PS2 Compatibility
If you are looking for the list of PS2 games compatible with non backward-compatible PS3's, see the PS2 Classics Emulator Compatibility List.
PS2-Compatibility
PS2 emulation on PS3, occurs in 3 different ways:
- In consoles with EE + GS + Rambus, emulation has the highest compatibility of all, running PS2 games at the hardware level. In these consoles, the emulation runs directly on the dedicated hardware, reducing the CPU and GPU consumption of the PS3 hardware.
- In GS-only (No EE and Rambus) consoles, PS2 emulation is shared between the PS3 hardware, since the EE processor is omitted, delivering the entire processing load to the Cell. In these consoles, the GS is rendered via Software, which has a little reduced compatibility, which can lead to graphic artifacts in some games. When titles do play fine on one of these consoles, smoothing of PS2 games seems to be slightly better compared with EE + GS + Rambus consoles.
- In consoles without EE and GS, the emulation of PS2 occurs through the "PS2 Classics" package, where the emulation occurs entirely via software, sharing the processing of EE emulation with the PPE cores and the 7 SPE cores. Software emulation has less compatibility between the 3 modes, as it depends on emulating all the components of a real PS2 in a fully virtualized environment. On jailbroken consoles, it is possible to override the corresponding PS2 hardware emulator to use "PS2 Classics".
Supported via Hardware (EE + GS or GS only) consoles allow the execution of PS2 games via physical media (CD / DVD ROM), including PS2 Classics (hardware) emulation. Consoles with no hardware compatibility can not play PS2 games from physical media, however with jailbroken consoles it is possible to read a PS2 game disc to create a playable copy.

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.
