From the included ReadMe file: Just place the .exe file in your flash drive where you have your folders and cfw setup run it and it will tell you if there is a typo, the foldername correct, the pup name correct and then if so it tell you your ready to go.

From eminem451 also comes Check_PKG (linked above), who states the following:

Hi, a quick tool to check if your PKG is not altered. This will verify a single PKG file or a whole directory.

Options:

There are x86 and x64 version in the zip, use the one you need.

  • check_pkg: only return a code (0 = OK, anything else = ERROR), more usefull for dev using other app calling it.
  • check_pkg_dbg: same as "check_pkg" but outputs messages.
  • check_pkg_dbgc: same as check_pkg_dbg but PAUSES after any errors when checking directory and has a progress bar, better of the 3 releases for common user.

Check_pkg_dbgc is recommended for common user. Use this after downloading a PKG to be sure it is not corrupted.

Update: I updated my software, it now handles debug PKG better, and can check ECDSA signature from retails one.

HashCalc

Hi, I made a little app (linked above) to calculate hash from files. i limited it to a few algo for this edition, let me know what you think of it.

Info: Drag and drop file on it will save time.

  • If you are on win8.1, right click on hashcalc.exe, unlock.
  • This app handle mode than 200 hashing algos; i locked it for this edition (SHA3, MD6, BLAKE...), making it easier for everyone.
  • With this app, you can compute MD5 or SHA1 of any files, it may help you checking PUP's MD5 for example.

HMAC is available on full version, tell me if you need it.

Info: Not all algos are listed alphabetically, it's normal, i sort them myself, sometimes alphabetically and sometimes by genre, there is no problems with it.

On 21/12/2014, removed French version, removed X64 Version, this way, there only is one version. A few bug fixed.

Version 1.1.3: Unlocked PS Debug PKG Hash, there are many hashes in debug PKGs, first one is stored at offset 0x80, use my app with this algo and set size to 0x80, check then hash in file at offset 0x80, if it matches, PKG is OK, else it wasnt built correctly or was altered.

I noted that, debug PKG made by proper tools (SDK ones) have good hashes, a few others, i think made by that ugly python script dont. Any PKG made by make_pkg_npdrm (official) has these hashes correct.

EAHash Unlocked too, a md5 derivation used in some game saves.

Update 1.1.3 Changelog:

  • Added PS3 Debug PKG Hash algo, EAHash, and a few UI bug fixes.

Can this decrypt 3.6+ eboots? If so then we can start making our own 3.55 eboots.

Following up on his previous release, this weekend PlayStation 3 developer PsDev has updated PS3Tools GUI Edition to version 2.0 which now incorporates the PS3 EDAT Tools with the complete changelog detailed below.

To quote: I collaborated now listen, PsDev back with the brand new edition. Yes, yes. Me and SnowyDew have collaborated and I added his magnificant tools to mine It was a struggle getting it to execute properly, but I finally got rid of all the errors and combined them for the best experience.

  • Changes, Decrypt and Re-encrypt edat's successfully
  • iso.bin.edat extraction
  • Decrypt eboot.pbp's / eboot.bins for further game modifiying
  • Decryption of act.dat and rif keys
  • Print coreos image info

Snowydew: so the decryption as it stands right now, an do iso.bin.edat, requires idps, rif and act.dat for the games. re-encryption i believe it needs the “fake” signed ones, as well as an idps (not sure on the idps) however the second method only requires the idps and the .rap file. this does not cover licenseing games i believe (It could, but we haven’t tested it) the re-encryption algo is in the encryption one, but again haven’t been able to test it completely (reason I was asking around on twitter awhile back)

Thanks to naehwert, snowydew, KaKaRoToKS, geohot, math and any one else I forgot.

Finally, in related news today belioc has leaked what he claims are some PlayStation 3 Lv0 Opcodes (below) and has credited PsDev for them, as stated below:

Although I am leaking this, I am still gonna give credit to who got these, that is PsDev. OpCodes (Operation codes) are the operation to be performed in a instruction set of the processor.

Here are the lv0 operation codes. A lot are unknown so it's really hard to say what function they're doing, but the function offset is provided. When I recieved the file it has about 10MB of NOP (No operation performed) about 1MB of operations being performed.

First Set:

Second Set:

Shortly afterwards, PsDev stated the following rebuttal though: Lol this is false, me and naehwert talked it over the opcodes are just a reading that is false due to the lv0 being encrypted. the BL is what decrypt the lv0. How would I dissemble a encrypted lv0?

Haha last time I share something that could have potential (it don't) with someone.

Just run the lv0 in a DisArm decoder (don't have to be DisArm) it will bot the self and tell the opcodes (that are false).

Thanks naehwert. Good bye.

We need 3.60+ keys to decrypt eboots, the parts of newer firmwares (i.e. loaders), etc... This tool lets you do everything you can do today with the convenience of using a GUI.
