if you want an ultimate psp your best off using the safest downgrade method the "Noobz" 2.00\01 downgrader, then once downgraded look in to the Dark_alex 3.03oe-a custom firmware + oe-b update, once you install the 3.03oe-b you can use all the latest feature including the bonus of homemade ps1 game emulation full screen (480x272) avc movie files Backup loading from memstick (no loaders required), note location free-player and korean font have been removed, the 3.03oe-a includes the feature from 3.03 fw like 8gb+ memstick support, web browser, custom backgrounds, camera etc. as well with a bit of magic you can fully customise the xmb icons the system version and much more, as well as having a recovery mode if you have any mishaps while making your psp "yours".
