound wrong as a result.
* The Saturn version has some extra graphical effects that were simplified or removed for the PS1 version.
* The second Saturn version uses MPEG cutscenes.
* All FMVs in both Saturn versions run at 24FPS; some FMVs in the PS1 version were cut down to 12FPS to reduce filesize.
