Requirements:

- A Sony battery
- A memory stick with a capacity that is less than 4GB. 256 MB minimum required
- A PSP with Custom firmware (SE, OE, M33, etc...) or a PSP with 1.50 installed

Procedure:

Creating the Magic Memory Stick and JigKick Battery
1. Connect your PSP to your computer via USB mode
2. Format your memory stick. MAKE SURE YOU BACK UP ANY IMPORTANT FILES!!!
3. run the mspformat utility through a Command Prompt.
4. Eject your Memory Stick from your PC and disable USB. Then reconnect to PC.
5. Create the folder PSP/GAME or PSP/GAME150 depending on your firmware.
6. Copy the battery and installer folder to your newly created folder.
7. Copy the official 1.50 update eboot named as UPDATE.PBP to the root of your memory stick.
8. Eject and disable USB mode.
9. On your PSP run the installer program. This will install the firmware files on the root of your memory stick. It will also create msipl.bin.
10. Connect your PSP to your PC once again.
11. run the msipl.bin file. When it's finished disconnect your PSP from your PC.
12. Run the battery application on your PSP. THIS WILL PATCH YOUR BATTERY!!
Note: If you want to use your battery for normal use again just run the battery program and press Triangle button. This will back up your battery to your memory stick. I highly recommend doing this!

Once it's finished you will have a Magic Memory Stick and a JigKick Battery!

Using your new tools

1. Insert your Magic Memory Stick into your PSP
2. Remove Power Cord and insert JiggKick Battery
3. When you power up the PSP a menu will appear. Just follow the on screen instructions.

To restore your Battery to normal state:

1. Remove Battery from your PSP and power up using your AC Adapter
2. Run the battery program and press L+R to restore your battery. Make sure your backup is in the root of your memory stick!
