you can write your own software mixer that can decode MP3 on the PS2 so I
can't see why you can't do that with ogg, however, even mp3 is processor
intensive and programers are not going to give up that much processor power
which will decrease or detract from the rest of the game. However, I'm sure
there are some people out there that have been able to work around this.
Regardless, ps1 and ps2 are a pain in the ass to get soudning good, but
definetly possible.
Anyone on this list programming sound on the PS2, or any other game console
for that matter?

Subject: [vorbis] Vorbis for PlayStation
Hello.
Some friends of mine were playing with a PlayStation one day.
And after playing some Games they pushed a normal Audio CD into that
thing - and the music began to play. A crazy idea came into
my mind.
Just imagine: There are millions of PlayStations spread worldwide.
If it was possible to port Ogg to PS this could help to bring
Vorbis where we want it to be: Millions of families were
able to play Ogg-CDs in their living-rooms.
Does a PlayStation have enough computing power to decode Ogg Vorbis?
Is it possible to port a decoder to that platform? What
about license fees?
I know that porting the codec to PlayStation is not sufficient.
We also need a Player-Application that has to be on every
CD as we can´t upgrade the PS-firmware. So it is necessary
to write a tool that creates Ogg-PS-CDs, too.
Ideas?
bye,
Maik Merten

actually, I see your question deals with just being able to "play" a
CD with
ogg encoded files. I don't know for sure but I would geuss that the ps1 is
to weak for this, but you probably can do this on the ps2.

Vorbis is being used by some manufacturers for playstation games. I cant
remember when I read about this, but it has been discussed on this board in
the past. Try checking some of the older posts if they haven't been deleted
yet.

I'm not so sure the PlayStation 1 would have the power to handle Ogg.
It's a
33 MHz MIPS 3000 in there. There is no floating point support. Integer math
isn't entirely speedy. It's basically about 100 times slower than a
contemporary CPU. There is a GTE coprocessor chip that can do faster math
stuff, but it's designed for geometry, and I'm not sure you could make
Ogg
math work on it.
The PlayStation2 on the other hand would have plenty of power to handle Ogg.
Aside from the CPU, I think the bigger issue is how to deal with Ogg's on
CD's. First off, the CD with the player on it must be a licensed PS2
product, and the media has to be pressed and encrypted by Sony I believe
(unless your PlayStation is chipped). Then you have to switch in a regular
non encrypted CD - I'm not 100% sure this is possible unless it's been
chipped - although my gut feeling is maybe it is. As well, even if there was
a player, it's going to be a commercial product, and you will have to pay
$$$ for it.
Really if this was something desirable and didn't involve much hassle, I
think you at least would have seen some MP3 players for PS1/2 quite some
time ago. I certainly would appreciate my PS2 being able to handle MP3's and
Ogg's but I'm not sure it's going to happen any time soon because of
all the
roadblocks. Anyway, I'm not 100% sure about some of this stuff so don't
let
me stand in your way from writing one.
Thanks,
Dave.

And it will be faster, soon. Working on it... (datapoint: mpg123: 38x realtime. vorbis: 30x realtime).> which will decrease or detract from the rest of the game. However, I'm sureHis idea was not playing Vorbis in a game; rather, he wants to use his PSX as a kind of mp3man. Should be very easy to program, if you know how to program a playstation, that is.

On reading this thread with interest, I couldn't help but wander why no one has mentioned the old Net Yaroze for the Playstation. This consisted of a Sony Playstation in Black, that had a serial port on the back, that allowed programs to be sent from the PC to be executed on the Playstation. This came with a PC based C compiler with libraries for the Playstation hardware, and was designed for hobbyest use. I think that this has now been dropped, but whilst web searching, I came across an interesting site: http://www.geocities.co.jp/Playtown/2004/psx/ny_e.htm An independent software developent tools (based on GNU C/C++) site. The english does look as though its been translated from Japanise mechanically though. Anyways, I thought this might be of interest regarding the original posters idea.
