Mana_Araxis: I had to refund this due to a glaring issue. Audio lacks reverb effects and songs don't loop properly compared to the PS1 version. Hopefully those get fixed. Much like what Square Enix did with FF7 on Steam; replacing the MIDI with looping PS1 OST.
Thanks to Felicity on Discord i checked the BGM Files with the provided Tool Extractor.
The PSX Version has Data there, that the Audio CPU will read and play or replay as wished, as a PC can't use the same CPU the PSX had, they seemingly used just MP3 Files.
The 75 Files called BGM have single MP3s in them that contain all the Songs that are played in a Screen/Scenario (So there is the Background, the Battle Music, the Fanfare etc. all in one MP3).
Seemingly due to Space Concerns back then, they couldn't squeeze it perfectly into the MP3.
To get rid of the Loop Problem or Reverb Effects, it would be necessary to record the Music and change the Code to the Parts where it loops better.
I guess this is the hard Part, as it need someone that can change the Code.
