The default mappings have one Block Address Translation (BAT) that translates to all of physical memory. Most games use the GameCube/Wii's default BAT mappings, and as long as they don't try to access memory outside of that, all that has to be done is making sure accesses end up in the right place.

Theory 1: The Software Only Writes to Valid Memory В¶ДЄs long as the games only write to valid memory, Dolphin doesn't have much work to do. Secondly, the GameCube only has 24MB (and some specialized areas) of RAM across a 4GB address space, meaning most memory addresses have no RAM backing them! If a game were to access a real memory address with no backing memory, it'd get garbage or even crash! By using virtual memory, the MMU can throw an exception giving the game a way to handle the situation or provide valuable feedback to developers on what went wrong.Дolphin is able to emulate the MMU with several degrees of accuracy based on theories of how the game is going to behave. First of all, it gives the CPU an opportunity to cache accesses, greatly speeding up the efficiency of accessing often used values. The games are given access to virtual memory instead of real memory for several reasons. This can be done in two ways, with Block Address Translations (BATs) for huge portions of memory or the page tables for small fine-grained mappings.

Rather than directly accessing available RAM, games interface with virtual memory which is then translated to physical memory by the MMU. The Memory Management Unit, or MMU, is responsible for quickly giving games access to data and code.
