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
