Cell specs -- from slashdot

According to an EETimes article, IBM is planning on releasing the full specifications and software libraries for the powerful processor that will be in the Playstation 3. The goal is to stimulate open-source development for other applications of the chip. The article doesn't mention if there will b...

A weird blob of data that changes once per second. Take that as you will. This is probably part of the crypto handshake. My guess is that it's probably either sending a salt or a block-cypher key, possibly encrypted with its private key (and therefore decryptable by using its public key), in which ...

Although having said that, why are mod chips legal? It depends on where you are. In some places, they're not legal at all. In some places, like the USA, they're not officially illegal, but they're sort of shady -- you won't find them at Best Buy. And in some places they're perfectly legit, and crea...

You should count it as a blessing that Sony has never asked you to change or remove anything. That means you're doing something right and you should keep on doing it. Well said.

Part of the difficulty in supporting the PS2 file system under Linux comes from the fact that the PS2 partitioning system (APA) is different than on standard PC hard disks, so you'll need to add stuff to linux/fs/partitions/ as well as supporting the filesystem itself in linux/fs/pfs. There are weir...

I must say I'm not sure how portable the Java VM is though. Isn't it closed-source? There are numerous open- and semi-open-source Java VMs. The source for Sun's HotSpot VM is one of the better-supported ones (it falls into the semi-open-source category). This is the VM that you get when you get Jav...

The downside of automatic firmware upgrades, is that if we can find a weakness that allows us to do homebrew (e.g., the Independence Day exploit on the PS2), it will be pretty easy for Sony to close it up and distribute it to all the current PSPs that have been sold (as opposed to waiting until anot...

Maybe just change or add a few lines of code to make it compatible ?
Oh, man. Ignorance is bliss, I suppose.

Short answer: porting any game to the PS2 using the homebrew tools and libs is an extraordinary amount of work.

From the very few fragments of 'official' code that I've seen, I'd say that if there's any compatibility anywhere, it's more of a coincidence than anything else.
