Yeah, maybe it's a little off (I did suspected this earlier but wasn't so sure because I never saw the preopening on the PSX). Adding a 2-3 seconds delay to the midi should fix that, but is there a delay before the preopening start on the PSX, right after the Squaresoft logo?
And I'll need to know when, in the song, exactly does the FF logo appear?
Is it supposed to start appearing when the first of the four last notes is playing?
BTW, what was making the chocobo midi not playing?
