The only strange thing I notice when comparing with 0.6.11 loaders, they don't have distorsion (they used no IRQ and dma TMU2 for cdda if I remember well) maybe it deserves a try to add the loop function to them ? Maybe the distorsion is simply not present in the first loop ?

Hmm maybe you just use mono sound for DC? Because the main issue for distortions it's a PAN changing for channels every time by game code. I can even more reduce distortions as you get in old loaders, but the PAN for both stereo channels will be on Right channel in this games. But will plays smooth.
So in mono mode distortions can be much less. It's not lost for Left channel, AICA mixed both to one Right channel. Maybe I should add setting for it, seems it can be usefull if I'm not wrong in main idea.

Maybe it will be the good one for 0.8 loader too in order to add the loop function.

CDDA there works up to end of track and in old loaders I think. I tried DMA+DMA, DMA+SQ, PIO+SQ, PIO+DMA it's not help.

I test Super Runabout, it's boot and CDDA playing perfect (also music so cool), but it's freeze on mission loading. Very disappointing. I still need fix WinCE games.

Too many, it's impossible to get back because it also uses oldest compiler versions.
Just so you know, with version 12 of GCC (and each version reduced size of binary), the size of the Extended loader (IRQ+CDDA, without additional features, it's a default CDDA loader) ran into a limit 32KB (with params and offsets), less than 50 bytes remained. In next time I should remove something before add new one to this loader type. Or add to the Full loader only.

That's right, it's just a happy, random coincidence, like the work of WinCE in 0.6.0 in general. Because it's totally wrong emulates syscalls, so bad that it worked in an unexpected way and I can't reproduce it with GCC 12, I tried.
