[edit] Software

See: PS2 Emulation

All consoles have hardware information. In GameOS you can call Lv2 Syscall 393 (0x189) sys_sm_get_model
to get your consoles information. In Lv1/Hypervisor its in the repository nodes sc 0x5B lv1_get_repository_node
with Parameters "sys","hw","config" usually noded as "sys.hw.config#0" or something. These information are mostly
technical related and not just apply to the software emulator, but the PS3 system as a whole.
