PSGroove Released, Open Source PS Jailbreak

by Mike Bendel on August 31, 2010 @ 9:34 pm

True to their word, Mathieulh and the crew have released a open-source implementation of the PS Jailbreak exploit, coined PSGroove. The software is compatible with AT90USB and related microcontrollers. Grab a Teensy USB development board and you’ll be all set.

It’s worth noting that the PS Groove code is not a 1:1 copy of PS Jailbreak’s take, as it lacks support for running backups. The software is intended only to allow the execution of legal, third-party homebrew applications. To top it off, this rendition of the hack nixes references to the LV1 panic hypercall, meaning you are free to remove the dongle after installation.

Check out the PS Groove code repository here.

YEAHHHHHHHH! HELL YEAH! AMAZINGLY NICE DONE, GUYS!!!

[/capslock]

So, now, time to port it to the PSP being the "dongle".... who's in? :D

KezraPlanes says:

I think you have more important things to do.

*cough* CD *cough*

xD

keyblayder says:

Great news indeed.Im happy that they will not release the backup stuff.Thank you Mathieulh and the rest of the team that they helped!Time for some PS3 Homebrew apps.

Hellcat says:

@Kezra:

Yeah, you are totally right! Hence me not seeing myself actually working on it - unless something else (said "CD") starts working all of sudden xD (but I have the feeling I am close)

KezraPlanes says:

'bout time :D

RoBz says:

awesome stuff

Muratcan says:

All it took was a 4 ASCII hex edit and backups are now playable xD

Awesome news, and on the 5th year anniversary of the PSP's release here in Europe!

Math also said something on Twitter about the dongle not being needed? :S I quote Matheiulh:

"The psgroove for now allows the very same features as the psjailbreak but without backup manager support, you can also now remove the dongle

The original psjailbreak dongle had a patch that would trigger the lv1 panic hypercall if the dongle wasn't in the list of connected devices"

RoBz says:

He means after you run exploit once you don't need to constantly have the dongle in...I think.

Muratcan says:

You mean like if me and my friends bring money together to buy a TEENSY (or equivelant), then we can each hack our PS3s and be done with it? :S I doubt that though.

RoBz says:

Thats what I gathered from it yeah...hmm

KezraPlanes says:

What he means is that you only need the dongle to boot the exploit each time. PSJAilbreak forces you to have it plugged in at all times, and Groove only needs the dongle once each time you boot your PS3.

El Diablo says:

Zomg someone buy me one of these teensy boards :(.

Hendo420 says:

Do I have to use a Teensy ++ board or can i just use Teensy 2.0? Cause i think there sold out of the Teensy ++, i bought a Teensy 2.0 so hopeing your precombiled hex will work on it. ^.^

ChurchedAtheist says:

really? what line was changed?

keyblayder says:

You can use both of Teensy++ and Teensy 2.0 dongles.Actually you can use Teensy 1.0 Teensy++ 1.0 Teensy 2.0 and Teensy++ 2.0.Once you have compiled the .hex files to make psgroove.hex you are ready to go.Hope this helped you.

El Diablo says:

Ps3hax has a pre compiled version tht supports the bxkup maager on their front page.

Muratcan says:

The "Descriptor.h" file had a line XXXX which when changed to bdvd enables backups to work.

driafrai says:

Buy AT90USBKEY from [tinyurl.com]

Riorio99 says:

I was hoping that this would be done, but I can all but guarantee that it will be hacked/modified for back-ups fairly swiftly.

Muratcan says:

It already has. It HAD the backup option from the beginning, it was just a 4 digit HEX change that made it not work. Someone figured it out and now a version with backup launching is floating around.

El Diablo says:

It already has.

x3sphere says:

The pre-patched version is linked in the original article, I added it last night.

Also, lan.st's PS3Wiki has been updated with loads of details on how this hack actually works. Interesting stuff:

http://ps3wiki.lan.st/index.php?title=PSJailbreak_Exploit_Reverse_Engineering

EndymionDave says:

watch the ps3 sales soar high he he he, higher than it already attained.

Riorio99 says:

I think i'll wait until a) we see if Sony slams the banhammer, and b) see if any decent Homebrew comes through.

Distrance says:

Soo .. Just wanting to confirm this before I go out on my way and buy a teensy or the other alternative.

First off, does it actually matter wether I use teensy or the AT90USBKEY ? The latter would be available in my country, and all teensy boards are out of stock.. no surprise there.

Secondly, if using the pre-patched version with the manager file downloaded on the usb stick, I will be able to backup my games and then play them off the harddrive without actually having the game in drive ? ( As long as there is some dvd )

Thanks if anyone can answer.

x3sphere says:

Either the Teensy or AT90USBKEY will get the job done, there's no notable difference between the two. The code is being ported to other devices as well, I heard one team is working on USB driver for the PSP. ;) Might be awhile before we see it, though.

And yes, you are correct in regards to running backups. I will write up a guide soon, just waiting on my Teensy shipment. Should get here in a few days.

El Diablo says:

As matheiueghgh (whatever his name is) said, the program disables PSN so there's no way of getting banned.

