Well, one first thing is, that the source doesn't
compile. Seems like there's numerous equates missing
somewhere:
MBOL LIST: (Unresolved symbols only)
PF_Score ????(r )
VS_Enable ????(r )
VB_Enable ????(r )
lt ????(r )
gt ????(r )
PF_Reflect ????(r )
VB_DumpPots ????(r )
P_ThreeClose ????(r )
P_TwoClose ????(r )
J0_Right ????(r )
As for suggestions:
- Pack this into a subroutine:
WaitTimer
lda INTIM
bne WaitVBlank
rts
Since you're waiting for the timer 11 times, this'd save
you already ~20 bytes.
I'm not sure why you wait that often for something,
normally you'd only wait for the overscan and for vblank
to finish, BTW.
- On one location you do
lda #9 ; 8 lines
sta INTIM
-> You can safely remove this :-)
- Replace
lda SWCHB
and #$01
cmp #$01
beq CheckStages
with
lda SWCHB
lsr
bcs CheckStages
- remove all
jmp EndCase
In your switch/case implementation.
- Try using a different random number generator. (Sorry
Erik :-))
More later. It'd help if you'd provide a compilable
source...

Manuel
