https://www.psdevwiki.com/ps3/PS2_Emulation#Description
Emulation of Playstation 2 is currently handled by 3 kind of emulators. CECH-A/B models use ps2_emu.self able to use built-in PS2 hardware (EE/GS/Rambus memory), and have best compatibility. CECH-C/E use ps2_gxemu, this emulator use physical Graphic Synthesizer found in this ps3 model, but Emotion Engine is fully emulated here, also there is no Rambus memory. All other models emulate PS2 thru fully software based ps2_netemu used for ps2 classics, and hacked now to use decrypted ISO files. Earlier before Sony provided ps2 classics on PS Store there was another soft only emulator strongly based on ps2_gxemu. It was called ps2_softemu, and had support for original PS2 CDVD. Only emulator not able to run physical discs is ps2_netemu.

REBUG TOOLBOX 2.03.02 MULTI 16: (PS2 Emu swapper’s removed as this became obsolete since Cobra 8.1)
PlayStation 2 on NON-BC Consoles
Software (SW
) Emulation:Support for
PS2 ISOs in
non BC consoles was removed in Cobra 4.30
(usb
), due tops2_softemu missing. It has been re-enabled now by hacking of ps2_netemu. You can use it in the same way as before, just load an ISO and launch from disc icon, Cobra core takes care of rest. No need for encrypted isos, isos patched with limg sectors, etc. Just your normal PS2 isos dumped from discs. However, there is NO SUPPORT for Optical Discs in PS2_NETEMU.
Note 1: Don’t forget to set the memory cards in XMB, in the old memory card utility for PS/PS2, as ps2_netemu won’t let you assign them in game. As long as you use the new ps2 launcher.
Note 2: Decrypted Config can now be used , place the CONFIG file in the same game path. An example below :
dev_hdd0/PS2ISO/God of WAR2.ISO
dev_hdd0/PS2ISO/God of WAR2.ISO.CONFIG
Decrypted CONFIG files are available via:

PlayStation 2 on BC and Semi-BC ConsolesHardware (HW
) Emulation:
PS3 Models: CECHA, CECHB, CECHC and CECHE Backwards Compatible (BC) Consoles will still use their respetive emulators
(ps2_emu, ps2_gxemu
), which have much better compatibility and also support optical discs, original or backup.
