|
|
Loosely based on a BASIC program by FozzTexx
|
|
|
|
Usage:
|
|
BRUN FIREWORKS
|
|
|
|
press any key to toggle sound and restart
|
|
|
|
This code uses cycle counting extensively.
|
|
This is how HGR and 40x96 LORES are mixed.
|
|
|
|
HPLOT0 was made cycle-invariant, which was a pain.
|
|
HGLIN (allowing HPLOT TO) was intended to be too, but I ran out of interest.
