Hi,
First of all, congratulations on such a huge project. It looks great, and it is really really promising.

Now, i have a small question. I am a computer engineer myself, and i was just wondering... how did things start?

I hope i am not wasting your time with this. I just hope the developers will just waste a minute or two to answer this.

As far as i know, there are no documentation available for the different PS2 parts. Correct me if i am wrong. But, i couldn't find any documents explaining how the graphics card works. How to communicate with it? or even the instruction set of the processor. (if there are, where can i find them?)

So, how did you people start? It looks like the very beginning was the hardest thing. Working in a totally obscure environment! How did you mange to get things going great like this? I really admire your efforts...

Thank you very much..
Yours,
someone2

It's all about reverse engineering.. The rest I'll leave to the devS!

You can always take a look at the source code from sourceforge.net

I tried, but there are nearly no comments at all in the code.
Anyway, i am not interested in creating a PS2 emulator. I was really curious to know how did the whole thing start? where did the guys get the info from?

getting the dev's to explain there source code is harder then getting them to do a release. trust me I tried.

To ChaosCode: If you read the source code you understand why they don't want to explain it
also he didn't ask about the soruce code, he jsut asked how thay started to work on the emu.

To someone2: There is a doc on the basic architecture of the cpu. It's not from the ps2 so it doesn't explain all the ps2, just the main core.
It's also known that it's a MIPS 3 cpu with 64 & 128 bit extensions from mips 4 (IIRC), called MIPS r5900.
There are also some docs made by ps2dev scene. And the official (confidential) docs for the licensed developers.
