RE: Guide to decrypt EDAT files - Ekaseo - 06-23-2014
Hi, could someone post a guide on how to decrypt EDAT files?
RE: Guide to decrypt EDAT files - jacky400 - 06-24-2014
The simplest one would be using npdtool
For example key.edat
npdtool dr key.edat output.edat <rap key>.rap

I built it for anyone who needs it: https://mega.co.nz/#!Bg9DwAqZ!uqWBaSjXHFuJSquzUaGMYZfBInU3y-Cl9w8Z1xzuPyw
(Hint: On Windows 7, shift+right click in the folder where the .exe is, and open a terminal/command window. Then type make_npdata.exe (type just that) and you will see the program usage, without a terminal window that exits when the program is done, so you don't see anything...)
Or look at this I guess

i just tried it to decrypt a EDAT file from Jetpack Joyride , seems to be not working . Probably flag 0x3C and 0x3D are unsupported yet.

You have to specify klick also.
make_npdata -d input output klick rap

Thanks it is okay now . The source code of make_npdata seems to be supported 0x3C flag though not yet on RPCS3 .
RE: Guide to decrypt EDAT files - jacky400 - 07-04-2014
Just reminder for anyone if you are going to use npdtool , make sure you are using npdtool fix 2 , otherwise the EDAT decrypted will not be able to use with RPCS3
The best would be using make_npdata that should work straightly.

I have a problem after decrypt .edat it makes me that
LDR: E PPU[1] Thread (CPUThread)[0x02831160]EDAT: File has invalid NPD header.
What does that mean?
