From ReadMe: PS3 NAND FLOW REBUILDER v3.50 (including ECC Algo by RPS).
This tool allows to unscramble the blocks of a PS3 dumps ordering them in a way that the dumps become readable and extractable!
It also allow you to re-scramble back to the original order once you modified the data you wants, then from now on it include the ECC recalculation algorithm that was private until today.
It's for study and tests purposes, for experienced people only (devs) that this way can manage the files inside the flashes and patch sensible areas.
Well this week we have some exciting news that we hinted about last week.
First, a small technical explanation. We were not able to modify any data on the PS3's flash chips due to the ECC. The ECC is a checksum basically, that ensures whatever data is in the block is not changed or corrupted, and if it is it errors.
So, the problem was since when we tried to alter data, the ECC would then in turn be invalid, causing errors, making the system not boot.
We did develop a way around this, however, it was time consuming and quite slow. We used the PS3 to write data to the flash, then dump it, with its proper ECC, then rewrite to where we needed it. This would take hours on end! We were not able to regenerate the ECC since we did not know the proper algorithm.
But now, we can!!
After multiple tests done by NDT to see what the ECC... More »
This tool, although in beta stage, allows you to unscramble the blocks of a PS3 dumps moving them in a way that the dumps become readable and extractable!
It's for study and tests purposes, for experienced people only (devs) that this way can manage the files inside the flashes.
As example I included my PS3 dump map, it should help you understanding the dump layout.
I decided to share the tool early because it need a lot of testing, so, since I'll be in vacation in a few days I thought it would be nice to allow people to begin looking at it meanwhile I return home.
I tested it on like 10 dumps and I noticed that it perfectly worked only on 4 dumps (one was a Debug dump so yes, it works on debug dumps too :), this happen because of the fact I noticed I have to implement another variable in the unscrambling al... More »
Microsoft and Yahoo were pushed to the brink of a multibillion-dollar marriage and then to a sudden breakup this weekend by the same player. It was Google, in the odd dual role of both unwitting matchmaker and self-interested spoiler.
Google’s phenomenal rise, after all, prodded Microsoft, the dominant technology company for more than two decades, to court Yahoo. And Google’s success also weakened Yahoo enough to give Microsoft the sense that it could buy the company at a good price.
A combined Microsoft-Yahoo would create a powerful competitor, and Google early on indicated that it would fight the merger on antitrust grounds in Washington and Brussels.
But Google played a part in killing the deal, for now at least, by acting more as friend than foe. It offered to let Yahoo use its more sophisticated search advertising technology, which by some estimates would have meant $1 billion in additional cash flow a year for Yahoo. The partnership wou...

* Added alot of Rics FAMEC code and optimisations. (Gave some speed increase)
* Altered Hsync handler. (Removes slow down when sprites on screen, with CPU = MAX)
* Altered CPU CYCLE UNIT to 256 (Gave the most speed increase)
* Altered CHIPSET settings (To fall inline with CPU CYCLE UNIT change, its now a
much more finer setting than in previous versions. Giving better results)
* Added Rics FAMEC Sound code (Still clicks, we know what the problem is, but i need
help to solve it)
* Added Interpolation 4CH Sound under sound menu (This can improve sound slighty)
* Altered HEAP SIZE for available memory to PSPUAE (This solves all memory problems)
* A... More »
YOU might think it a bad idea for trainee surgeons to play games on the Nintendo Wii when they should be studying, but it might be time well spent.
Kanav Kahol and Marshall Smith of the Banner Good Samaritan Medical Center in Phoenix, Arizona, have found that surgical residents performed better during simulated surgery after playing on the Wii console. They put it down to the console's novel "Wiimote" control system, which allows players to direct on-screen action using a wireless wand that detects acceleration in three dimensions.
Now they are designing Wii software that will accurately simulate surgical procedures. A training platform based on the console, which costs about $250, might be more practical for trainee surgeons in the developing world than traditional virtual training tools, which typically cost a great deal more.
To test how the Wii affected surgical skill, the researchers asked eight trainee doctors to play it for an hour before p... More »
Dark_AleX has examined PSP firmware v3.80 changes, and here are the results:
They now know that with Pandora, we can always access the flash, so they've focused on locking down the PSAR and changing the format of the files/flash. Just more tactics to slow down decryption, but it won't work.
They have only changed the keys of the tables of filenames. The prx's keys are the same than in 3.7X.
However, there is a little surprise in a form of new compression algorithm called KL4E, this time sysmem and loadcore are also compressed. Plus... again new nids.
So it would seem as if the newly-released PSP firmware v3.80 has already been dumped and decrypted. Only time will tell is Alex will release an update to M33 CFW or make users wait longer.
3.80 module list and decryption info below:
Only a example, the offsets for show another version in 3.71 are:
Australian researcher is on the road to riches after discovering a way to make broadband connections up to 100 times faster.
University of Melbourne research fellow Dr John Papandriopoulos is in the throes of moving to Silicon Valley after developing an algorithm to reduce the electromagnetic interference that slows down ADSL connections.
Most ADSL services around the world are effectively limited to speeds between 1 to 20Mbps, but if Dr Papandriopoulos's technology is successfully commercialised that speed ceiling would be closer to 100Mbps.
