Guide: How to Reconstruct PS3 SELF Files After Decrypting

300°
188w ago - Today netkas (linked above) has shared a brief guide on how to reconstruct PS3 SELF files after decrypting them for PlayStation 3 developers.

To quote: Here is a little, noob-unfriendly howto about recreating ps3 apps after you have decrypted it

as example, I will talk about vsh.self, which everyone on jb ps3 can find in /dev_flash/

1) decrypt it with graf_chokolo's payload, you will get two files after all, lets call them vsh.0 and vsh.1

2) compress these files with zlib, I use zpipe for it ([Register or Login to view links])

cat vsh.0 | ./zpipe > vsh.0z
cat vsh.1 | ./zpipe > vsh.1z

size of files:

6951464 2010-12-05 02:06 vsh.0
2930941 2010-12-05 04:04 vsh.0z
338832 2010-12-05 02:06 vsh.1
133356 2010-12-05 04:04 vsh.1z

3) going into vsh.self
look at 64-bit big endian value at 0x290 - 0x0000000000000900 (2304 decimal), its start of first segment (vsh0) in vsh.self, next 64bit BE value at 0x298 is size of this section - 0x00000000002cb8fd (2930941 decimal) , perfectly matched to size of out vsh.0z
 

Guide: How to Place PS3 Apps into Different XMB Categories

650°
190w ago - Today NZHawk has shared on his blog (linked above) what he calls a little find, specifically how to place PS3 apps into different PlayStation 3 XMB categories.

To quote: "Well I was talking to DarkHacker about param.sfo files and that. He asked me to try changing the CATAGORY string to 'HM' and see what it did.

It made the package install under the PlayStation Network catagory on the XMB. DarkHacker and I then worked out the rest of the catagories that its possible to install and run hombrew applications to the XMB, and found them all except Users, Settings and Friends (which all seem to be filled with the XML files in the VSH flash folder).

String / Category
HM / Playstation Network
CB / Network
HG / Game
AV / Video
AM / Music
AP / Photo
AT / TV

I thought this was quite interesting, and would be great if we could add a Hombrew catagory to the xmb and make all hombrew apps install under it to make some hombrew standard, much like the wii has. (Also has anyone though about making a database of hombrew Title IDs to keep track?)

Oh, and its possible to change this location after install via application settings."

Thanks to PSGroove for the news tip and to Jes03 for posting this a...
 

Guide: How to Use Your PS3 Eye as a Webcam for Windows PC

550°
190w ago - This weekend fl1pp13 has shared a guide on Dutch site PS3-Sense.nl (linked above) on how to use your PS3 Eye from the PlayStation 3 entertainment system as a Webcam for a Windows PC.

Download: PS3Eye Camera Setup v2.1.0.0130 (for the required PS3EyeTest.exe) / CL Eye Driver v4.0.2.1017

To quote, roughly translated: It is now increasingly common for laptops have a built-in webcam. Because of this chat is becoming increasingly popular.

Not everyone has the money for a laptop or an external webcam. But what if you already have the PlayStation Eye? For several months, this one with some special drivers to get working on almost every version of Windows.

The webcam has pretty good specs, but for the experts among us we have a list:

•4 channel audio input:16 bits/channel, 48kHz, SNR 90db - 4 channel audio input: 16 bits / channel, 48kHz, SNR 90dB
•56 or 75 Field of View zoom lens - 56 or 75 Field of View zoom lens
•2.1 F-stop, less than 1% distortion, fixed focus (25cm to 8 at 75 FOV)
•640 x 480 at 60 frames/second - 640 x 480 at 60 frames / second
•320 x 240 at...
 

Guide: How to Compile PSFreedom's Payloads with Ubuntu 10.10

400°
192w ago - Over the weekend Klutsh [Register or Login to view links] a simple guide on how to compile PSFreedom's payloads with Ubuntu 10.10.

He states this is for the payloads only and is independent of devices, and his next guide will cover compiling the kernel and the kernel module which are device dependant.

Below is the guide, to quote:

Here's a real quick guide on getting Ubuntu 10.10 ready to compile the PSFreedom payloads.

Prerequisites:

•A Working install of [Register or Login to view links]

The Guide:

First thing we need to do is install some applications through apt, so open a terminal and do the following:

sudo apt-get install git-core gnupg flex bison gperf libsdl1.2-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev gcc-4.3 cpp-4.3 g++-4.3 texinfo autoconf

Now we need to clone PSFreedom from github to our local PC, pull it's submodules and get the toolchain installed

cd ~/
git clone git://github.com/kakaroto/PSFreedom.git
cd PSFreedom
git submodule update --init
cd pl3
git submodule update --init
cd ps3toolchain
 

Guide to Compile PS3 Homebrew via PSL1GHT Open-Source SDK

550°
192w ago - Today Scognito has [Register or Login to view links] a guide on how to setup a build environment for compiling and running PS3 homebrew using the PSL1GHT open-source SDK.

To quote: With the breaking out of PSJailbreak this summer, the homebrew sceene didn't wait so long to appear on PlayStation 3.

So we are finally talking about the possibility to run our own unsigned code, using any of the available dongles (you can even build one yourself).

Before actually start writing our application it is necessary to build our development envirement. For doing this we need a toolchain and a SDK: I'll use ps3chain and PSL1GHT.

The latter one is very young (project started 29-oct-10) and continously mantained, so the are chances that something may not work as you would expect.

Updating git daily, reporting bugs and contributing is appreciated

Prerequisites

First of all we need to set our PS3 dev directory and some system variables, as well as all software needed to build our toolchain.

This guide is written for user with Ubuntu 10.10 32bit,...
