Hi Richard,
it seems to work. You may add it back to E-UAE :-)
Regards, Henk

Actually, thinking about this, what you'd probably want to do is something like:
#ifdef ADDRESS_SPACE_24BIT # define MEMORY_BANKS 256 # define MEMORY_RANGE_MASK ((1<<24)-1) #else # define MEMORY_BANKS 65536 # define MEMORY_RANGE_MASK (~0) #endif
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.
Cheers, Rich
