Going a little off topic.
I found the PS2 Linux kit very awesome tool when you realize what it's used for. I got rid of mine for reasons other than political.
Yes, you are not going to be able top make games for others to play. Not only that, Sony tells you right off the bat you are not going to make games that will likely be sold to companies. (Most if not all thierd-party developers only deveop in-house for legal reasons)
It was actully the 3rd party deveopers that demanded this, not the public at large. You see, that was happening was the new guys out of college were just having a bear of a time with the PS2. To say it's "difficult to code for" is about as much of an understatement as "outer space is big"
Companies were wasting six months to a year on training on each new deveoper, which was very expensive. They have new emplyees that really coudn't contribute to a project until they were up to speed.
This kit allowed for anyone to tweak under the hood. You gain valube experance so deveopers could hire "right out of the gate" also they didn't have to comb schools. Anyone who consistently produced good code would be considered.
I got mine so I could learn OpenGL and work real close to the metal of a honest to god gaming system legaly. I also wanted to support Sony for making the choice to use linux.
However, I was slammed by the architecture. I knew the PS1 was was very unprepaired for what a PS2 had under the hood. It wasn't a PS1(+1) it was a new Sony system with a ps1 inside it. (Which was locked out, BTW)
That thing has SIX co-prosessers that all had to share a super wide, propritary, 4,096 bit bus in perfect time or the whole graphics subsystem would smash.
What irked me was Sony said it came with OpenGL libaries and it came with MESA that rendered in Software only. Watch gears run in 245 FPS..... ooooh! (It should run 10000+ on accelerated hardware)
It was just too hard. I was plannang on porting epsxe to it (Not as stupid as it sounds) but the way the PS2 was built was so knorked up, I gave up and sold it. I should of at least kept it so I could hack the memory cards, but I had recently quit my programming job, (Yes, I was a paied Linux programmer) and never touched software deveopment again.
