Thanks meynaf.

Yep, code mask out the bit unused in real DDF registers (like for FMODE).
So no 0000-00ff range :)
This made the proposed solutions much more interesting.


Exaggerated!

What really bugger me in my version is the explicit mask declaration for 'chipset'.

Wait, this is not the proper way.
FMODE lower two bits should always work, like the 'real' FMODE.

So a value = $8007 is valid and set 'fetch' or that which is =2.
