Demo for Playstation 2

group org: malfunction
Tech info:
----------
All code was implemented by me (mi-ku/Altair) except sound (I have used
ps2snd lib from homebrew PS2SDK) and jpeg decompressor.
Our demo framework utilizes PS2 specific features like Vector Unit 1 custom
transform and lighting with clipping and backface culling manually
implemented in Vector Unit assembly.
Framework is writing to and reading from hardware memory and registers
directly without use of any foreign code except JPEG decompressor and
libraries except ps2snd.
During implementation of this demo I didn't have any working debugger. I've
been using printf and memory dumps to analyze bugs. At the beginning it was
really hard to find out why things weren't working as they should (or I
expected). So... yeah, implementing all of this was really "interesting"
experience.
How to run:
-----------
Real hardware required. You'll need real console to run this demo properly,
modded or with FreeMCBoot. This build works with ps2link and PCSX2 emulator
However on emulator demo will run without sound. To run it with ps2link you
should have ps2link running on console with proper network configuration,
then on PC use ps2client with following command:
ps2client -h CONSOLEIP execee host:altair.elf
where CONSOLEIP is IP address of your PS2.
To run it on PCSX2 "Enable host file system" option should be enabled.
