Today SKFU has posted a brief guide on three way to run your own code on Sony's PS3 console, as follows:
The easiest way to run your own code on the PlayStation 3 is through Linux which you can install as alternative OS. Several restrictions regarding the RSX, but it seems to become better regarding 3D acceleration since the new MESA 3D GL was released with CELL support.
A few days ago I reported, that the developers of demonhades.org found out, that BD-Java still works if you correctly burn it on a Blu-Ray disc. With the FreePlay's minimal BD-Java SDK it's quite ok to develop Java for PS3.
Since FW 2.0 till FW 3.0 there was the so called Informationboard. This is a simple .swf file on the HDD and can be replaced with knightsolidus' HDD decryption method. As the informationboard.swf does not run in a sandbox there's a lot possible but sadly it was removed in the actual FW 3.0.
But what is the point of running a swf outside a sandbox? There ain't much you can do with a swf systemwise, as far as I know. It ain't C, you know...
Anyway, it's still a good compilation of current homebrew methods. Still, not useful for me but, don't get me wrong, I'm not complaining. What I meant to say was that I look forward to the to the day when we will be able to run any code, limitlessly, in the ps3. But still, I'm skeptical that this day will ever come. We will see. Future will tell
