I originally posted this in freddy's psn tutorial, but I'll be able to manage it better from here. Several people have messaged me asking how to do this, so here you go: If you want to make your psn games into isos that will boot in Cobra, you can either using 3k3ys tool, or make them yourself. Ive had a few games that 3k3y tool generated not working .isos on the Cobra ODE, and when i remade them myself, they were fine. I didn't come up with how to do this, I just watched this video: http://gbatemp.net/threads/how-to-co...o-3k3y.353402/, which includes no written instructions and the gentleman speaking has a thick accent. I don't play online, so no guarantee that this is 100% safe, but this should be exactly what the 3k3y tool is doing. Tools you'll need: -PS3Tool (need PkgView, PARAM.SFO editor, and PS3 DISC SFB EDIT, all included in PS3Tool) http://www.aldostools.org/ps3tools.html -a hex editor (I use HexEdit) http://www.hexedit.com/ -scetool that will resign eboots (I've been using TrueAncestor SELF) http://www.ps3news.com/ps3-hacks-jai...now-available/ -unpack this rar, its the disc structure and files you will need https://anonfiles.com/file/8fd0f09dc0c4e1965fb7c1b56fc92e13 -psn game looking to make an .iso CREATING NECESSARY FILE STRUCTURE -*NOTE - IF YOU DOWNLOADED MY RAR PACKAGE, YOU CAN SKIP THIS STEP! To begin, I create a directory for use with all the files I'll need that aren't included in the PSN game. I grab them from my known working game. I use Resident Evil 6 [BLES-01465], but the game is up to you. So create a directory, I just call mine PS3FILES needed. In the root of that directory, you need to copy over the PS3_DISC.SFB file from working game. Create in the root directory two new folders PS3_GAME and PS3_UPDATE. Not all games have an update file, but the directory needs to be there. Go into PS3_GAME on your working game and copy the LICDIR folder to the PS3_GAME folder you created. Now you've got the basic structure setup, so you can copy and paste into each PSN title you are working on. ASSEMBLING GAME - Copy the PS3FILES folder you created into your PSN game folder -If your PSN game is in pkg files, open PS3 Tools and use PkgView to extract them to source folder. You'll usually have two .pkg files, one that is the game, another that is a crack or fix. -Once unpacked, apply crack or fix as normal. Now you'll have a PSN game. Open the PSN game folder, and copy the contents into your created PS3_GAME folder (inside PS3FILES folder you copied over). The files you'll have should be a USRDIR folder, some .png files, and PARAM.SFO, sometimes more directories. EDITING PARAM.SFO -Open PARAM.SFO using the PARAM.SFO Editor in PS3 Tools. It will load with the correct information, giving you the title ID of the game (remember this!). We need to change one thing, next to Category: you'll have a drop down box that likely says HG Harddrive Game. Change that to DG Disc Game (blueray), and save overtop your existing PARAM.SFO. Now is a good time to check the extra directories, sometimes they'll include another PARAM.SFO that needs the same edit (usually directory c00). EDITING PS3_DISC.SFB -open the PS3_DISC.SFB from your root directory with the PS3_DISC.SFB tool from PS3 Tools. It will give you a game title ID that isn't for the PSN Game you are using. Change the title ID to the PSN Game ID you got from PARAM.SFO, and save the file. EDITING LIC.DAT WITH YOUR HEXEDITOR -open your Hex editor, and then open the LIC.DAT file that is in the LICDIR folder. You'll have to scroll down, and eventually you'll see a PS3 game title ID. Replace that title ID with your PSN title ID, and save the file. RESIGNING EBOOT.BIN WITH TrueAncestor -Cut and paste your EBOOT.BIN file in USRDIR folder into your TrueAncestor folder. In your TrueAncestor folder, if you hold SHIFT and RIGHT CLICK, you can open a command window. Otherwise get there however you would. Enter this code and press enter: Code: scetool -d EBOOT.BIN EBOOT.ELF You'll get feedback, sometimes it says that it skipped decryption of certain sections because they contained no data. The last thing it will say is that it created an EBOOT.ELF Now Enter this code into the command window and press enter: Code: scetool --verbose --skip-sections=FALSE --sce-type=SELF --compress-data=TRUE --key-revision=0A --self-app-version=0001000000000000 --self-auth-id=1010000001000003 --self-vendor-id=01000002 --self-ctrl-flags=0000000000000000000000000000000000000000000000000000000000000000 --self-cap-flags=00000000000000000000000000000000000000000000003B0000000100040000 --self-type=APP --self-fw-version=0003005500000000 --encrypt EBOOT.ELF EBOOT.BIN (This should be all one line of text) You'll get feedback like this: Now you can cut and paste your EBOOT.BIN back to USRDIR. It creates the EBOOT.ELF file, which you can copy over if you want to, but it isn't needed. CONFIRM FOLDER STRUCTURE AND MAKE ISO Make sure folders are correct. It should look like this: Now generate an .iso using GenPS3Iso! Load .iso onto your external HDD, and id you are using Cobra Browser, follow SDeath's tutorial to set that up at this link: Tutorial: How to Create COBRA BROWSER. I know it looks like a lot of work, but once you get used to it, it's not that bad. The alternative is to us 3k3y to generate the iso, and if it doesn't work, try making it on your own. ***somethings the community has learned since I originally wrote this: 1. PS1/PSP games that were purchased off of PSN do not seem to work, they have a different file structure. I'm working on this in my spare time. 2. PSN games requiring you to move a file to the internal HDD will need to have that done seperately from this, and on OFW some of those directories are not accessible. ***future updates 1. Add more screenshots 2. Perhaps video of the process Start keeping track of PSN titles that convert to .iso using this method so we know which works and which don't.
