File Write During A Demo

So, I want to be able to write a small file out in the middle of my demo ... ideally without interrupting the IRQ music and other stuff that's playing.

When I try to do that, though, the file ends up corrupt.

Is there a good way to do this..?

I'm of course using the Kernal functions FFBA, FFBD, FFD8. And then FFD5 to try to load back.

Loading seems fine - but saving is corrupt..

If all else fails I guess i need to fade the music down and pause interrupts............

Quoting Krill

But, pray tell, why do you need to write data to disk in the middle of a demo? :)

Sounds like a demo copy protection scheme to me ;)
