boot it up again and copy "pan3xx" aswell as "despertar_cementerio" to PSP/GAME/(create these folders), and then copy the OFWs to the root of your MS as
150.PBP, UPDATE.PBP(this is a copy of the 150.PBP but renamed), 340.PBP and 380.PBP.
run "Pandora Installer for 3.xx -R3-" again and select "X to install 1.50 firmware, containing Pandora, to the memory stick" and wait for it to install the firmware to the MS.
now press "L trigger + X to install msipl.bin to the memory stick."
once done, it will exit to the XMB.
now select "Despertar del Cementero" and press X.
Now, fow what i'm thinking, since my MS already has 1.50 firmware installation (using Hellcat's Pandora Installer for 3.xx).
I will just paste the DCv5 in the game folder and run it. i'm expecting that i would have MMs with DCv5.
Is it right? if it is wrong please tell me what to do.
