Hi there!
LDA #212
STA xdelay
LDA xpos
CLC
ADC #02
SEC
DivideBy3
DEC xdelay
SBC #$03
BCS DivideBy3
This version is MUCH slower and can eat up a whole extra scanline
depending on the value of xpos.
Way cool, I might even switch to this, as the main reason for coding this
formula was ROM shortage :-)
(the code saved me a 150 bytes lookup table...)
Very handy if you need to burn up those pesky, unwanted free cycles.
Funny thing is, I was very concerned about the cycles this would eat up,
especially when it was possibly called 4 times per frame with xpos values
up to 140.
That was when I discovered to my own surprise that Seawolf didn't use any
Overscan time at all so far... ;-)
Greetings,
Manuel
