Home Page Forums MAME Non-Windows MAME Support sdl mame on ps3

Thanks for sdl mame, this stuff is great.

I searched the forums but didn't find anything, so here goes w/ some questions:

With a tiny-little fiddling, I got sdl mame 111u4 to compile & run (albeit with caveats) on a sony ps3 under (yellow dog) linux.

If you don't have a patch already, I can clean it up and hand it over (set PPC = 1 in the makefile, and a handful of #define & #undefs in some source files to make headers happy (maybe better moved to CFLAGS?)).

I had to compile libsdl 1.2.11 from sources (w/ --disable-opengl or so).

I got it to run it w/ command line like this:
./mameppc -switchres -screen_aspect 16:9 -r 1124x644 mspacman

The -r 1124x644 is compatible w/ the ps3's "video mode 3" - the only "mode" through which I was able to get something other than a blank display. I don't think 1124x644 is a 'standard hd resolution', but it worked here.

The image occupies only a fraction of the available screen-space - a 1:1 mapping w/ the original resolution? I tried -prescale (& -maximize) without any difference. I'll keep digging around, but is there something else I should try?

The sound is garbled. Fwiw, I think the SDL test suite playloop sound test has similar issues. I see a reported 96000 hz speed for the sound in mspacman - seems high? - so maybe something there.

Thanks for your time,
Phil

It's stuff like this that makes me a Fedora supremecist On PS3 FC5 SDLMAME compiles and runs literally out of the box with 2 quick makefile edits.

Anyway, the next release will have a CELL target that automates the necessary edits. Post a patch and I'll see what can be integrated without breaking the mainstream distros.

ALSA audio seems to be broken on PS3 Linux - I noticed this in MPlayer and Xine also. You might try setting whatever SDL environment variable to use OSS instead. And finally, running SDLMAME under X will make it much, much happier. You will get (software) stretch when you go full-screen, for instance.

Cool - yeah, the yellow dog was supposed to be sony's favorite pet- but it seems relatively unremarkable? Debian distro was near and dear to me a ways back, good times. Maybe I should get another hard drive and install fedora.

Patch was next-to-nothing in terms of changes, as above, but let me go verify & make it a little more pleasent.

I only got the ps3 a few days ago, so I haven't tried out much in the way of anything yet. Rebuilt the kernel, rebuilt kboot, messed around with advancemame, then found this, ...

Thanks, I'll play w/ the OSS switches & SDL and see if anything gives, try running in X (been running from a virtual console), etc.

The diff is appended - works w/ small additions to the makefile.

I added a couple of comments to clarify use of some of the CFLAGS.

I'm noticing a message now (might've missed a change in my CFLAGS cleanup? Or perhaps stale build file?):
Unexpected boolean option rdtsc queried
... but this doesn't seem to matter, mame continues to execute normally.

mspacman runs @ almost perfect frame rate- though I'm still only able to use the virtual console w/ ps3 video mode 3. Trying under X11, it doesn't pop up a window; I'll poke around more, probably something dumb I did.

The rdtsc message is normal, it'll go away in u5.

Recompiled & reinstalled SDL a few times, tried a bunch of stuff:


SOUND: SDL w/ --disable-alsa does something to the sound- seemingly sounds better than alsa, though not perfect. The SDL loopwave test also still is distorted (in the high-end).


GL: I rebuilt SDL w/ --enable-opengl (found libGL.so in /usr/lib). Yellow dog distro doesn't appear to include <GL/glu.h> (which SDL wanted) - though yd /usr/lib/libGLU.so exists. Commented the #include out and SDL built.

While SDL/test/testgl compiles & links, it fails w/ "Couldn't set GL mode: OpenGL not available".


WINDOW: *none* of the SDL test suite runs in a window -- all video tests go fullscreen, including testwin.c. Even after explicit unset of SDL_FULLSCREEN in video_flags before the call to "screen=SDL_SetVideoMode(h,w,bpp,video_flags)", (screen->flags & SDL_FULLSCREEN) returns set. So no windows - something's fishy.

SDL's testvidinfo reports only a fbcon device with capability of a singular fullscreen resolution of 1280x1024x32.

But if I change to /sbin/ps3videomode -v 2 (or 7) from a console, I can see a testvidinfo "Current resolution" of 576x384 (or 576x460) - even though the log still reports only the capability of a single resolution of 1280x1024x32.

In -v 2 (or -v 7), none of the graphical SDL tests work properly: either presenting a blank screen, or presenting what looks like a "scrambled interlaced" pattern of what the normal image might be.

Seems fbcon driver lacks the knowledge of ps3videomode capabilities, perhaps is the source of the SDL_FULLSCREEN bit always getting set, is the root of all evil?


I'll hack on this a bit longer- but your suggestion of FC5 install seems path of least headache- the yellow dog might do well to get a flea collar.

Got alternate console resolutions to work, finally. Still no SDL window, just fullscreen console. Plays fine, gotta fix sound, figure out how to get joystick & driving wheel working, ...

Made some interesting finds along the way - may be old news, but in case somebody doesn't know:

If you want "true HD 720p" (1280x720 - not have bars on the sides of the screen as per- "margins" as described in linux/drivers/video/ps3fb.c), then use ps3videomode 131 -- NOT 3.

Or, /sbin/ps3videomode -v 3 -f

-f is for "full screen" which I'd've called "no-margin" or "no-border", probably got lost in translation.

If you want a "good mame experience", try ps3videomode 130 (480p) or 135 (576p), if your display device can handle it. After you switch modes (I do it from a virtual console (shift+ctrl+f2), and you have to be su), run mame as per:

./mameppc -switchres -r 720x480 mspacman
./mameppc -switchres -r 720x576 mspacman

You have to match the -r values with the ps3videomode- didn't work for me until I explicitly specified these on command line.

While it doesn't maximally fill the screen, its waaaay better (at least for me w/ a ~200 inch screen via front projector).

Now onto sound...

Ooops, I must be more whacked on yellow-dog scooby-snacks than I realize; fwiw that key sequence for virtual console is ctrl+alt+(f1 or f2 ... f7 brings back x11-rooted console) - not shift+ctrl+f2

whatever, just bang on the keyboard a lot until it gets right.

So trip out - alsa works cleanly for me - its oss (/dev/dsp) that is garbled.

Thanks for the environment variable tip! Maybe that's what you meant to type above, or maybe I'm reading cross-eyed, or whatever. I'm a newbie

I'm using a kernel built from yellow-dog sources.

btw, fc5 is 'not optimized for the [crappy] ram in ps3'. Or at least so says wikipedia: http://en.wikipedia.org/wiki/PS3 Guess the old yellow dog might still have a few tricks up its sleeve. Whatever. Once again, maybe old news, but my reaction is no shit- where's that PSGL???

So, before launching mame, typing this:

export SDL_AUDIODRIVER=alsa

gets nice audio. It works for the SDL loopwave test too, just in case you like hearing the same "I met a woman one night, crying black & blue tears & [something or other]". Where's that from?

I'd like to get the controllers working, throw a stupid front(al lobe)-end in kernel arg init= via an iso9660 image's etc/kboot.conf; I could make a disc even my girlfriend could use. That'd be nice, she likes ms. pac man. Its crazy how anorexic chicks dig games where you eat stuff.

I know it's asking a lot, but could you post a step-by-step guide on how you got this working, like what to what and where to download, how to compile , what options to use, etc...?

Thanks,
Zep--
