Yay, for some reason it was enough to add a "hiku=(filename)" line into the preset definition - hiku still doesn't have an ID, but the song plays XD
So I guess the IDs are just there to make them selectable in FF7music, right?
Well, all's fine now ^_^ Say.. just a theoretical question, but is it actually possible to make a gapless looping option, using some kind of buffer or whatever to loop without pause? PSFs don't work for me, so I'm still using the OST - but if there was such a loop option, I just may edit out the fade-outs and make them loopable.
