Playing PS2 backups
As of version 2.0, playing PS2 backups is only supported in CECHC and CECHE models. Support for CECHA and CECHB models will come in a future update. Currently, ps2 backups can only be loaded from internal disc, and not from external drives or optical discs. You can however transfer backups between them.
1. Start Cobra USB Manager from XMB.
2. Press square four times to change to PS2 mode.
3. Choose the backup from the list and press X. You need a disc inserted. Any type of disk will work.
4. Cobra USB Manager will mount the backup and exit. You can start the ps2 game backup from the XMB. Don’t forget that you must assign slots to virtual memory cards in the XMB if they aren’t already assigned.
The first time a ps2 backup is going to be played, you will be prompted to install ps2 support. This process overwrites some system files. The overwritten files are not critical for ps3 booting. This process will cause ps2 games not to work when PS3 is booted without Cobra USB jailbreak. This can be undone at any time by doing a 3.41 -> 3.41 downgrade. This warning will appear too in Cobra USB
This side effect won’t happen in Cobra port to 3.55 version.
Cobra USB Manager uses the following directories for PS2 backups:
Allowed format are:
· DVD backups: iso files with 2048 bytes per sector.
· CD backups:
1. ISO files with 2048 or 2352 bytes per sector; CD backups with 2352 bytes per sector are
2. Cue+bin: Data track must be mode 2/2352.
Cue+bin+wav is not supported: audio tracks in wav files are ignored.
PS2 iso backups are automatically unmounted when returning to XMB from the game.
Because of the special nature of the PS2 emulator, the jailbreak exploit is run automatically again when returning to XMB from a PS2 game or when turning off the console from the PS2 emulator menu. When doing any of those operations, make sure that no usb device is inserted except Cobra USB, and that Cobra USB is in jailbreak mode. If you fail to do so, you will return to a normal not patched 3.41 XMB. This issue will disappear in 3.55 port of Cobra.
Currently, there is no support to load original games from different region. However, backups in iso are region free, and the ps2 emulator successfully switches to the proper frame rate. The regional lock of original discs doesn’t apply to making backups; you can backup your regional locked game and play the iso backup.
Settings menu can be entered in Cobra USB Manager by pressing R1. Use left-right to change settings.
Currently, the following settings can be changed:
· Blu-Ray region: you can fake here the region for blu-ray playback, allowing the playing of movies of different regions. This process doesn’t write anything in the system flash, region is only faked when starting the console with Cobra USB.
· DVD region: you can fake here the region for DVD-video playback, allowing the playing of DVDvideo of different regions. This only applies to RCE protected titles, standard DVD regional protection is already bypassed by Cobra USB. This process doesn’t write anything in the system flash, region is only faked when starting the console with Cobra USB.
· Games launch mode: you can change here how games are launched. XMB mode means that Cobra USB Manager will exit back to XMB when selecting a game and you must start it from XMB. In direct mode, Cobra USB Manager will launch the game directly, this may lower compatibility.
· PS2 Software emulator: this option appears only on not backwards compatible models. If enabled, users of these models can test ps2 original games and backups in iso format using the ps2 software emulator.
This option is disabled by default because the software emulator doesn’t have much quality; it is slow and has several problems like virtual memory card not working, graphical glitches, and hangs. In ps3 slims, it has some additional problems, like controller only working if connected to an usb port.
Once this option is enabled, users of not backwards compatible models can follow the instructions in the PS2 sections to load and make backups.
Blu-Ray region, DVD regions and PS2 software emulator settings are saved on Cobra USB internal flash. If you have removed Cobra USB, please insert it again before saving settings. When inserting Cobra USB again in the PS3 after having been
