* The Player 6.1A for Devpac 3 (and later ;) *
* NEEDS:
* Default sizes must be words (ASM-One default...)
* Preferably no optimizations on (the jump table must be word jumps)
* Tested with Devpac 3.04

fade = 1 ;0 = Normal, NO master volume control possible
;1 = Use master volume (P61_Master)
jump = 1 ;0 = do NOT include position jump code (P61_SetPosition)

;1 = friendly
CIA = 1 ;0 = CIA disabled
;1 = CIA enabled
exec = 1 ;0 = ExecBase destroyed
;1 = ExecBase valid
lev6 = 1 ;0 = NonLev6
;1 = Lev6 used
opt020 = 0 ;0 = MC680x0 code
;1 = MC68020+ or better
