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:

  • tortuga-cove.com/forums/viewtopic.php?f=57&t=530
  • ps3devwiki.com/wiki/Talk:Emulation#PS2.2FPStwo

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.

Result examples:

In binary formation:

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.

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

The strings from cobra.elf


From CrashSerious: Case in point: (first 8 lines of the cobra driver)


The device ID and Vendor ID should be useful eventually, but it's so easy to get I'm not sure it's worth mentioning. (Though, it is documented in the wiki.) The device GUID is simply a windows thing so the libusb drivers can be found in the registry, etc.

From lewy20041: Cobra PC update and Debugging Tools for Windows

I have used Debugging Tools for Windows when the proces cobraflash.exe were used to flash Cobra-USB_Firmware_v5.0.cba to dongle and here is the outcome to open this file you need to install Debugging Tools for Windows. maybe some one can look at this. there are wery interesting info about cobra update process on pc.. have fun.

Some of it:



I used 7 zip on cobra.elf ([Register or Login to view links]), inside there are some more files without extensions.. ran it in ida pro and they are also regenized as PPC elf 64 and now the strings look little different: [Register or Login to view links]

From blazek566: Got this from the cobra1 file.. tell if its any good [Register or Login to view links]

Finally from zadow28: Been testing my new tracker on the cobraflash and got some visual results with big difference in security. you can see the results here.

first download: [Register or Login to view links]

small guide to open the visual files, then download the visual files: [Register or Login to view links]

just open the files with the guide. i would recommend cobratrack first. blue spot is start, and you scroll in with mouse. this is from start, too when i load the different images.

its show the way with fake loops, as they are in the software (encryption) the path. it speaks for themselves.
