After searching for those missing bytes I did not found any reference on code. So I zeroed them and feed the file to the PS3... The file was properly loaded and decrypted so:
-Those bits are a random padding or
-They are not checked ,nor required for creating an EDAT.

That means that you are able to "free" your EDATs using the method above.
Remember that you're going to need the devklic and the rifkey

@Octopus For p3T you don't require the devklic cause for paid decryption you only need the key from rif... so decrypt it and use it directly like any other theme

@EXE.trim.ALL You're right on version. LV2 uses that value to check which flags are valid. However unk4 (and unk3) which are at 0x70 are zeroes. Your info is for the next 16 bytes located at 0x80. Also you separate finalize and type. From the assembly I can say that the original source code considers it a signed integer (int32_t) (that or they have a really weird compiler cause it always load that field as a word (PPC can read a single byte)).


BTW the text on flowers says something about "werewolves" and the devklic
is written as an ASCII text (not binary). It was the first non free content that I decrypted on PC.

@euss IMHO best topic of the last half year was written recently by math on lan.st...
half year? nah... last year.
It's a pity that I would never enter on efnet (nor other sites) as long as they don't allow proxy and TOR.

Finally a bit of drama: Hotz8611, I reversed your reactPSN to see the your method and discovered that you just used the info on this post. I haven't check the vsh.self mode but I suppose that youre nullifyng the curve check and generate RAP by encrypting the rifkey (An AES and another crypto algorithm of 5 rounds with shuffle, acummulation and xoring.). I thank you for making people provide me all those RAP than I'm able to transform to rifkey but next time give proper credits (I don't know if your works is based on mallory or mine but obviously is based on info in this topic).
