How to install Pandora Battery Files ( Despertar del Cementerio v3 by DAX) on your Memorystick (needs custom firmware)

Stuff you will need:

• Homebrew compatible PSP
• USB cable for the PSP
• The following files:
  
• Computer(with administrator account)

Installation:

1. Download all the files above, and extract them.
2. Copy all the files you just extracted to "C:".
3. With the MS inserted, connect the PSP with custom firmware to the computer, via USB Connection.
4. On your computer, go to start, click run, and type CMD.
5. When the command window appears, type
   cd C:\
6. Then type
   mspformat.exe X
   Make sure you replace X with the drive letter. In the picture, my PSP is in drive F. Check which drive your PSP is in by going to My Computer. I would type mspformat.exe F
   
7. You will now get this message:
   Drive successfully formatted, and partition moved.
8. Close the command window. On the PSP, disconnect from the computer, and remove the memory stick. Put the memory stick back in the PSP and reconnect to the PC. This step is important.
9. From the folder you extracted on the first step, copy the folder called PSP to the MemoryStick.
10. Rename the 1.50, 3.40, and 3.71 updates as 150.PBP, 3.40.PBP and 3.71.PBP.
11. Copy them to the root directory of the PSP ( what appears when you double click the icon that's ringed in the picture).
12. On the PSP, disconnect from the computer, go to GAME>MEMORYSTICK> and run the program that appeared there.
13. When it's finished, connect the PSP to the computer again.
14. Click Start, Run, and type EXE.
15. When the command window appears, type
    cd C:\
16. Then type
    msinst X msipl.bin
    Like above, make sure you replace X with the drive letter. I would type msinst F msipl.bin
17. A long message will appear. Type Y and press enter.
18. Write MS BOOT CODE will appear.
19. Close all windows.
20. Congratulations, you now have a Despertar del Cementerio Memory Stick.
