Guide to decrypt EDAT files

[jacky400]

i just tried it to decrypt a EDAT file from Jetpack Joyride , seems to be not working .(npdtool is fine)

E:\rpcs3-master\npdtool>make_npdata -d jet.pak.edat output.edat UP4249-NPUB31097_00-JETPACKJOYRIDE00.rap
NPD HEADER
NPD version: 4
NPD license: 2
NPD type: 0

EDAT HEADER
EDAT flags: 0x0000003C
EDAT block size: 0x00004000
EDAT file size: 0x00BAB567

ERROR: A valid RAP file is needed for this EDAT file!

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 .
