Shaking the Screen in Screen 13

You can do a nice shaking effect changing the VGA offset (some weird and obscure VGA register). This is easily done with this piece of code (by Piptol, slightly modified by na_th_an):

duration% = 25600

FOR x% = 1 TO duration%
OUT &H3D4, 8: OUT &H3D5, x%

Of course, adjust duration% to fit your needs.
