[spoiler]Breaking news on the PS3 homebrew front. The guys at PS3 News have reversed the PS3 Flash ECC Algorithm. That's right, there's progress in PS3 development land.

But first, a small technical explanation. They weren't able to modify any data on the flash chips due to the ECC, which essentially makes sure that data aren't changed or corrupted in the block. If the ECC does detect such action, it then results into error. So modifying anything would be futile at best because then the system would not boot.

What they did successfully do, however, is to use the PS3 to write data to the flush, dump it with the right ECC, and the rewrite it where needed. It's a slow and time consuming process, but the payoff is huge.

According to the team, "After multiple tests done by NDT to see what the ECC algorithm was when the block was filled with some magic data, our very own RPS was able to reverse the algorithm! "

What's all the excitement with this? Well for one, it doesn't have to take eons anymore to edit a flash dump, regen the ECC and flash it onto the PS3 so that you can tweak with flash changes. Apart from that, they've also discovered where the encrypted keys are stored for the following: SELF's, PKG's, and BD Pairin, among other things.

More good things are about to come on this bit of PS3 homebrew development action, so do stay tuned for more. We'll be keeping a close eye on this one.[/spoiler]

[spoiler]More promising news in the land of PS3 homebrew. A hacker known as StreetSkaterFU has managed to partially dump the RAM on a retail PS3 machine, something that could eventually lead to encryption key breaking and the like.

So far, there have been no news of any further progress, but this is a promising step towards opening the PS3 more fully to homebrew. Analysis is still being conducted on the dumps, but we'll be sure to report on any further developments.

You can check out a few screenshots of the dumps at the source link. For more on information on other PS3 hacks and exploits, check out the hacks and exploits below.[/spoiler]
