Just over a month ago an open-source PlayStation 3 Toolchain was announced, and today AerialX tweeted (linked above) news that he has started an open-source PS3 SDK named PSL1GHT for homebrew developers along with sharing a Kammy PSL1GHT Port.
Kammy is a system for loading patches to lv2 (PlayStation 3's Game OS) from a user application, using PSGroove or any other implementation of the exploit that adds the peek/poke syscalls.
This news comes not long after the recent PS3 SDK 1.92 and PS3 SDK 3.41 Sony leaks, and below are some further details from the ReadMe file, as follows:
PSL1GHT is a lightweight PlayStation 3 homebrew SDK, provided as a temporary way to compile user apps to run from the XMB using the open-source PS3 toolchains available.
A GCC toolchain that supports the PowerPC 64bit architecture is required to build PSL1GHT and its samples. This (http://www.bsc.es/plantillaH.php?cat_id=579) is the only toolchain that I test with and can guarantee support for. PS3Chain (http://github.com/HACKERCHANNEL/ps3chain) probably works just as well, as should marcan's AsbestOS (http://git.marcansoft.com/?p=asbestos.git) toolchain. Some toolchains will probably already use newlib, and will make the included newlib unnecessary.
Run make install in the psl1ght directory to build it all, and make sure to set the environment variable $PSL1GHT to the folder where you wish to install it to, for example...
... for a local build of it. Ensure that $PSL1GHT is set when you are building any of the examples or other apps that use PSL1GHT.
At the moment, PSL1GHT has basic libc support, with stdout debugging, file access, etc. You can call lv2 syscalls and do some fun stuff with that, but it doesn't link to PS3 dynamic libraries yet which is where all the exciting functionality comes in. Also, a make_fself equivalent is still missing.

This means no more pirating Sony's SDK. A good thing always. Now what's needed is free documentation as opposed to copying Sony's CHM. Don't know if this supports everything up to 3.41, but I'm sure you can make most of what you would need to with this.
nVidia didn't make Cg open source ever, so on Linux it's a binary package but you will get the headers, which you'll need to do any advanced 3D stuff. And learn some Cg whilst at it (as opposed to GLSL, it's not very different).
Could you make a homebrew app, that is similar to the FTP server, but something that can work without a blu-ray drive?
That would be awesome! as I cant seem to get any homebrew apps to work, keep getting a black screen after I start any app. And I have tried everything that I can think of. So that is what im trying to figure out, if someone can create what I asked above and I would be very happy to test it.
