Seems 7445/7450 emulation is incomplete, if you want to run the 7447a in TCG mode you’ll have to patch it to point to a working CPU.

IE:

    POWERPC_DEF("7447a_v1.0",    CPU_POWERPC_74x7A_v10,              7445,
                "PowerPC 7447A v1.0 (G4)")
    POWERPC_DEF("7457a_v1.0",    CPU_POWERPC_74x7A_v10,              7455,
                "PowerPC 7457A v1.0 (G4)")
    POWERPC_DEF("7447a_v1.1",    CPU_POWERPC_74x7A_v11,              7445,
                "PowerPC 7447A v1.1 (G4)")
    POWERPC_DEF("7457a_v1.1",    CPU_POWERPC_74x7A_v11,              7455,
                "PowerPC 7457A v1.1 (G4)")
    POWERPC_DEF("7447a_v1.2",    CPU_POWERPC_74x7A_v12,              7445,
                "PowerPC 7447A v1.2 (G4)")
    POWERPC_DEF("7447a_v1.5",    CPU_POWERPC_74x7A_v15,              7445,
                "PowerPC 7447A v1.5 (G4)")
    POWERPC_DEF("7457a_v1.2",    CPU_POWERPC_74x7A_v12,              7455,
                "PowerPC 7457A v1.2 (G4)”)
TO:


    POWERPC_DEF("7447a_v1.0",    CPU_POWERPC_74x7A_v10,              7410,
