PSP MAC Address Changer

[Vega]

gracz54 has released a little app to change the MAC address of your PSP.

If you download this, there's only one Eboot around. For the newbies, this means that if you're firmware requires two folders of the application, then you'll have to use PSP brew.

Another thing to be cautious about is that its only been tested on 3.02 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.

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.

[Shrygue]

Hey, it sounds great! I always though it was hardware assigned and couldn't be changed. I'll give this a try...

[Vega]

I havent tried this myself and i know theres a brick risk if done incorrectly so please be careful :)

[Shrygue]

YES! It worked! I now have a different MAC address shown! Thank's for making this Vega!

Oh yes, I have custom firmware 3.03OE-A installed, if you want to know.

[Vega]

I didnt make this, gracz54 coded it. I just posted it up as news :D

Glad it worked though.

[Shrygue]

Oh sorry about that, I went stupid and rushed though the article but still it's all good anyway.

Does this just patch the IDstore? cause it wouldnt change the hardware Mac Address, it would just change the Mac Address you see in System Information

Correct me if I am wrong

This would be usefull for hiding your real mac address, if you intend to record you doing something on the PSP and need to show the screen with the mac address on it

[Vega]

Equin0X, Im really not sure... though I think it simply does just patch over the MAC address which is shown on screen. Again, Im not sure though.

Yeah, there is an internal IP address that is in the WLAN adaptor. This would only really be of use if you changed your WLAN adapter, and needed to change your mac address to match it... It's a dangerous program with little use.

It's a dangerous program with little use.

I was thinking that too, cause it does edit "Flash0" and anything that writes to that can potentially brick a PSP

Yeah, and editing the idstorage is even more dangerous, even UP users can't easily recover from an idstorage brick.

So my advice to anyone: Only use this if you have a use for it... i.e. new wlan adaptor.

to people that dont know, this patch is permanent and not just an overlay on the system info bit. if it was just an overlay X-flash would display your PSPs orriginal MAC, not the new one, wouldnt it

[F9zDark]

I'd think the PSP would be smart enough to get the WLAN adaptor's mac address on its own. It may just store it so doesn't need to look anymore, but I am willing to bet that anyone installing a new WLAN adaptor (if its even possible) could just do "Restore Default Settings" and have the new mac of the new adaptor show up.

-Added--

The MAC address is in the hardware, and physically resides in a place on the network hardware, as is the case with all network hardware. It is my understanding that MAC addresses are unique to every piece of hardware for networking and can never be changed. On first boot, I imagine the PSP gets this MAC address and writes it to flash, which now that file is changed to reflect the new MAC setting. Read above to see what I think would probably restore the original MAC setting (if it doesn't then oh well, but the MAC address on the adaptor cannot be changed at all.

You could still get your official MAC address back if you backed it up previously and reflashed it.

[jak66]

yea i know (i did) but theres bound to be 1 person that wont

I'm afriad restore default settings only clears the flash1 settings... It doesn't touch the idstorage.

i know tyhis mus realy sound a little blond but... beep breath... whats the mac thing for again

[Shrygue]

The MAC address is the hardware identifer for the wi-fi card in your PSP.

[darn02]

thanks, ive been here a while and never caught on lol, i might just go ye my hair blaond now and complete the process

[cloud_952]

o_O So.. when you actually went out to connect to, say, a router with your PSP, would this be working as a spoofed MAC? I could see maybe some uses for that (such as: you've been blocked from using a router, or a router is enabled for only certain MACs, and thus you could match it up to a trusted computer when connecting). But if not.. this is just incredibly dangerous and terribly useless..

[Shrygue]

I edited and flashed the MAC address idstorage key and if you were to look on a router to see what deivces are connected, it shows the official one. So really this application just simply spoofs the real one because I just tested it out twice and my router displayed the PSP official one each time in the connected devices page.

[pt9087]

As said before... This is a well worked on App but yet again not very useful.

[Shrygue]

I find it still good anyway. It's useful if you're recording something (like a upgrader/downgrader video) and you're showing what firmware version you have in it but not wish to show your real MAC address.

[SpooForBrains]

It is, in some instances, possible to change the MAC address of a network adaptor. You can do it with certain adaptors in Linux. Of course, that's not what THIS does, just letting you know that it's possible.

[not here anymore]

question: why on earth would you want to change your MAC addy?
Later,

TSR

[SpooForBrains]

... to gain unauthorised access to a wireless network, for one thing.

[pt9087]

Or if being blocked by a router, if you change then you could get in.

But also someone mentioned that he changed it and on his router it was the same MAC address

[goaliedude]

wow this is great couldn't this be used to run ps1 games with the official emu with repeat lisences because the liscense is linked to ypur mac adress right?

[Cloudhunter]

No. Besides, if you were officially 3.03, how could you run this?

[scottyboynow]

It is good say if you accidently shown your mac address on youtube so you can change it.

[Shrygue]

Here's the result of using the MAC address changer application: It's a bit blurry because my web camera is a bit dodgy but the MAC address displays 00:00:00:00:00:00.

[Vega]

YKB, your mac address shown on screen when using a wlan adopter stll remains the same as it was originally though? im guessing its not 00:00:00 etc ?

[Shrygue]

That is correct. My wireless router still sees the true MAC address of my PSP instead of what's shown on the screen in System Settings. It's because the official MAC is hardcoded in the wi-fi card itself.

[Vega]

I see. Thanks for confirming.

[Shrygue]

Hey, no problem at all. :)

[Squidman]

.....if the MAC is found in the file you edit, would the firmware number ALSO be found in there? or is that another file?

[carlitx]

what is so big bout this is any benifit from using this?

[bullhead]

^^ Its just a little proggy for those fancy people who like to be fancy. Y'know?^^

bull, x.

[carlitx]

o so its just a program for to just cahnge a mac adress that means nothing anyways......or does the mac adress mean something? is it doea what is it purpose?

[bullhead]

"A MAC address, short for Media Access Control address, is a unique code assigned to most forms of networking hardware. The address is permanently assigned to the hardware, so limiting a wireless network's access to hardware -- such as wireless cards -- is a security feature employed by closed wireless networks. But an experienced hacker -- armed with the proper tools -- can still figure out an authorized MAC address, masquerade as a legitimate address and access a closed network."

bull, x.

[scottyboynow]

Which part of the PSP does this write to.

[bullhead]

Flash 0

[xxAndrewXX]

how does it work i cant get it to work

[Art]

Well it is a year old.
It only changed the MAC address shown on the screen, not the
MAC actually sent to routers.
It's probably not working with firmwares later than it was written for.
