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

Sure, I'll rewrite once I get to a good point.

R. Belmont endorses fedora core 5 (6?) linux distribution & runs in X. He reports it builds nearly out of the box (true for yellow-dog linux too- see above makefile changes, probably rather similar). You might prefer to go his route- he's way more clued in to current events than me; I'm just getting underway.

I used yellow dog 5 linux distribution & the "frame buffer console" driver. Not running X should give a little better memory utilization, but has downsides like using a fix-sized screen.

I've got a lot of shit dropped on my plate just today, but I'll post binaries @ my site (rosemary.dyndns.org) if there are no objections. Hope to get sixaxis online 1st (might just work w/ ps2-style controller configuration?), & I've got a ps3-bootable linux .iso (just a 'rescue-disk'-type filesystem) now, but need a front-end.


As for what to d/l, I got yellow dog linux 5 over here:
http://www.terrasoftsolutions.com/resources/ftp_mirrors.shtml

I got sdl mame 111u4 source from a thread on this fine site (I bet u5 works fine too though I've not tried yet)?

d/l-ed libsdl 1.2.11 sources from http://libsdl.org/

That's it! All the tricky parts should be documented above, albeit longwindedly.

BTW, upgrade your hard drive if you want to do 'serious development'. Finding a "sata extender" cable was not possible here in the CA bay-area. I got mine from cpustuff.com, but there's probably other good places too? I use a 22 pin extender & a 7 pin extender. 22 pin fits securely in the ps3 backplane (7 pin doesn't lock securely- you want a secure fit). Then hook the 7-pin off the other end of the 22 pin to the drive. And I hooked up a separate power supply up directly to that drive (I used a sata 3.5 inch 750 gig seagate). Its fragile, but it works fine.

22 pin extender: CUS22MF12
7 pin extender: SATAMF12I
power supply: (the one from this should do fine) SATA-2352

Thanks,

I already have YDL 5 installed (the december version)

Sounds like a project for this weekend

one question, how do I stop X from booting up at the kboot prompt so I stay at the command line? I guess thats what you mean in the post above where you say "Not running X should give a little better memory utilization"

Zep--

FWIW, there are *very* few games in MAME for which memory past 128 MB or so matters a bit. People happily run it on the Xbox with 64 megs all the time, for instance.

I'm a clueless newbie about memory constraints for instance- that is useful, thanks.

So text-mode yd boot? try "ydltext" at kboot prompt?..

Moreover, I believe that the otheros.bld (aka kboot, which we all installed on flash) checks if there is media in the drive. And if that media has an /etc/kboot.conf (use an iso9660 w/ rock-ridge extensions, such as "mkisofs -R -o ../foo.iso ."), it uses that media's kboot.conf OVER its own flashed version.

If my memory serves me well, that kboot is just a gzipped vmlinux w/ an embedded ramdisk, fwiw.

So you can make a bootable disk by specifying appropriate kernel argumentation in your own /etc/kboot.conf (on the cd/dvd/bd).

Ps3 reads cdrw (& bd-re > v 1.0!), btw, so you can avoid coasters.

I need to get chroot/switch_root working, will decrease iteration time...

I've got a ~50 meg uncompressed .iso that boots straight to mspacman -- but alsa is failing to start properly, fails to 'find card 0' (not literal quote, but thereabouts).

I've got every file mentioned in a (good) "strace ./loopwave" (SDL sound test) on that .iso.

I'm uncertain what the issue is, maybe my eyes are blurring out 8) , may be due to the read-only nature of the cd-rw with which I'm experimenting, maybe I should use a ramdisk, maybe lack of devfsd (I effectively mknod-ed all the entries in the cd's /dev directory). Well, a few avenues to explore.

I posted a ps3-bootable linux .iso (~17meg, w/ only "robby roto" - thank you jamie!) - alsa is still failing, but just so you have some pieces against which to regress. I'll look more tomorrow, but fwiw now:
http://rosemary.dyndns.org/software/ps3-mame-cdr-test.iso.gz

I think you'll be a happy camper if you add the -nokeepaspect parameter..

For those in the know: with this, where does the actual scaling take place: mame core, SDL-mame or the SDL layer?

The scaling in this case is done in the MAME core. (Which is why hardware OpenGL is really the preferred scenario - unfortunately that's up to Sony and NVidia).

Thanks for the tip- I'll give -nokeepaspect a whirl.

Sound was a matter of loading a few kernel modules, as per:
/sbin/modprobe snd_ps3pf
/sbin/modprobe snd-mixer-oss
/sbin/modprobe snd-pcm-oss

The latest bootable iso is 52 meg uncompressed (not optimized yet), about 18 meg .gz

I believe this iso will boot (straight into mameppc robby- see "/mame/runscript" in the iso for details) as long as your distribution uses a kboot loader.

Do other distributions (besides yellow dog) use kboot on ps3?

Old version is replaced by new "w/ sound" version here:
http://rosemary.dyndns.org/software/ps3-mame-cdr-test.iso.gz

Hope to flush out the sixaxis & front-end; more soon.

Got the sixaxis controller working, to a degree. Replaced downloadable .iso.gz with the latest sixaxis version:
http://rosemary.dyndns.org/software/ps3-mame-cdr-test.iso.gz

Was necessary to load a few kernel modules (see the .iso '/mame/runscript' -- total image could be much optimized), but seems to be workable:

There may be better configurations - stuff in /mame/cfg/default.cfg should generally work, though only for a single controller, etc. I hope to make this more elaborate in days to come (more controllers, etc.). Not perfect, but closer.

Best I have figured for now:

Wait a while, while things load. It takes a bit, have patience. At the copyright 'ok' screen, press (& hold a few secs) the ps3 sixaxis 'ps' button. Then, twiggle the left analog control left & right. The left-hand digi controllers should work from that point on?..

On the 6axis, R1 == insert coin, L1 == P1 start.

Works for robby the roto & ms pac man, far as I've tried.

Front end hopefully soon - more, as its ready.

Nice! Does YDL come with the sixaxis driver or did you have to add that?

Do I have to wipe my current YDL install to use your ISO, or can I make it boot from my current kboot: prompt? If i can boot it from my current install, what do I type at the kboot prompt once I have your image burned to CD?

Thanks,
