Is there a time limit when to change from boot disk to backup ?

OrigaChip. I don't see whay that chip shold be different in this respect from NEO. Maybe I'm wrong in my thinking, Dust2Dust - but I rather thought that the modchip had done it's bit by the time that Memory Manager 16 gets hold of things.

Still, we should hear a bit ore from Tingle especially detail of what goes wrong and what he thinks the time limit might be.
