Hi all, this is Targhan/Arkos, the creator of Arkos Tracker.
As the tracker is still in alpha, I didn't want to spread the word about it too quickly, as I am already drowned in feature requests (and bug reports, yup

) for the CPC users

.
DBug kindly notified about this thread. I don't code in 6502 so I won't code the players by myself. I *could*, but it wouldn't be as efficient as what an experienced coder would do.
However, I have already two Z80 players ready with each their own formats (all documented): AKY and Lightweight. AKY is a very very efficient format CPU wise, yet remains quite interesting memory-wise. It is some kind of clever register dump that use the full knowledge of the song to find patterns and encode only what is necessary. As an example, a complex song of 4-5 minutes, with very few repetitions is encoded in less than 17kb. So a more simpler song could be encoded in much much less.
So I think the AKY format would be the way to go, at first. The other players are more CPU consuming, and also more complex to adapt.
Anyway, don't hesitate to ask for anything you need, I'll try to do what I can
