NMIDIGI_Off temporarily disables the player, NMIDIGI_On enables it again.

Similar to the Magazines section this section of the wiki consists of material which has once been released as wholes, not intended to be modified. This should be respected, and corrections/comments and so on should rather be put ouside the texts than inside.

General VIC programming is not available on this page. Instead it is devoted to coding specific demo effects and tutorials on how to make demos specifically (rather than coding in general). General drawing, non-specific to demo coding, is also on the general VIC page instead.

For multiplying by a power of two, you can use ASL multiple times on a number. For multiplying by other things, you can use two copies of the number, ASL both copies different amounts, and then add the results together. For example, here's some code for multiplying the accumulator by ten: Undisclosed base Wed, 30 Jun 2010 18:26:27 +0000
