"The concept of creating a custom firmware package that will allow the best of both worlds above and below the 2.0 mark has been around for a while. Thanks to GameShark that\’s all starting to change. He has created the first "custom" firmware package that has all the abilities of a 1.50 PSP, but has the added media capabilities and codecs of 2.0+

Features:
1.5 – Full HB
2.0 Media Fetures

This is a Beta If there are any problems Just Let me know

I hope to add 2.0 UMD support to the next release

Also next release will be pacaged so that it can be added to an existing 1.5"

Right now you need The MPH FW Launcher

Custom 1.5 firmware media edition: [Download Here]

 

So for those that are confused, what this does is that it allows you to run firmware 1.5 with firmware 2.0 capabilities. (wallpaper switcher, internet browser etc) Still in it\’s beta stages, there are more updates to come. AND DO NOT USE THIS AS A 1.5 UPDATE! USE AT YOUR OWN RISK!
