I have now fixed Battle Mania Daiginjou track 15 - Navigators. It turns out that track not only had an error upon looping, but actually the track seems to play twice before finally looping (if you solo the PSG, it becomes very obvious), so now it's fully corrected.
I also had a look at Devilish's track Time's Running Out! I was logging this from the start with fast forward enabled, but for some reason, it slowly dropped back down to the default speed until it got to around the 20 minute mark, which was also the time I thought it would re-loop, but once it got to just around 20 minutes, it started to 'glitch' and begin to play very random notes.
Well, in the end, I actually ended up waiting for that track to re-loop for about 3 hours, but it seemed to stay in that glitched state since the 20 minute mark with no signs of wrapping back to the start like Battle Garegga does. For the time being, I think it's probably impossible for a proper rip of that track, so I'm going to leave it alone.
Anyway, here is the Battle Mania track, and for all that originally downloaded the Thunder Force IV track in the previous post, don't forget to re-download it.
