-To turn this into a physical address in the cartridge ROM's space, you should use the following equation: ''%%((addr & 0xFFFF) | ((addr & 0x7FF00000) >> 16)) & rom_mask%%''.+To turn this into a physical address in the cartridge ROM's space, you should use the following equation: ''%%((addr & 0xFFFF) | ((addr & 0x7FF00000) >> 4)) & rom_mask%%''.
  
 The high four bits of the CPU address are ignored for physical ROM address transformations. This is because their purpose is to tell the compiler/linker at what address the CPU accesses the 64KB bank, not where it is physically stored on the cartridge.
