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)

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

7 - 3 - 2015 Cobra ODE News - Update

We are pleased to present the Cobra ODE FW 2.4 wich properly adds support for the Emu USB QSB and addresses a number of small bugs we found in particular with the drive door support for 4k consoles. We have updated the DMC triggering mechanism for enhanced performance.

The game database file has also been updated to include many new titles.

We are unable to fully support FAT PATA consoles with DMC owing to issue with BD recordable media compatibility and a multitude of different bluray drive daughterboards. FAT SATA consoles with BMD-31 will remain supported. If you have purchased DMC for PATA FAT consoles, you may return it to your reseller for a refund.

DMC will be kept fully supported on FAT SATA (BMD-31), 2k/2k1, 2k5 and 3k consoles.






Since we have removed the Hardware Passthrough mode from ODE FW 2.4, we suggest that users use ODE FW 2.2, if they wish to update the OFW of their console to 4.66. ODE FW 2.2, still has the option to enable HW Passthrough mode providing you are using the USB Clip on PCB. After updating the console OFW to 4.66 you can update to ODE fw 2.4 again.

Finally, from coalchamber1022: (DMC + OS 4.7 + CECH-2001A)

Hi Guys, Formalities...

I got things hooked up, loading a game is still a bit of a PIA but it works.

  • After plugging in my HDD with my games on it I plug my PS3 into power then boot it up.
  • I then put in by Boot disc I see the cobra menu and select a game.
  • I then get a what looks to be a video of just the cobra icon at that time I eject my boot disc then just put the boot disc back in. It then loads up the game selected in the XMB
  • I then hit 'x' to start the game the bootdisc then pops out then the ode flashes red/blue so i leave the boot disc and let it suck back in.
  • Then in a few seconds it ejects again then ODE flashes green/blue I then pop in swap and BADABOOM it loads up.




With that many ejects and loads I am anticipating my BD drive to crap out soon. Hopefully cobra team can lower the number of ejects but in any case it works!!

I just upgraded my old Cobra to a newer updateable version today!

On 4.66 it seems Sony are catching and winning the race with ODE's. Anyway, I do have a swap disk which means I am sorted for now...

All Cobra ODE users should avoid updating to OFW 4.70 until Cobra Team has carried out extensive testing.

Some videos on 4.70:

Multiman shares alot of info between the cfw cobra port which made me look into the issues with controller synch n are all within mm causing issues due to certain files where synch needs to be patched properly in with the file.

I already ran the tests and intact does work correctly thus also giving back the exit screen
