bon on semble enfin y être, le 2.0 hacké
 

Citation :

Update: This proof of concept has now been confirmed as a working exploit for the 2.0 firmware. Now we have to wait until some more useful code using this exploit is released  Remember who had it first PSP-Hacks.com
 
We just received a very convincing email claiming to have hacked the 2.0 firmware. We do not currently have a 2.0 PSP accessible right now. So we would like our members to try it out and let us know how it goes. We’ve been hearing rants for a while about no 2.0 news so here is a chance to not just complain but actually help out and let us know if it works.
 
Digg this story!
 
First Homebrew Code on 2.00
 
—————————–
 
1. Set wallpaper to frame_buffer.png (without overflow.tif present
 
in the PHOTO directory, or it will crash).
 
2. Add overflow.tif to the PHOTO directory, and open into the photo
 
viewer. Custom code to paint the screen! Or to write a homebrew
 
app! Not to run illegal games.
 
How It Works?
 
—————
 
1. The PNG contains a small amount of code in a known, fixed place
 
(the VRAM). If to look closely at the wallpaper, sees small
 
coloured pixels in the right down. The pixels are Allegrex
 
opcodes, with the highest byte all zero for the ALPHA. These
 
pixels do:
 
syscall 0×20C7 ; sceKernelDcacheWritebackInvalidateAll
 
slt a0, zero, sp ; put 1 into a0
 
sll a0, a0, 6 ; put 64 into a0
 
addiu a0, sp, a0 ; get screen painter address over SP
 
jr a0 ; jump to the screen painter
 
nop ; branch delay slot
 
2. The TIFF contains also some code and a buffer to trigger the
 
known BitsPerSample overflow in libtiff in the photo viewer.
 
The buffer makes a jump to the VRAM which has the PNG colours
 
by overwriting the safed ra (return address) on the stack.
 
The VRAM code uses SP and calculates the address of the buffer
 
then runs it. Then it jumps there. The screen is yellow as
 
the colour was 0×12345678 in Hex.
 
PSP Users:
 
We didn’t do this so you could steal from Sony and game companies.
 
We believe in OSS. There are plenty of amazing programs that have  
 
been written for the PSP. Use this as a gift and not as an excuse  
 
to steal.
 
Sony:
 
If you wanted to find us i know you could. This release wasn’t  
 
intended as a way to run pirated software on the PSP. We believe  
 
that everyone should be able to compile their own code and run it.
 
Nothing is kept secret forever and i’m sure you know this.  
 
In the end, if it wasn’t us. It would be some one else.  
 
Fighting it would be like skating up a hill. You did create the
 
PSP and did an amazing job.
 
Toc2rta:
 
To the people of the Toc2rta development network. You’re our phone
 
a friend. With out your friendship this would never of happened.  
 
I hope this brings you as much happiness as it brings us.  
 
Join us on irc.toc2rta.com.
 
Most importantly… Have fun!

Binary Loader v0.2 for PSP Firmware 2.0
 
http://pspupdates.qj.net/DSC02262.JPG
 
The creator(s) of the 2.0 Buffer Overflow have spoken with me and have created a way to allow the execution of a binary file from the root directory of the memory stick. I was told that it will load binary files up to 64k from the memory stick, but won’t load un-encrypted elf files yet. The file named ‘h.bin’ must be placed in the root directory of ms0: for it to run. Here’s what was said in the readme: “
 
Pure binary loader.
 
* it's loaded at 0x08810000
* it's max 64 kb
* it's pure binary MIPS code
* you have to use syscalls and not NIDs
* it runs in user space!
* it's called h.bin (paint screen blue yay!) in the root of the MemoryStick
 
Set the frame_buffer.png as background like before and Place the new overflow.tif in the photos dir and the h.bin on the memory stick. It loads ms0:/h.bin
 
I'm pleased to announce that pspupdates.com will now be joining us as part of the toc2rta irc family. This will happen over the next few days and i'm sure you will see a post on pspupdates about it. Thank you all for your support. Join us at irc.toc2rta.com, channels #pspchat, #pspcaliber and #pspupdates.”
 
You can get it in our PSP Download section [here].
You can discuss it in our forums [here].
 
Thanks for this great progress guys, and developers everywhere!

