gracz54 has released an update for his MAC Address Changer over on the QJ forums. For the uninitiated, gracz54's app changes how your PSP's MAC address appears in the system info menu. It doesn't actually change the MAC address, since that depends on your PSP's built-in Wi-Fi card.

Anyway, here's the changelog for the new version:

• a few bugfixes
• added a few checks
• added 1.5 version
• added proper thanks

To install the MAC Address Changer, just copy the EBOOT included in the download below and paste it onto psp/game150 (or psp/game). Remember, 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 the editing is done in hex, 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 beginning 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 click on the "discuss" link below and talk about this release on the QJ forums.

Coders have been coming up with all these homebrew "changer" apps lately which allow you to, well, change various things in your PSP. We have gracz54's PSP Mac Address Changer, and there's also Aserto's PSX GameID Changer.

And now, to add to that ever-changing list of changer apps, here's another one from Dabomstew which will allow you to change the version displayed in 3.03 OE-A system settings without hexediting or manual flashing.

Usage Instructions:

• Check that your psp is on firmware version 3.03 OE-A by Dark_AleX. If it isn't, you cannot use this app.
• Connect your psp to your pc via usb. Then copy the vc folder supplied to X:PSPGAME150 (where X is the drive letter of your psp).
• Disconnect USB and run the version changer like you would any homebrew app, and follow the onscreen instructions.
  

Additional notes from Dabomstew:

I was able to update 3.02 OE-B to 3.03 OE-A with a custom version on 3.02 OE-B, but im not sure about the updaters to go to a new release on the same kernel eg 3.02 OE-A to 3.02 OE-B. I guess we'll see =P If it doesn't work, you can easily change your version back to default.

He also said that this worked fine on his 3.03 OE-A-donning PSP, but it's not guaranteed that it'll work 100% every time. If you encounter any problems with this app, please drop him a line in our forums so that he can update it but he says not to expect any more functionalities to be added. However, if Dark_AleX will come up with more versions of his custom firmware, he may bump up this app to include support for DAX's updates.

gracz54 from our forums is back, and this time he's got his PSP Mac Address Changer done and ready for sharing. Now, if you download this, there's only one Eboot around. For the newbies, this means that if you're firmware requires two Eboot folders of the application, then you'll have to use PSP brew.

Another thing to be cautious about is that he's only tested this on 3.03 OE-A. For some run-through on the installation, just paste into psp/game150 (or psp/game). And then, run the app and press X to dump the MAC ID. Once you've grabbed a hex editor, you should be able to see your MAC in hexes at the beginning of the file.

This bit is important! You may actually change the MAC to whatever it is you'd want to be, but DO NOT TYPE IN NEW CHARACTERS or change anything else EXCEPT THE MAC. Why? Because it could brick if you do not heed this warning. So just be a good boy and follow directions to the letter.

That way, we'd all have a nice little MAC Address-changing experience.
