144w ago - Today PlayStation 3 developers mysis and eussNL on the Wiki have posted a method to get the PlayStation 2 (PS2) Software Emulator working on 3.55 CFW without a DRM-infected Cobra USB dongle for all PS3 Fat and Slim consoles.

Download: PlayStation 2 (PS2) Software Emulator Files for PS3 3.55 CFW / PlayStation 2 (PS2) Software Emulator Files for PS3 3.55 CFW (SRC)

To quote: Getting PlayStation 2 Software Emulator working

Method (on Firmware 3.55, without! Cobra-USB Dongle or Downgrade) for all consoles (fat & slim).

1. Replace following files on your consoles /dev_flash/ with the ones included in this archive p3dwik-ps2compatfiles.rar
2. Get into Factory Service Mode (FSM Tool/Dongle)
3. Insert your Original PS2 Game Disc
4. It will run.

Note: Backups won't work. You're getting the compatibility of the 2.60 software emulator with all of its bugs.

A possible compatibility lists:

PS2 Compat. flag

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.

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."

Those interested in running PS2 games on their PS3 console may also wish to check out the previous Open PS2 Loader v0.8 for PS3, PS3 USBLD Loader Source Code and USBAdvn Patcher and PS2 HDD Support & Discless ELF Launching from PS3 XMB articles as well.

Finally, in released news IngPereira has made available a PS2 DEX Boot 4.11 4.20 (Test) and below is also a PS3 EVO 1.0 video and release details by SONIC_BH for those interested, as follows:

Hi I just make a debug app that use some syscalls to do a reset into PS2 Lpar like boot_ps2 does, it should work on dex 4.11 or 4.20 but in these fw there is ps2 netemu instead of softemu so i need someone with an original disc of playstation 2 inserted on bd-drive and launch this test app and see what happens.

I am on 4.11 DEX but i don't have any original disc from PS2... This is basically the same thing that boot_ps2 does on 3.55 but there is a new emu file on dex 4.11 or 4.20 introduced on 3.70 with the use of PS2 Classics on PSN... This is not brick-risk, thanks to anyone who help me with this. Greetings...




1st - Download the file
2nd - Copy the file PS2 Evo v1.0.pkg to the root of a USB drive formated in FAT32
3rd - Install the .pkg from *Install Package Files*
4th - Insert a original PS2 disk on the BD
5th - Run the app and enjoy

yeah, this emulator is old and does not work well but it's a good progress still. more interested in PSP emulator working, that works better from Cobra.

the real hope for PS2 emulation on PS3 is hacking the new emulator being used in the new PS2 PSN classics. Those are working great.

Yes, cool. But how will the games play.

I already tried playing PS2 Original games using Cobra on Non BC Compatible PS3 and it sucks big time believe me. I can't see this method any better, but who am I too say.

PS1 Original games play anyway on any PS3.

it should. it just bites the compatibility is less than stellar. i mean, the psx one is near perfect, so i imagine with some tweaking, people should be able to boost this on up a little more.

Finally , funny thing is I just bought the game XIII for my PS2 but just realized my memory card was stuffed up so I couldn't save. Hopefully this will work well.

This well let me play original PS2 games on my PS3 though, right?

In Win 7 , make sure to Choose driver manually.

When you choose manually, only go as far as C:\Cobra USB\Cobra-USB_Updater_v2.0\driver, then click ok.

You can also install the PS3 updater, and update on your PS3 as well.

I don't believe it works for homebrew created into ISO. Have you actually tried a PS3 Game created into an ISO image.

I use genps3iso_v2.0 to create it on my pc.

Hi Guys,

i am following the scene for a while now and I am very glad I found this forum. It helped me a lot. Thanks so far...

I am facing an issue with my cobra usb dongle. I am trying to get a ps3 iso running via nethost and it just don't work. I even created a ps3 iso with the PS3 and transferred it to the nethost. But it won't start. I always get an error message, that this operation is not allowed. See attached error message. I am an absolute noob and am not able to find out the root cause. Maybe it is an easy issue. Please help.

Thanks in advance
