I found a great tool for PS3 Linux that uses a single SPE to zoom in on the center of the screen by a factor of 2X, 3X, or 4X. This helps when running many different games or emulators since you can run at the original resolution (much faster than scaling done by the application) and the scaler tool, using one of the SPEs, takes care of enlarging it.
Here’s where you can get the source (translated page): link to “miya’s Diary” post
Applications I have used it with so far are Quake 2, QEMU running Windows 95 / Diablo-Hellfire, VICE (C64), snes9x-gtk, and sdlmame. Screenshots can probably explain this better than I can, so …
snes9x-gtk running a game at the original resolution:
about to start scaler:
photo of scaler running — snes9x-gtk is still running the game at the original resolution, but scaler has zoomed in on the center of the screen (3X):
Here’s one way to set it up … download the scaler.tar.gz file (which includes source & a binary), save to your desktop and extract it, then copy the included scaler binary to your /usr/local/bin folder:
cd ~/Desktop
tar -xvf scaler.tar.gz
cd scaler
sudo cp scaler /usr/local/bin
Or to compile it on YDL 6, just enter make from the scaler folder. I had to install some additional development libraries on my system — this might take care of getting them all: yum install *spu* *ppu*
There are many different ways this tool can be used … for example, you can include it in a script to start Quake 2 like this:
#!/bin/sh
scaler -s 3 -t 3000 & quake2.sh
killall scaler
The -s switch tells it how much to scale, and the -t switch tells it how long to run. Running Quake 2 at 320×240 on a 1280×720 screen would normally result in the game screen being very small, but fast (about 150 FPS 94 FPS timedemo) on the PS3. Using scaler you can run it at 320×240 with 3X scaling so it displays at 960×720 and still runs at 150 FPS around 90 FPS (timedemo test), whereas if you run Quake 2 normally at 960×720 you get around 25-30 FPS. Or course it looks better when Quake is actually running at 960×720, but the additional speed you get from running it at 320×240 and using scaler is great!
Or you can set it up so you can zoom in on the screen at the press of a key using custom keyboard shortcut commands in GNOME. See here for info on setting up custom commands:
Create custom keyboard shortcuts in Linux
EDIT: You’ll need to install gconf-editor for this — yum install gconf-editor
I set mine up so I can use F9, F10, F11, and F12 to scale 2x, 3x, 4x, or turn scaling off.
EDIT: Hmm… it seems that was a poor choice of keys, though… 
EDIT: Here’s a post that describes how you can set up the keyboard shortcuts for the scaler tool in more detail:

Do you think XP would run smooth on the PS3?
Have you had ANY luck at all with diablo2 running on the PS3? - Could it be the OS you used?
March 24, 2009 at 7:36 am
billb
XP will definitely run slower than previous versions of Windows on the PS3 (via QEMU).
Due to the higher memory requirements of XP, I don’t think it would help for Diablo 2. With the PS3’s PPE core having to emulate a full x86 machine I think it’s just not going to be fast enough no matter how you do it.

I got the Java plugin working for firefox but what I want to do is to be able to run Java apps from the YDL 6.1 desktop.

Hello billb:
Sorry for my poor english, but i don’t control your Lenguage.
My Nickname is Piollotorm and I’ve use your install guide to compile SDLMame that you posted in http://pleasantfiction.ipower.com/bodega/viewtopic.php?f=6&t=18&st=0&sk=t&sd=a&hilit=sdl+mame#p28. It’s very good.
I’ve translate (freely) to spanish by petition of one user forum (www.elotrolado.net). I´m a simply user.
I tell you if you don’t want to make it public and you want i erase it.
A lot of thanks.

Hey bill, I am having some issues. Now I am pretty much a noob to YDL in general, but here is the issue I am having. I went to do this sudo revisited stuff, and it kept saying sudoers was a read only file and wouldn’t let me change it or anything, even in root. So I made a new file, copying all the content of the original, then named it sudoers, and erased the old one (probably a stupid move lol) but now I get this error when I try to enter sudo, it says “sudo: /etc/sudoers is mode 0644, should be 0440″ and it doesn’t allow me to enter sudo. Is there a way to fix this? or am I screwed? Again, I’m new to this stuff so all help you can afford would be appreciated! Thanks!

