doh, it does appear to be my particular brand of bad coding.

On the VMU bit 4 of the VSEL is SET at reset and on the emulator it is
cleared.
(bit 4 of the VSEL sets the auto increment option for the work RAM
pointer)

Problem being that I spent all week ripping my code apart to find this.

Of cource you should manualy set the bit regardless, but just incase
you are having a simular strange problem with code working on the
emulator but not on the unit itself, check when you use the work RAM
and if you explictly set/cleared the bit.
