Help making Pandora's battery

[Tyrrell]

I'm going to create a Pandora's battery using my PSP phat battery running 3.40-oeA.

I've downloaded the pandora zip file off the net and am having trouble understanding some parts in the read me section. for the installation procedure, how do I:
- Execute "msipl" application on the PC with the msipl.bin to write the IPL to memory stick.

In the files that came in the zip folder there was only a msinst.exe, is this the excutable I need to be running and do I have to put it onto the PSP card before I run it.

I also saw somewhere that I should make a backup of the eeprom.bin file from the battery. how do I do that?

If anyone knows where an easy to follow/step by step directions for creating a pandora battery is, I would greaty appreciate it.

Also do all the old emulators still work, DGEN, SNES N64 etc... or are the coders still working on them.

Cheers:)

Thanks for the link. I followed the instructions and managed to make a battery. though when I went to downgrade my psp slim nothing happened but a black screen. I tried it with my psp phat and the "menu" came up asking if I wanted to downgrade. any ideas? also what is the nand (nand-dump.bin) backup for? should I create one?

The PSP Slim does not have the LCD screen driver support to display the menu for downgrading. It still works but it will only display a black screen. The controls for the downgrader on the Slim are still the same (X to install 3.60M33, square to dump the NAND and L+R to uninstall M33).

A NAND dump is what it says, a dump of the PSP's NAND. Creating a dump of your PSP Slim's NAND is a good idea as a method of making an un-repairable brick of Slim's was discovered a little while ago and having a dump of the NAND is the only cure. Namely flashing to your PSP's flash0 (ie: custom themes).

You should of said you were trying to install a custom firmware on a slim as you need a different memory stick firmware on it. i'll try and find it for you.

[Tyrrell]

So if I put a custom firmware, say 3.60m33, in the root directory of the MS it will upgrade to that FW? will I have to keep the official 1.50 FW in the root directory as well to allow the program to downgrade to 1.50 before it is upgraded to the custom FW

[The EX]

No, it can only downgrade/upgrade you to an official firmware, as it has to extract the files from an update.pbp.

Thanks to all who helped finally sorted through every thread I could and am now running 3.71 M33. I didn't realise I needed to run the despertar_cementerio program on the PSP before I could install the CFW on my PSP Slim.

To play homebrew I have to now install the add-ons (ie the FW 1.5 add-on by DAX)? Will my DGEN and SNES emulators still work on the slim?
