Tutorial: How to boot FW 1.5 from your memory stick

One thing has led to another. Noobz and Team C+D’s Pandora’s Battery has opened a lot of doors for the PSP homebrew scene and it would seem that the possibilities are near endless. Flamingwolf from our forums posted a guide to running the golden firmware, 1.5, from the memory stick.

It is possible to boot firmware 1.5 from your memory stick and you’ll find this nifty guide very helpful. The guide was originally written by Mathieulh. Need we say more?

One thing has led to another. Noobz and Team C+D’s Pandora’s Battery has opened a lot of doors for the PSP homebrew scene and it would seem that the possibilities are near endless. Flamingwolf from our forums posted a guide to running the golden firmware, 1.5, from the memory stick.

It is possible to boot firmware 1.5 from your memory stick and you’ll find this nifty guide very helpful. The guide was originally written by Mathieulh. Need we say more? Here’s the post ad verbatim:

• Install the pandora firmware to the memory stick using the normal procedure.
• Copy the files created on the memory stick somewhere on your computer
• save your flash1 registry folder into your memory stick root
• Extract 1.50 from a psar using psardumper.
• extract it as encrypted and then once more as decrypted (save both dumps)
• Copy the encrypted dump folders to the root of the MS, and get pspbtcnf.txt pspbtcnf_game.txt and pspbtcnf_updater.txt from the decrypted dump, and use those to replace the ones from the encrypted dump located at ms0:/kd/
• Get the flashemu.prx and lfatfs_patched.prx from the pandora MS files you saved earlier (they are in the kd folder) and copy those into ms0:/kd/
• open ms0:/kd/pspbtcnf.txt and ms0:/kd/pspbtcnf_game.txt and ms0:/kd/pspbtcnf_updater.txt files using a text editor and:
• change /kd/lfatfs.prx to /kd/lfatfs_patched.prx
• add /kd/flashemu.prx right after the /kd/fatmsmod.prx line.
• save the files

• Done, the 1.50 firmware will boot straight from the MS using the Pandora battery. Of course you may adapt this mod to another firmware such as M33.

Using Mathieulh’s guide, you can basically boot any FW from your memory stick/s – that’s in theory. If they find out how to do this with other FWs then it would be great for homebrew devs who want to test how their creations fare on different firmwares.

Though for now, we’ll heed what Dark_AleX says about booting from the memory stick and custom firmwares. He said, “No CFW will work with this, because their kernel subset would need also a flashemu.prx. This method would only work to boot 1.50 from ms.”

Well, let’s hope for the best anyway. For more info, feel free to scurry over to the QJ PSP Hacks forums to discuss the tutorial.
