Rebooting SuperCharger

[supercat]

I'm trying to make my code reboot a SuperCharger (to save having to power-cycle my machine). The following crashes. Can anyone tell why?

			ldx	 #31
rlplp:
			lda	 RLCOD,x
			sta	 $80,x
			dex
			bpl	 rlplp
			ldy	 #16
			jmp	 $80
RLCOD:
			nop	 $1F00
			nop	 $1FF8
rlcd:
			sta	 WSYNC				
			dex
			bne	 rlcd
			dey
			sty	 AUDF0
			sty	 AUDV0
			sty	 AUDF1
			sty	 AUDV1
			bne	 rlcd
			jmp	 ($1FFC)

I think $00 is the banking mode for starting up the SuperCharger, $1FFC is its hardware reset vector, and I'm waiting plenty long for the ROM to power up. What's the problem?

In what context are you calling this? Seems like all you would have to do is jump to the loader and ask for loadid #0 (as multiloaders do). Then if you load in the first load of any game it should just overwrite what was there and be equivalent to a powercycle.

I've caused the SC to restart itself with some buggy code, so it can't be difficult to do.

 

I see that bit zero of the banking mode tells the SC whether or not to power up the ROM. So you'd need to change the above to nop $F001.

 

What's with all that funky audio stuff?

Trying to track down exactly when the thing was crashing. The SC doc I had said the 'power down bit' is 1 for power down and '0' for ROM operation. But maybe that's backward.

I may have incorrect information - I'm just going from comments I found in source code.
