If anybody wants to have a play with this app, here are the 479 sdats from Hitman (decrypted and unsorted):
DecSDATS

Not as such, the application takes decrypted data and creates a V3 encrypted SDAT file that can potentially be used on 3.55CFW. 3.55FW does not have the keys and code to support V4 SDATs.

We have been able to decryption the V4 SDAT file ever since we have had 4.XX CFW. The decryption is done on PS3 running 4.XX CFW. You just write a program to use cellFsSdataOpen available in SONY's SDK. It is Sony's call to open an SDAT for reading. The code I linked to in the article extttdpk uses it.

The bit we have been missing until now is how to create a V3 SDAT, which I have now provided.

Looking at propJoe fixed hitman .sdats, it shows version 4.0.0 for SDAT, shouldn't it be 3.4.0 or something to work on 3.55? Any idea what he did with decrypted files to make them work on 3.55?

The SDATA 4.0.0.W string at the end is not checked as far as I am aware. The 8th byte of the SDAT header is the version and this is 3 for propJoe's SDATs. I can also decrypt them on the PC so they are V3 SDATs.

Oh, now i understand. So can i encrypt original V4 decrypted hitman SDATS with this tool to work on 3.55? Just to be sure.
