Multi Sprite Interrupt Unsave

[sage]

Has anyone some experiences using multiplication in interrups?

How to prevent unsave accesses? I am a bit afraid of chained sprites which are interrupted...

Atari says, it is no good idea, as it cannot be restarted. Also I'd say they take far to long to be used in interrupts.

 

But actually, I never tried it.

They are faster than doing it by hand, at least for 16x16

As to my understanding, the math engine is not linked to the sprite engine.

The only problem is that the multiplication cannot be "restarted".

Means, no math in foreground if you want to use it in the interrupt.

That is what is not clear to me (from the doc). I interpret it that you are not allowed to do mult and sprite in parallel. But if I can do multiplications while I interrupted the sprite engine, it is fine with me.