Now to decide if I should buy an external hard drive since my old one died, or a replacement internal one for my PS3. External is so much more functional but not being able to use a lot of games blows = \.

vXAlexanderXv says:

So by using this there is a chance of gettng banned from the PSN? Or is that only if your playig backed up games?

x3sphere says:

No one knows yet. Microsoft bans in waves and it's possible Sony may take a similar approach.

To err towards the safe side, I'd recommend not connecting to PSN with the jailbreak enabled at all. Even if you aren't running backups. There's no telling what sort of data Sony collects on your console right now. Best to wait until more research is done.

vXAlexanderXv says:

Indeed. I can only hope emulators are of the first homebrew to show up. I'd love to play some SNES or GBA games wth a wireless controller. :D

ChurchedAtheist says:

I assume this will work?

january39 says:

That's my fear, no access to PSN would be a real drag....although i could set up another account and get another ps3 ;) Im going to wait before i buy though and see what pans out over the next couple of weeks.

I will not be updating past 3.41 in the near future though.

It reminds me of the early early days of PSP :) :)

It is interesting, i lose it a bit on the more technical stuff but i get the basic theory.

El Diablo says:

Assuming you can even download a ps3 game from anywhere, how are you supposed to get it on your ps3 anyway? If you can't put files larger than 4 gigs on an external hard drive that the ps3 can read how are you going to transfer them to your ps3?

x3sphere says:

AFAIK backups are run as an extracted ISO, not as a flat file. Majority of games don't have a single file over 4GB in size. So it's a non-issue, for the most part. Granted there are a few exceptions but most likely someone will find a way around the FAT32 limitation.

El Diablo says:

Yeah I know most don't but there's still quite a few that do which sucks. I was mainly wondering because I saw one ps3 game on a website and it was listed as a 7 gig iso or what have you so I assumed trying to transfer that 7 gig file wouldn't work.

All I can say is I hope a PSP version is possible and made soon. Not because I want to pirate but because I'm poor and could really use the money from selling all my games I don't need anymore heh.

Adiuvo says:

It's a bit disappointing to see ISO loading enabled already. I'm interested in the homebrew that will come out of it (especially emulators), but the pirating side isn't too great.

El Diablo says:

I'm definitely more interested in the homebrew, but being able to save my expensive games and try and get some money back will be nice :p.

Hellcat says:

No, you need the dongle on every reboot/powerup.

But once the PS3 is full booted up, you can unplug it and use the now free again USB port to charge the controller.... O:-)

The original PSJB needed to be plugged in all the time.

thatsnice says:

You get a copy of the game and put it in the PS3, then back it up to your internal or external HDD. There is no need to download a PS3 game from the internet. Just rent or borrow a friends copy of a game.

Any word on running this off a PSP yet?

Zero says:

Don't know how well homebrew will take off with the Cell's multithreaded architecture.

Although once a few decent emulators pop up, i'm going to be all over this.

BlackSheep says:

Would it be possible to have a xbox emu?

or even a xbox360 one?

Adiuvo says:

No. The 360 and PS3 are too close together power wise.

BlackSheep says:

how about a wii? With the move i assume it will be possible

El Diablo says:

Seeing as how Wii emulators for PCs aren't 100% I can't see there being one for the ps3.

At least not one that works any better than Daedalus for psp.

x3sphere says:

Possible yes, full speed is another story however.

Hardrive says:

So... is it possible to write homebrew for this yet?

And why the hell does everything have to be called a Jailbreak now? What happened to the word "exploit"? Get off my lawn...

Hellcat says:

In theory homebrew is possible, yes.

BUT: There is no free SDK like for the PSP, you'd need to find the SCE SDK.... not only is that a very hard task but HB created with that is automatically illegal since the author never had the right to have and use that SDK....

ChurchedAtheist says:

couldnt a large group legally purchase a copy? start a exophase studios perhaps, and any dev who joins has access. this is probably not allowed,but im not sure what the sdk rules and restricions are.

Adiuvo says:

By doing that I'm sure you would have to go through Sony to get your things released, not just prop them up on the internet.

yolarrydabomb says:

If I had a PS3...this will be great for my psp since I dont use hardly once in a blue moon.

El Diablo says:

Does anyone know if there's any sites that list what games are able to be ripped to an external hard drive and which have files over 4 gigs and can't?

ChurchedAtheist says:

dont imagine any do.

although, if having files over 4gb is all that is required to break this, within 6 months expect every game to have a 4.1gb file that is critical.

El Diablo says:

Yeah that's what I was thinking as well, although maybe as more stuff comes out for this maybe eventually a CFW will come that will let you not be forced to use fat32 to get around the 4 gig thing.

Saw this on ps3hax.net today

Really praying NTFS support comes around.

Sousanator says:

Wow, just having mkv (and other video codec possibilities) makes the $30 for a Teensy board worth it

Hardrive says:

Is ps3hax reputable at all though? They didn't used to be.

