Hi Richard,

it seems to work. You may add it back to E-UAE :-)

Actually, thinking about this, what you'd probably want to do is something like:

# define MEMORY_BANKS  256
# define MEMORY_RANGE_MASK ((1<<24)-1)
# define MEMORY_BANKS  65536
# define MEMORY_RANGE_MASK (~0)

And then have the access functions as:

STATIC_INLINE uae_u32 get_long(uaecptr addr)
    return longget_1(addr & MEMORY_RANGE_MASK);

etc. etc.

Basically, you want the top 8 bits of an address to be don't cares on the 68000.

I thought there was something like this tucked away in the code somewhere already, but some parts of uae are such a rabbit warren it's hard to find your way aroudn sometimes. Maybe this got lost somewhere along the line.
