→AOT NRO
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.

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.
* "GET_FUNCTION_INFO": Ptr to a table, where each entry is 0x18-bytes. Structure: +0x0 = ppc_code_addr, +0x8 = nro_code_addr, +0x10 = string ptr (normally "").
* "GET_FUNCTION_INFO_SIZE" Ptr to the size of the FUNCTION_INFO table, in entries.
* ...
Each func in the NRO listed in the above table (which are the AOT funcs) is called with x0={state ptr}, where state contains:
* +0x0: u32 array for the PPC GPRs.