El Diablo says:

Well all the information was from another website, I just saw it posted on there /shrug.

x3sphere says:

I wouldn't put much faith into that list. Why would it be "compatible with all PS3 firmware" when the exploit itself only runs on 3.41 o_O Fishy I'd say..

El Diablo says:

The exploit runs on anything up to 3.41, no?

x3sphere says:

Only works on 3.41 as far as I know. The RAM patches are specific to that firmware.

Distrance says:

If it only works on 3.41, but I haven't updated my PS3 in the ages, does this mean I can't use this ? Or is the current version available 3.41 ? Meaning I should update right away ?

If it isn't, and I dont have 3.41, how to get 3.41 ?

x3sphere says:

Downloading 3.41 through Network Update should still be safe, Sony has never issued a stealth patch before. However - if you want to update manually, we have a copy of the firmware hosted here:

http://downloads.exophase.com/685/ps3-firmware-341/

Copy the .PUP file to the UPDATE folder on your USB mass storage device, plug it in, and you'll have the option to "Update via storage media" when clicking on System Update.

El Diablo says:

I'd try it first with whatever FW you have now though. Originally PSJailbreak said it worked on all current FWs so it wouldn't hurt to try before you updated it you had to.

Also, someone came out with the jailbreak for N900s if you have that. http://exophase.com/ps3/psfreedom-released-psgroove-ps3-exploit-ported-to-n900-18008.htm

That site also has a compatibility list for games. http://psx-scene.com/forums/showthread.php?t=65065

Distrance says:

Thanks for the link, I guess I'll do manual patch, just in case, assuming it's completely safe.

As for the Teensy board or the alternative ... To me it looks like a chip you'd see inside a computer or something so I was wondering how to handle these. Ex. can you touch and carry them barehanded or should I get a case for it ? ( from where? )

Why is this available only on those boards ( +n900 ) anyway ? Why won't normal USB stick do the job ?

x3sphere says:

Regular USB sticks are not programmable, it will never work with those. This hack emulates a 6 port USB hub to trigger a heap overflow during the PS3's boot process. Like the N900, the iPhone and Android-based phones are candidates as well.

Carrying the Teensy along the edges should be fine. I'm not an electronics expert, but I doubt it's as delicate as, say, RAM. Still, I'd like to pick up a case for it as well, haven't found anything suitable yet though.

atavist13 says:

Confused bout how to use the teensy, if i do get my hands on a 'Teensy', how do i flash it with the precompiled psgroove.hex file. :|....

x3sphere says:

It's extremely simple. Just use the Teensy Loader app here: http://www.pjrc.com/teensy/loader.html

While you have the device connected via USB, open up the HEX file that corresponds to your board from within the app then select Operations - Program to flash it. After that select Operations - Reboot to finish the process. :)

atavist13 says:

Thanks :)

and what bout the other one, the AT90USBKEY.... i downloaded the dfu programmer but its' a ".spec" file.. never heard of it... i'm extremely new to these things.. :(

I dont' even know if the 'Teensy' board or the AT90USBKEY board will be available in my country...might have to order online... :\

x3sphere says:

There's an app specific to the AT90USBKEY as well, here it is: http://www.atmel.com/dyn/resources/prod_documents/JRE-Flip_Installer-3.4.1.exe

The process is essentially the same, connect via USB while in program mode and load the HEX file. Once the flash instructions are loaded, click the "Erase Target Device Memory" button followed by the "Program Target Device Memory" button.

atavist13 says:

Thank You again... :) Much appreciated.....

Distrance says:

Thanks for the clarification x3sphere. If you do find a suitable case for the board, please do post so I may be able to obtain such or similar one to it as well.

MegaMatX says:

I own a PS3 Phat with firmware version 3.15. Is it possible to keep my Linux and Zerogamer project "EMU" and also install and run the psjailbreak, psbreak usb or ps groove: or do I have to upgrade firmware to 3.41 exactly? I want to use the psbreak usb and also keep my other os option and not to upgrade firmware, is this possible yet? Also are their any rumors of a patch or software for the psgroove, psjailbreak or psbreak to install the other os back onto slim models or to make it possible to keep the other os "Linux" and run the jail break as well??? Game on...

Hellcat says:

The PSGroove is -as of yet- only compatibel with 3.41.

If, and when, it will be ported to other FWs.... no one can tell at the moment.

MegaMatX says:

The FW updates and PSN are all Sony have on PS-Groove, if this last challenge is overcome..we win. After that, home brew is the victor. The fact that these doggles are upgradeable gives me optimism for the future of the console modification scene. I just hope for the best! 4.2 is out and soon 5.o, so I will stick with my 3.15 fw and have some faith that ps groove and the progress made will be enhanced even farther, it can be done. Any info from the ps groove team about making it compatibel with all firmwares and undetectable by sony, please share

MegaMatX says:

Sorry to linger: or how about adding back the other os option and we stick with 3.41 via usb upgrade? Although that would leave out the future stuff sony adds to newer FW. If only we could find a way!! :)

atavist13 says:

Okay is it possible to extract the game first on an external HD after downloading and then copy it to the ps3's internal HD?
