Contents

This is main routine of sound driver.
This function will play the BGM and SE.

Notes

  • User application SHOULD call this function nsd_main() every flame or 1/60 sec.

    • Usually, this function are called from V-Blank (NMI) interrupt.
    • However; MUSTNOT written directly the pointer of this function nsd_main() to interrupt vector of 6502. (This function nsd_main() does not keep each register (A X Y).)

  • If the bgm and se data is in another bank outside real memory area, User MUST allocate the bgm and se data to the real memory area with the bank change before call this function.