Le premier code permettant d'afficher "Hello World" ("Bonjour le Monde" ) sur les PSPs equipées du firmware 2.0 est proposé depuis aujourd'hui par groepaz. C'est une avancée significative vers l'arrivée des homebrews sur PSPs 2.0 bien qu'il reste encore du travail à faire.
 
2.0 Hello World ?!
 
Using their previous 2.0 h.bin loader team toc2rta has just released a 2.0 "hello world"
 
This program causes the words "Hello World By groepaz (toc2rta) appear at the top left of the menu.
 
http://www.bat420.com/psp_hello.jpg
 
Interestingly the program was written in C then the produced assembler was edited to allow the program to run.

La lumière sur l'affaire Yoshihiro/Downgrader (par AloneTrio, membre de la WAB Team)
 

Citation :

WAB is DEAD, Enjoy WAB
 
Since the begining of the team wab birth i am lazy to read rumours, shity forum, receive shity mail, etc... so i decided to post a little and terminal wab history.
 
i got my first PSP near JUNE 2005 ( friendly offer by Snkorea and fx0day )
 
i started to code, and i was very happy to discover a new console, without any documentation, with a little compiler hacked from the ps2dev one ( thanks loser )
 
i coded and released some oldschool demo effects ( unlimited sprites, full screen hard scroll, etc...) always released with sources code.
 
Then with Fx0day we released the first psp multipart intro called "killing psp"
Then i coded another intro called "oldskool" under the name of AloneTrio. Lot of people were happy to see that i released sources too and start to code too from this sources.i was very productive in the ps2dev forum and irc chan.
 
i coded another "like-"trainer intro, that was a intro simulating a trainer for puzzle bobble. At this moment lot a forum starting to talk about alonetrio and it's no working trainer, etc... i never said it was a working one, just an intro.
 
So i had idea to code a "mega" demo with some screen from different team wanting participate to this demo "like old time demo days". To do that i needed to code a main menu using a routs capable of launching elf from differents screen team. I quickly coded this rout using a Bri3d tips. And the idea to try launching an official commercial eboot came. and Surprise worked !!!!
So i released the FIRST LAUNCHER under the name of wab "WAB ms Launcher" with source code.
 
At this moment near all psp web site starting to talk about WAB team and the famous ms launcher. and Wab was a real respected "team" ( alonetrio and fx0day ). We received lot of email asking us about joining WAB. And WAB meet yoshihiro...
 
Yoshihiro LOOKED LIKE very friendly and a very good coder. Providing nice new idea for the next launcher. So we decided to make him a WAB member. Yoshihiro started to release some great tools for the psp under the WAB name. I found a new job in paris and i leave the psp coding scene but always looking about yoshihiro's work. Trying to give you some news about it. Before this new job, i was jobless and going to paris is a little expensive. i saw my web stats growing so i decided to make a paypal donation account, to permit people who liked my intro, launcher, sources nice to make a DONATION for the ALREADY DONE WORK.
 
At the same time, talking with yoshihiro using msn make us ( fx0day and me ) very surprise about some yoshihiro's noobs coding question, but even if this questions were no sense, he released tools, etc.. so we didn't take care about them.But we were also surprise to see same kind of tools or functionality some day after WAB from other people.
 
Then yoshihiro starting to talk me about a methode to DOWNGRADE the psp firmware even the 2.0. I was very enthousiast about it. Asking for detail and technics. First he told me about a game sharing trick. Then some day after talking about a swap method. I also saw the psp-dev team association to this project. So even if i was far from the scene i was happy to know and WRITE NEWS on the WAB site about it. He was happy to talk about it in lot of forum, post me some video links, etc... ( same fake video link i posted on wab site ) sorry for this but when the info come from someone of your team you beleive it.
 
I saw WAB website stats growing and growing each days, and lot of people asking by thousands mail " WHEN WILL THE DOWNGRADER WILL BE RELEASE ?". and more and more paypal donation thinking it was for the downgrader. So yoshihiro with the help of pspupdates.com, make a big fake news saying that 1.52 and 2.0 JAP / US was now downgradable and need some paypal to buy a 2.0 EU, permiting yoshihiro to code and test a EU version of the downgrader.
 
