Decryption of EDATS
Three ways to do it:
- act.dat,rif,idps combo
- rap
- free content (npdrm1 klic)
Free Content
Simply decrypted with appldr keys and free klic
Using RAP
Overview of steps:
- Obtain rifkey from rap (flatz's rap2rifkey)
- Decrypt EDAT using corresponding klic (minis,psxclassics,etc) and rifkey
