The AOT NRO does all main-memory accesses by accessing {global ptr set by SetGekkoMemoryPointer}+{ppc_addr}. Therefore, above base+0 == ppc_addr 0x0. Since svcMapPhysicalMemory is used above, attempting to access any PPC-addrs not in the allocated regions above will result in the emulator crashing due to accessing unmapped memory - accessing non-PPC emulator data with invalid PPC-addrs is not possible. These crashes may happen when attempting to run a different .dol with the emulator as previously mentioned. | The AOT NRO does all main-memory accesses by accessing {global ptr set by SetGekkoMemoryPointer}+{ppc_addr}.

GetStatifierInfo takes an input string param and an output u64* param. This returns a bool: 0 = error, 1 = success. The NRO compares the input string with various strings to determine an array index, returning 0 if there's no match. Otherwise, the u64 data from the located array entry is copied to the output u64. | |||