I need to update that guide including the step to make the sudoers file writable. You can fix the issue you’re having with (I’m assuming you’ve already edited the file and made the change):
su -
chmod 0440 /etc/sudoers
exit

Any chance you could attempt to run Grim Fandango using this method? Running that would be my only real reason for going through this process and I don’t want to bother if it won’t work. Thanks.

@morgan — I’ll give that a try. Also it appears there’s a sub-project of scummvm that is in the works (http://apps.sourceforge.net/mediawiki/residual/index.php?title=Main_Page) but I haven’t tried it.

Hey Billb , I’ve been using ydl for about a year. Still no good at running outside gui. Since 6.1 I can’t find any p2p programs that work. Will never get Usenext on this thing due to the mono issue., but do you know of anything?

I use deluge:

After setting up repo:
http://pleasantfiction.ipower.com/bodega/viewtopic.php?f=11&t=21
Then just:
yum install deluge
The version I have in the repo is a bit old, but it works for me.

billb, do you know if anyone tried compiling snes9x with IBM’s Cell xlc compiler (aka Octopiler)? I am curious to see if the emulator can be enhanced with xlc’s automated SPE offloading.
I was thinking of taking a shot at this myself, but I wanted to check here first.

Sorry, I don’t know of anyone who has attempted that.

Hey billb. I’ve installed YDL 6.1 on my PS3 and then updated it with as much stuff as I can get my hands on (via yum). I’ve also installed the port of VLC and I’m able to play movies and mp3 fils quite sucessfully. What I am having a problem with is sound (and video) in Firefox. At this point I’m unsure what to do–I’ve had a look at the the available plug-ins, but none of them, seems to have anything to do with sound. Any ideas what I can do to get this part working?

You know what that means - pumpkin guts. They’re gooey, they smell a bit funny, and they’re an easy way to quadruple the weight of your garbage can.
Stickiness aside, what CAN you do with pumpkin guts?

I’m due to inherit shortly a PowerPC based Mac (well at least I think it is as I’m sure it’s over a year old) and I was wondering what my hope of running games on it might be.
I would idealy like to run Ubuntu on it as I like it as an OS. It looks like I wont be able to run games using Wine, are there any other options?
July 18, 2009 at 11:17 pm
ynah2q3
Yes that’s exactly how you would do it. However most software has been written to make use of the environment variables so that files can be stored in the users home folder such as save games etc. If you go to the terminal and type set you can see the entire list of environment variables for the current user.

Have you got the fluendo mp3 codec installed? that should get sound working in firefox but videos (youtube etc im guessing follow the sfwdec tut on http://www.yellowdog-board.com/viewtopic.php?f=19&t=3712&start=120&st=0&sk=t&sd=a, sorry if this isnt allowed on forum rules but im new to ydl net :-/

Do certain emulators work better than others for various systems?
i.e. For Genesis, does XE work better than sdlmess? For 2600 does stella work better than sdlmess (not listed but I saw in a post that it does work)? Does the order the emulator is listed (when multiple emulators are listed) indicate a preference?
Basically is there a way to tell which emulator is the best to use for each system on the PS3?
PS: I couldn’t type in the anti-spam word on Chrome, it wont let me type in that box (it goes back to the website box).

@knicknak
Yes, XE works better for Genesis, and I’d prefer stella for Atari 2600 over sdlmess as well. Here’s a short list of what I’d use:
Amiga — e-uae
Apple II series — sdlmess
Atari 2600 — stella
C64 — vice
Coleco — sdlmess
Genesis — xe
NES, GB, GBC, GBA — mednafen
SNES — snes9x-gtk

does anyone know where the config file .uaerc is saved when you install euae from the dribble repository ?
No matter what changes I make to the one .uaerc file in my home directory, it does not seem to have an effect, cant even change the resolution. Anyone knows if you can use hardfiles with euae as well ?
thanks for your help !
