Mathieulh posted this guide to Run 1.5 firmware from the MS [Using Pandora]
To do what you want to achieve is very easy.
- 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.
