This is what I did some years ago, when I ported the Spectrum128
Cybernoid1&2 players to 6502/Mockingboard:
http://www.tomcharlesworth.pwp.blueyonder.co.uk/Cybernoid.dsk
(Sorry it's a ProDOS 8 .dsk requiring a 65C02 - I will add the DOS 3.3
version)

Unfortunately it doesn't work properly on real h/w... it only works
well on emulators (AppleWin and Virtual][) - proving our emulation
isn't perfect! And I never found the time to debug it on real h/w (my
guess is I'm hitting the 6522 too fast). If you are interested in the
code for this, then let me know.
