BTW.... the listing in C= hacking is wrong...
This is whats listed.....
MULT LDA #$00
LDY #$09
]LOOP LSR
ROR ACC
BCC MULT2
CLC
ADC AUX
MULT2 DEY
BNE ]LOOP
STA EXT
This is what it should be...
MULT LDA #$00
LDY #$09
CLC
]LOOP ROR
ROR ACC
BCC MULT2
CLC
ADC AUX
MULT2 DEY
BNE ]LOOP
STA EXT
He probably unrolls the loop in is code, and has only the first one as a LSR to avoid the CLC
