• Implemented no-hack Z3 memory mapping, lets OS handle Z3 autoconfig without patching base addressess from >=0x40000000 to >=0x10000000. This mode is not JIT Direct compatible. Option in Memory panel. Do not enable unless you know what are you doing and you really need 100% matching real hardware Z3 address mapping.
• Use no-hack Z3 allocation automatically if all configured boards fit in official Z3 space, fully JIT Direct compatible. Requires 64-bit Windows and available space will be about 300M to 500M. RAM panel text string shows free space. 32-bit Chip RAM does not count, it is not Z3 board and it is always located at 0x10000000.
