Some Really Magic Numbers in VGA Demo

TJHJ · 2009-05-17 02:39

This is from the VGA_Demo.spin file in the examples folder of the prop tool.
·
Ok So I was trying to figure out how the button depress is effect is being created.
·
This is the part of the file causing it.

 
 
'This is after the "buttons" have been drawn.
 repeat
    i := cnt
    waitcnt(i += 22500000)
    spcl := $30101020
    waitcnt(i += 22500000)
    spcl := $10301020  

 
Dat Part associated with special.
 
spcl                    long    $30100020       'greenbox
                        long    $3C142828       'cyanbox
                        long    $FC54A8A8       'greybox
                        long    $3C14FF28       'cyanbox+underscore
                        long    0
