Probably not, at least not on a "standard" Amiga with a 68000. The whole reason for "Shadow RAM" is to allow ROM code to be executed without requiring wait states to be inserted for memory accesses to system code, ROM typically being slower than RAM. But the standard Amiga ROM is fast enough that no wait states are needed. A fast 68020 or 68030 would need wait states, but I understand (not being able to afford such a beast myself) that there are provisions for "Shadow RAM" type things in fast systems already. -- Mike Farren farren@well.sf.ca.usa
