Changes
On the Amstrad [[Plus]] range, it couldn't be used as well. But some possibilities exist.
It allows to "Multiplex " the same Sprite at different rasters lines.
The technic impose some specifications :
* The same Sprite is simply copied /duplicated as it is.
* No multiplexed sprites can be at the same Line.
This can then be used for games like Shoot'emups... as the spriutes sprites don't always need to be well animated (just moved) and as enemies waves are often pre-determined (R-Type is the typical exemple).
So it fit well for Vertical Waves of enemies.