I continued to ask yoshihiro about a release date without anymore information.Then last week the wab server hard drive break down, and i bought a new hd yesterday. I learn on different web site that wab was disolved, even if it is not my decision, i approve it ;).
 
FROM NOW WAB IS COMPOSED ONLY BY (Snkorea, Fx0day and AloneTrio). YOSHIHIRO IS NO MORE A WAB MEMBER AND WONT BE ANYMORE. WAB IS NOW, LIKE AT START, A PSP DEMO CREW ONLY. IF YOU ARE MOTIVATE AND CODER WANTING CODE DEMO OR LITTLE GAME FOR PSP, DO SOME GRAPHIC LOGO, DO SOME SOUND AND MUSIC. FEEL FREE TO CONTACT ME AT ALONETRIO AT WAB DOT COM.
 
END OF STORY
 
MY personal feeling about yoshihiro:
like i can read on forums, i thing yoshihiro is not a real coder, he was always at the right place at the right time, i mean he take lot of it's code and idea from others and just mix it all. For sceptic people, just go catch yoshihiro then ask him some simple coding question like "what is a XOR exactly ?" or "what is the diference between compiling and linking ? " you think i am joking ? just ask him.
 
And if you want some info about the FAMOUS YOSHIHIRO DOWNGRADER mail him at:bebedamour06600@aol.com ( it is also it's msn add )
 
See you all soon in the next WAB production.
 
AloneTrio

Scrolling Starfield for 2.0 PSP
 
http://pspupdates.qj.net/DSC02275.JPG
 
Andy Fung, the developer of DJSP/PSPAdvance, has emailed us his creation inspired by the original 2.0 exploit by Groepaz/Team Hitmen, a scrolling starfield demo. Here is what he said in the readme:
 
    Based on the original 2.0 exploit code. I just love star fields. I blame it on the old qbasic days.
 
    Written by me: Lok Tai (Andy) Fung da DJSP/PSPAdvance guy. Email: Cooleyandy[at]hotmail[dot]com
 
    source is included for all you dev folks. I did this for fun. Absolutely no use whatsoever.
 
    It was interesting writing this program when I don't even have a 2.0 yet. I had to scour the irc channels
    for someone to help. Thanks FlongP.
 
    Shameless plug: PSPAdvance Coming soon.
 
    And thanks again to Groepaz/Hitman for the exploit code.
 
You can get it from our PSP Download section [here].
 
Notice:
Also, Andy wants to encourage every dev to start writing code for 2.0. It is very easy, took him only 10 mins to write this demo. Maybe the future is just around the corner now.
 
Thanks to Andy Fung for the email and the cool demo. :)
 
Update
 
And as a respond to Andy & Garman111, PurePwnage has emailed us his mod of Andy's work with different text display.
 
You can get it from our PSP Download section [here].
 
Thanks to PurePwnage for the mod and the email!!

Le chemin qu'il reste à parcourir avant les homebrew 2.0 :
 
Finally has happened. Next steps ?  
 
Well, for right now only MIPS machine code seems to be working, but there's nothing stopping someone from makeing a homebrew loader in assembler...
 
While it is correct that unsigned code is now running on 2.00 PSPs. However the code is running in USER mode not KERNEL mode.
 
For those who don't know what this means, code that runs in kernel mode (i.e. the PSP OS/firmware) is protected by the PSP hardware (CPU). Code running in user mode (games, apps) cannot access memory used by the kernel.
 
This means that at the moment, unsigned code can only access things that games/apps can access, such as the screen output, sound output and button/d-pad input. Unsigned code can only be run in the area of memory exploited by the buffer overflow (64Kb). In order to allocate enough RAM to run proper homebrew (e.g. emulators) kernel access is required. Only kernel code can allocate memory to user processes (homebrew). This is where we are at the moment. In order to get a fully exploited system, the kernel needs to be attacked. Then the PSP will be under total control of the homebrew code.
 
There are different layers of protection between user mode and kernel mode. Think of it as an onion where kernel mode is the core and user mode is the outer layer. As you remove the layers and move up privilige levels, you get closer to the kernel. You can make system calls in user mode which instruct the kernel to do various things but these calls are always controlled by the kernel and are not easy to exploit. By using system calls, it is possible to increase your privilige level and get closer to the kernel (peeling the layers from the onion). This will however take time and a lot more hardcore hacking to achieve.
