• Ps3 Dev jaicrab has released dumps of the CobraUSB Dongle. However, these dumps are not confirmed to be working on any dongle, but it is a step forward to playing your PSX ISO as well as watching region free BLU-RAY on all PS3 models including SLIMS. And PS2 ISO compatibility on BC PS3(launch PS3s).

    Here is a quote from the source:

      Hihihihi

      I wait for a Portage of the Dump on the E3 Card Reader.

      Thanks for the news

      When it says "PS2 ISO compatibility on BC PS3(launch PS3s)", is that literally only for launch PS3's (20 gig?), or would it also work for the 80 gig models? If i remember, my 80 gig has some sort of BC, but im fuzzy on the whole software emu vs emotion chip stuff.

      Launch meaning the early 20 and 60 gig consoles, and some 80 gigs like the MGS4 bundles. Only some titles on the 80 gig can run via software emulation as the emotion engine chip was removed by Sony to cut costs. by BC I mean BackWards Compatible.

      So no chance to get this work on KMEAW 3.55?
      Would be nice because i still have an ecliPS3 dongle laying next to me which can flash any Hex Codes for all Chipsets...

      I honestly would get more use out of PS2 ISO loading then PS3.... If it wasn't for my PS3 being the single best media player I own, I probably would sell it. Hmmm well my PC plays media better but the PS3 does it from the couch and the comfort factor cannot be under estimated lol

      Long live the PS2!!!! PS1 ISO's could be fun too SOTN and Road Rash FTW! hmmm yeah

      Jaicrab if you can make a .pkg for this noob or some one else makes it with your help I promise to create some kind of alter with candles and maybe some sort of voodoo good luck spell or something lol

      ALL HAIL THE MIGHTY JAICRAB!!! *bows fervently*

      you could also try a WD TV Live which is much more cheaper and supports much more video and audio formats

      If you only play DVDs and SD content just get an xbox 1 and hack it for XBMC.

      Supports allot more SD formats than the PS3.

      I think it is. Jaicrab may be implementing it in his CFW. I f you don't know about read about it on the front page

      I'm getting excited that the scene is getting closer to PSX backup support. In preparation for this, I've started creating backups of my PS1 and PS2 games, and I have some questions about the backup formats...

      1) Should I be creating an ISO or BIN files for these disc images? (I know that no one knows entirely for sure yet how this is gonna be implemented, but someone must know better than I)

      2) When creating an ISO, ImgBurn also creates a MDS file -- should I make sure to save that guy too or is it extraneous?

      3) When creating a BIN, ImgBurn also creates a CUE file -- should I save that thing too?

      Thanks a bunch!

      well cobra supports bin/cue pairs so i guess you will be ok. yes keep both, cue files are so small that won't even make a difference if they are not used, and i don't really think they are used.

    34. Benzonia

      So are BIN files better than ISO for backup play purposes? Does it make any difference at all?

      And should I even be doing the backups with my PC ahead of time, or will the implementation probably require you to insert the disc into the PS3 and rip the image from there?

    35. Pockets69

      glad everybody is focusing on this matter instead on the fact that all we have for the moment are just a couple of files that the end user can't use for any ps2 backups or anything else . . . guess that Optimism is a good thing . . . anyway as i have BC ps3 i also hope something will be out soon and we wont end up waiting for some variant of "Multiman experimental support for ps2 " that never worked for nobody till this moment considering time and all its updates

      Jaicrab has now released usefull information of the protective measures from Cobra Usb. This is for everyone who is interested in reversing the dumps.


      Translated with google:

      Flynn sent me this text explaining this protective carrying the Cobra, I hope it will open the eyes of those interested in reversing the dumps.

      EXPLAIN RTOC COBRA TRICK

      The JIG Cobra has several protective measures to ensure that your code could not be used correctly even if your code could be dumped.

      This trick rtoc in the registry is the first used for this purpose in addition to hinder analysis.
      Registration is initially rtoc stored in the battery to keep the rtoc of lv2 and power it back later:


      # =============== S U B R O U T I N E


      cobra_syscall_sm_shutdown_hook: # CODE XREF: syscall_379 j

      .set arg_20, 0x20
      .set arg_28, 0x28
      .set arg_30, 0x30
      .set arg_38, 0x38
      .set arg_40, 0x40

      mflr %r0
      std %r0, arg_20(%sp)
      std %rtoc, arg_28(%sp)

      At this point we have to explain that the OFFSET DELTA.
      DELTA OFFSET is a method used in the x86 in its original moments in the creation of computer viruses,
      to calculate the memory address in which we are in the sea of ​​bytes in RAM.
      In the original time a computer virus when I did not know where he was pulled into an executable,
      depending on the executable it could be an initial site or another, for it was invented DELTA OFFSET.

      DELTA OFFSET can be used in any system, the procedure is:

      - Using the record that indicates the current execution address (or the next depending on the system)
      - Reducing the size of the previous code we use the value obtained from the registry.

      Knowing this, and taking for example the x86 processor where the EIP register can not be read directly invented the trick
      make a call to a "subfunction" which is simply the following line to the call:

      call x
      x:
      pop eax

      X86 call instruction saves the top of the stack the address of the next instruction to itself.
      Thus using pop draw from the top of the stack this value, and stored in eax for example, and having the memory address
      where we only subtract the above would be missing and we have the exact calculation.

      The PowerPC can use this trick using the BL instruction is equivalent (LINK BRANCH), which jumps to a "subfunction" but before you save
      LR in the record the following address to BL.


      bl _delta_offset

      _delta_offset:


      At this point we see the trick used for the creation of the rtoc of charges at this time.
      If you look both r0 and rtoc are passed to 0:

      li %r0, 0
      li %rtoc, 0

      Subsequently, given the value 0x11DE0 to rtoc:


      oris %rtoc, %rtoc, 1
      ori %rtoc, %rtoc, 0x1DE0

      A r0 is given the value 0x920:

      oris %r0, %r0, 0
      ori %r0, %r0, 0x920

      R0 is subtracted from the value of rtoc:

      subf %r0, %r0, %rtoc

      Unlike the PowerPC x86 LR register can be read directly with mflr instruction, we put in RTOC the value obtained by the delta offset:

      mflr %rtoc

      To calculate the delta offset subtract final instructions executed before the delta offset, which were 4, or 16 bytes:

      addi %rtoc, %rtoc, -0x10

      Finally we add the value of r0 at the end of the delta offset RTOC, storing the result in the RTOC and this already takes RTOC suitable for this hook:

      add %rtoc, %rtoc, %r0

      It takes having the RTOC stored in the stack 3 arguments that the hook received:

      std %r3, arg_30(%sp)
      std %r4, arg_38(%sp)
      std %r5, arg_40(%sp)

      You call the function of the charges where the first argument will check for command 0x8202 (a special command to the usual):

      bl cobra_syscall_sm_shutdown

      After making the necessary steps as charged, the battery recovers the original RTOC, like the arguments the hook received, it executes the original instruction
      that was overwritten in the syscall entry 379 (in this case) to have our hook, and call the original syscall lv2:

      ld %rtoc, arg_28(%sp)
      ld %r3, arg_30(%sp)
      ld %r4, arg_38(%sp)
      ld %r5, arg_40(%sp)
      mfcr %r12
      bl original_syscall_sm_shutdown

      Upon returning to retrieve the original LR from the stack and returns to the prompt,

      ld %r0, arg_20(%sp)
      mtlr %r0
      blr

      # End of function cobra_syscall_sm_shutdown_hook
