to use a memory stick duo.
i found something on afterdawn telling you that is possible to use a 32mb one, by formatting it in a certain way.
however mine is 64mb so formatting in this way does not work.
Here is how you can use a 32MB Memory Stick Duo for the Pandora's Battery:
- connect your PSP to USB
- run cmd.exe (Start -> Run -> cmd)
- type 'format e: /FS:FAT' (E is your PSP drive letter!)
That way the Stick gets formatted with FAT16 (instead of FAT12, which doesn't work). After that, you may continue the normal procedure (mspformat, msinst etc.) an that 32MB Stick!
Cool, eh? Everyone has such a 32MB stick lying around. Now you can use it for the Pandora battery!
