Announcing SDL PS2 Linux RPMs

Sony has donated a Linux PS2 test box for development, and I have
made available SDL 1.2.2 in RPM format from the SDL download page:
http://www.libsdl.org/download.html

The latest CVS snapshot contains support for PS2 TV output as well:
http://www.libsdl.org/cvs.html

I have also ported Maelstrom to Linux on the PS2. :slight_smile:
It’s kind of fun playing Maelstrom on the PlayStation, on the TV
with a gamepad controller. :slight_smile:
Look for an official announcement later this week.

Feel free to forward this announcement to people in Japan who have
the Linux PS2 beta 1 release.

See ya!

Do you have any advice for people trying to make cross-platform SDL
applications so they will run properly on the PS2?

For example, it seems that one cannot assume the presence of a keyboard.
Are the different buttons on the PS controller sent via the SDL_Joystick*()
functions or as key presses?

Does it have a harddisk or boot over the network? If no harddisk is
present, game state would have to be saved on memory cards. Is this
possible under Linux/PS2?

Yes. Have it use as little memory as possible. Don’t use any resolution
larger than 640x480. If you can design your application so that it can use
640x224, that’s even better. Don’t use floating point for everything.

I’m not sure. The development PS2 has a USB keyboard. The game controller
is a normal Linux joystick device. I presume that the final product will
be the same.

It has a hard drive.

Slight correction, Sony has loaned, not donated the PS2 for development.

See ya!

Hi Sam,

What CPU does the Dev kit run on? Is it a standard i386 CPU or
something more specialised?

Once you have your game ready is it just a simple case of burning a PS2
CD for people with a PS2 to be able to play your game or are there other
steps that must be taken?

Thanks,

Dominique

It is a PS2, a mips processor.

CD for people with a PS2 to be able to play your game or are there other
steps that must be taken?

I have no idea. The kit really is just a beta. :slight_smile:
I am just releasing software as RPM for people who have it to download.
I don’t know when or if Linux on the PS2 will be released as a product.

See ya,

Normal PS2’s are perfectly capable of using USB keyboards and mice, if
you can support them then maybe you should. Of course, you shouldn’t
rely on one being there.On Wed, Aug 01, 2001 at 06:10:38AM -0700, Sam Lantinga wrote:

Bother! said Pooh, as he shot his concealed handgun into a crowd.

I had a question about this (I may have asked before and never gotten an
answer, I don’t know)… but what is supported? I mean, obviously you can do
2D games, but can you also use the PS2 3D hardware accelleration? (Via SDL
Open GL wrappers, native Open GL libs, etc.)?

I guess what I’m asking is, using the PS2 Linux dev kit and SDL, could you
make full-fledged PS2 games using all of the PS2’s features?On Wednesday 01 August 2001 08:53am, Sam Lantinga wrote:

Yes, but you would have to design the game specifically for the PS2
hardware. It would be just as difficult as writing a normal PS2 game.
There isn’t a complete OpenGL implementation for the PS2 at the moment,
that I know of.
