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. It also has the highest PS2 peripheral support.

* 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 EE is rendered via Software, which has a little reduced compatibility, which can lead to graphic artifacts in some games. PS2 peripheral support is also reduced. 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. There is no PS2 peripheral support.

Playing PS2 Classics on a console with PS2 hardware will '''always''' override the PS2 hardware emulator, irrespective of whether it is jailbroken or not. Therefore it is not recommended to play PS2 Classics on these consoles as it puts unnecessary load on the Cell and/or RSX, unless the title does not work with the PS2 hardware emulator.

On jailbroken consoles with PS2 hardware, it is possible to override the hardware emulator to use the PS2 Classics emulator instead. This is noteworthy because the PS2 Classics emulator can perform better than PS2 hardware emulation for some titles. For example, the game ''Battle Stadium D.O.N'' is unplayable on either PS2 hardware emulator, but is playable via PS2 Classics. Also, on a jailbroken console, the PS2 Classics emulator can be set up to use custom configs, many of which allow more games to be playable.

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.

Early PS3 FAT [[CECHAxx]]/[[COK-00x#COK-001|COK-001]] and [[CECHBxx]]/[[COK-00x#COK-001|COK-001]] : Full compatibility with GS+EE and Rambus memory. Later [[CECHCxx]]/[[COK-00x#COK-002|COK-002]] and [[CECHExx]]/[[COK-00x#COK-002W|COK-002W]] had instead of EE+GS a single GS and lacked the Rambus memory.

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

Result examples:

XMB checks this flag and if == 0, it will give following message: "This model of the PS3™ system is not compatible with PlayStation®2 format software."
