44w ago - Just a few days since his PS3Tools GUI Edition v3.0 release, PsDev has now updated the homebrew application to version 3.1 which includes PS3 SPU emulation changes, .SELF encryption and more as outlined below.
To quote: Just finished my latest update for PS3Tools GUI Edition. I added quite a bit of changes in this version, scroll down to the Change log to see.
.SPU is now extension for emulator
Edit SPU files for emulator
Save SPU files for emulator whilst the program still open for faster emulation
A label that tells whether it’s currently emulating or not
SPU emulator has message boxes now upon successeions or errors
SPU refreshed button fixed
Changed interface for LS and codewatcher
Debug pkg decryption temporarily removed
Checks pkg type now
SELF encryption added
Filter added to opening SPU file on editor and emulator so it narrows it down to just .SPU files
CEX2DEX now will tell if validation is done
Test.SPU included for testing
Included missing .dll for SPU emulation
I had some reports the Debug pkg decryption wasn’t working, so I removed until further notice.
# to make a comment use #
This is how to load a file
#elf,file.elf,true #the ext first the comma then the file name and ext.
#place the file to load in program folder
#now just load this test.SPU file and in r3
#here is how you would test a register
#r,3,0,0xdead0000 #meaning r3 #shows in leftside
Nice little example I made up, I commented on it to give you a little understanding. Still gotta give props to KDSBest for original creation.
Finally, below are some guides from PsDev (via psx-scene.com/forums/content/tutorial-2471/) for those interested:
PS3 PUP Unpacker:

4. Now click do it and your down, you will receive a output like below:
1. Name the PUP "PS3UPDAT.PUP"
2. Click the drop down menu in PUP Tools
3. Click Dev_flash unpacker, and hit Do It. You will get output like below (Note, It will be a lot longer, that's just a example):
1. Just place one of the following, lv0, lv1ldr, lv2ldr, appldr, isoldr or EBOOT.BIN in root of program folder

PKG Key: F8 72 19 EC FE 95 EF 1F 51 22 3D 04 A3 E2 37 5E
PKG IV: F7 1E 03 B6 9D 5D 74 D7 7B 03 F6 14 00 00 00 00
PKG Size: 7340000 bytes (7.00 MB)
Fix Tar Tool:
1. After modifying the tar file you need to fix it for it to be correct, so have it named "Update_files.tar"
2. Click drop down menu
3. Click the following options on the screen that apply to the tar you want to fix
4. Click do it, you will get a output similar like below:
1. Have the original name of one of the rco that are optioned in the drop down menu
2. Make sure that specific rco file is in your root of your folder
3. Click it then click do it, you will have a dumped rco in RCO folder along with following output:
1. Have the eid_root_key named this "eid_root_key.bin"
2. Name the Flash or your Nor, CEXFLASH
3. Have openssl installed under C:/opensll
4. Then click drop down menu
5. Click only option
6. Click do it and get output plus DEXFLASH like below:

The Appldr from 3.60 + firmware has been encapsulated in lv0. So we must first access the lv0 (not yet decrypted). In firmware 3.60-instead appldr is independent of other processes. If you change the system so that the install package files installs games appldr using of the firmware 3.55 (which we know keys), so installing a backup managers, which mounts the boot path of the games and then uses the appldr of the firmware 4.00.
That system uses 2 processes appldr, the 3.55, which installs the homebrew, and appldr (that of the Sony OFW) who starts the game 4.00.
A CFW obtained with a scrum of the various self of the core_os (4.00 and 3.55) but with a bit of reprogramming, so that uses two processes, depending on the function
Can unpack any "PS3" Firmware up to date. Gets really fast after first or second use.
A console is built into the program showing you the exact log a cmd would.
Can Decrypt PS3/PSP retail PKG files (Signed by sony installable via OFW).
Can readself of, Appldr, lv0, lv1ldr, lv2ldr, isoldr, EBOOT.BIN or if any of the things that you want to read are not listed on a button you can run a custom command to do it, for example: aim_spu_module.self just type that in where it says input and it will read it. So any file that is possible to use via readself, can be done in a fast manor 1-2 sec.
A full featured .Conf editor. view .Conf files edit them then hit save button when finished.
A awesome Core_os_package tool that can decrypt, extract and encrypt the Core_os_package.pkg all in about 1-2 sec.
Sign pkg for 3.55 or 3.41
UnSELF a file.
Build SELF a file.
Whenever a tar file is modified, it's permissions need to be set, this tool can do that for you. fix the tar file for the following FW. retail fw up to 3.72, debug fw up to 3.72 and retail and debug fw 4.0.
Lets use a example: If you want to unpack a ps3 update just get the PS3UPDAT.PUP
(Don't change the name of any file in ps3 FW keep original) and put in tool folder, run my program click unpack and it will unpack it.
So like if you want to fix tar make sure the update_files.tar stays the same name and put in the main folder where program is located. same for anyfile keep the original name. So it's pretty simple just drag the file that you want the tool to do something with and keep the original name.
Here is a video I made (I am pretty bad a videos) to help it' a tutorial that covers everything. If some one else could make a better one that would be awesome.
Notes: PS3Tools GUI Edition will create two new files for the Core_os_package. "decrypted_core_os" and "CORE_OS_PACKAGE_ENCRYPTED.pkg" don't change the name of the decrypted one or else you won't be able to encrypt it
BETA Tester Thoughts: Tested by jhax78
All those command line tools that takes loads of time and sometimes commands that you need to understand will be replaced by this 1 click tool, even a trained monkey could extract repack sign with this now.. it's taking literally 3 seconds to extract a pup resign or whatever you need to do.
I'm no dev but like to poke around in stuff and i think more ppl think like this with this tool all that is just peanuts now.
Developer PsDev is back again today with another article (psx-scene.com/forums/content/possible-1885/) for everyone to read and enjoy. This time, the topic revolves around a possible PS3 4.0 exploit, and the theory around it. This is information that he would like to share with the scene, in hopes of change and overcoming the current barriers to jailbreaking the PS3 console. Feedback welcomed, as PsDev has put a lot of thought and time into this theory.
OK so lets get right to it. This is a theory, nothing more.
There has been information available for quite some time. and I took it, thought about it, researched and experimented and I come out with my theory below to exploit 4.00 part of the way. This is not a random theory to, this is logical stuff and true facts. I'm providing this info for other devs to look at and lets see if this can work. I don't keep my work to my self, I like to share in give other people chances in discovering stuff. It always makes me happy when someone finds something out using my work, it just tells me I did a good job in describing and helping and they did a good job in listening and learning the material in order to trigger the exploit or whatever it might be.
So the lv2ldr verifys decrypts the lv2_kernal.self. we can get the address of this happening. inside Parameters Layout there are arguments, they are used as commands basically to load a function you want to use. they start in the lv2 @ 0x3E800(seems to be same for other ldrs) that address. There is a argument that is called lv2_in and lv2_out (we have know about these) basically we can use lv2_in to map out the address and lv2_out to map out the address for where the lv2ldr decryptes the self file.
We can make a program like readself basically and get the offset, u8* means read one byte from the address. use that and we can actually be get the exact offset where it all happens at. once we have the location grabbing this decrypted self should be the easy task. Like I said some info we had and some we did not know about can be obtained like this and used to get keys.
exploiting 4.00 with this method would work most likely because I doubt sony changed all the locations where the loaders do there thing, sure there encapsulated in the bootloader but they still pass over into the ram at one point before being fed over to the metldr which loads ldrs and if all that is still happening then Sony didn't change nothing.. some where along these lines:
