;; Proof Of Concept Zsound player using a binary blob version of zsound library by ZeroByte relocated to something usable here.
;; Can play ZSM (music) and ZCM (pcm samples).
; NOTE: the ZSound library is DEPRECATED and ZSMKIT is its successor.
; find prog8 examples with ZSMKIT here: https://github.com/mooinglemur/zsmkit/tree/main/p8demo
; "issues":
; - prog8 (or rather, 64tass) cannot "link" other assembly object files so we have to incbin a binary blob.
; - zsound player ZP usage is only known after compilation of zsound lib. And then this has to be blocked off in the prog8 program.

; NOTE: this is a proof of concept to stream ZCM digi from disk while playing.
; currently there's no real streaming API / circular buffer in zsound,
; so it simply loads the whole ZCM file in chunks in memory sequentially.
