ok, so maybe the next step would be to use the value true or false of 
--addr24 in STRAM_ADDR or similar macro instead of always truncating the 
higher 8 bits of an address.
This way, we get a behaviour closer to either a falcon with limited 24 
bit addressing or to a TT with full 32 bit addressing capability or  (or 
to a falcon with a CT2 extension board if we want to simulate that somehow)

I might look at this once I finish to update Winuae's core.
