To install the MAC Address Changer, just copy the EBOOT included in the download below and paste it onto psp/game150 (or psp/game). Remeber, this app has only been tested on 3.03 OE-A, so if you don't have that custom firmware yet, we suggest you go get it now. Also, since this requires some HEX editing, you can only use numbers 0-9 and letters A-F to change your MAC address.

Usage

* Run the app and press X to dump the MAC ID.
* Then, grab any hex editor (I use Hex Workshop) and you should see your MAC in hexes at the beggining of the file. Change the MAC to whatever you wish, just don't type in new characters or change anything else except the MAC, because it could brick if you would do so.
* Save the file and run the app again, this time press O and the left trigger to flash the file to the IDStorage.
* Bam, you should have a changed MAC address! If not, well... you will have a nice doorstep.

Please remember to always be careful when installing homebrew. Nobody wants to brick their own PSP. If you have any questions or suggestions, just head on over to the QJ forums.
