 +==== Colour Flashing Notewriter Style ====
 +Have you saw programs like Face Noter, Octanoter, etc. All those programs use a special extra colour mode, to activate char flashing. Some of you may find it to be really difficult to understand how it works, but it is actually *that* easy to remember. All you need to do is switch $D011 to $5b to get extra colour mode, and create a colour cycling routine. Here's a routine for it.
