Unless he used a cheating device, as Sephiroth is a character avalible in the Nibelheim flashback. Although he is AI controlled, but that could probably be fixed in a similar manner.
Yep, I did this with a cheat cartridge years ago. Good old action replay.

- Crash Bandicoot 2 - The Wrath of Cortex- Works very well, I think it would be playable once the FF7 is fixed. Because I actually almost finished a stage hehe

A misunderstanding of what I said I think. FF7 = Final fantasy 7.. a game , from you use of the word FF7 you seem to think its some sort of part of the PSX or emulator?

Also, crash bandicoot 2 works? I couldn't get it to load, it just froze my Zaurus. Did you do anything special to run it?

You quit by pushing backspace if you're wondering (put it in docs please ZodTTD)

lol... Thanks for that, I was resorting to randomly mashing the keyboard to quit.

Final fantasy 7 runs faster now, but its now full of glitches. In the old version it was perfect - just very slow. Now its almost fast enough to play (without overclocking - as I couldnt seem to get overclocking working on 1.1.0beta3), but the glitches make it unplayable. Some of the sprites in game are not transparent like they should be. Also its reading some textures from the wrong area of memory it seems, since I am seeing part of the font textures in some unusual places (like the boarder of the dialogues). When I got to the first save point and pressed triangle, it immediately did a segmentation fault.

Tony hawks didnt load, crash bandicoot 2 didnt load, raiden was too slow. Thats all I've tried so far, because when a game doesnt load I have to reboot to try another.

It's a step back in some areas, but It's definitely faster in FF7. Keep up the good work, and I'll keep my dream of some day playing final fantasy 7 wherever I go .

Hi everyone,

Sorry for the lack of a release. There's been a lot more additions to our psx4all codebase that ZPSX is based on.

I wrote a threaded interpreter, which is a slightly faster version of the old CPU interpreter. Lot's of large speedups in the GPU have been made. But the biggest addition of all is the option for underclocking the PSX. By underclocking, the GP2X handheld (at 266MHz) reaches speeds of over 30+ FPS in-game on titles support this method. I'll get it ported to the Z asap.

Once again, sorry for the delay. The GPU was holding the release back, then I waited for Beta 4, and now the GPU needs a slight update again.

By underclocking the PSX? I can't picture how that would help, but at least it makes a difference . Is the dynamic recompiler still being worked on? Also - from your experience so far, will the emulator run games faster/better on the Zaurus than the GP2X?

Nice work. There's a lot of stuff there that I was planning on compiling myself, so this will save me lots of time.

Zaurus - pdaXrom / I Got Pxafb_overlay Working With Zpsx...

I did a test with pxafb_overlay using my current build of ZPSX. Using fb1, it performed *at most* 1 or 2 FPS faster than fb0. It's so close to fb0, that I'm wondering what is needed to get the "acceleration".

How did you go about getting /dev/fb1 working?

try doing:
modprobe pxafb_overlay
and then /dev/fb1 should work

Yes, I tried this but it doesnt seem to be working. :/

In C860: "modprobe: Can't located module pxafb_overlay"
This is supposed to work in beta 1 or is this only beta 4 thing?
[div align=\"right\"][a href=\"index.php?act=findpost&pid=128181\"][{POST_SNAPBACK}][/a][/div]

This is only in 1.1.0beta4 (with 2.6 kernel) .... I thought versions before beta4 had bvdd in mplayer which makes it fine for mplayer anyway?

Sorry - just tried with SL-C3200 - So should work with any Cxx00 model. Please try if you have a different model though and let everyone know if it works.

I have managed to get mplayer working with 640x480 videos - smoothly.
You still need to re-encode your old videos though, because they need to be encoded sideways.
Eg.
- Download pocketdivxencoder (free)
- set device type to the 640x480 E800
- in advanced options set orientation so that the pda is rotated to the left on its side (2 clicks)
- Set desired video quality options and encode

Now copy the video to your zaurus and type (works best outside of X11):

# mplayer -vo fbdev -fb /dev/fb0 yourvideofile.avi

and there you have it. It should play roughly full speed. Let me know if this works well with your videos and if you have any more tips.

Also, isnt /dev/fb1 supposed to be even faster? - only I cant get that working with anything, not just mplayer.


Enjoy,
Phill

Ahhh, I know why you didnt notice a difference in SDL...
Set the following to use /dev/fb1 in SDL, if it even will work:
modprobe pxafb_overlay
export SDL_FBDEV=/dev/fb1
export SDL_VIDEODRIVER=fbcon

Problem is, using fb1 isn't working for me. fb0 is. fb0 is faster than whatever the feed in beta 4 is defaulting to though. Only thing is, it's not rotated. The framebuffer needs to be rotated for landscape for Z's. So some SDL work will be needed. I could do a iwmmxt enhanced rotation in SDL and get 1.2.9 working with fb1 if needed.
[div align=\"right\"][{POST_SNAPBACK}][/a][/div]

Go for it
Yeah, the problem was - I didnt know what to set for SDL_VIDEODRIVER - fb0 works now and mplayer seems a little faster. It is rotated, but I could always encode sideways.
However - has anyone tried:

# mplayer -vo fbdev -fb /dev/fb0 myavi.avi

This plays it stretched accross your desktop sideways again but at FULL speed.
Without sdl or fbdev -> roughly 1-2fps
With SDL /dev/fb0 -> roughly 5fps
With -vo fbdev -> full speed (so thats about 25fps)

I am going to try encoding a video in 480x640 sideways and see if it goes full speed with -vo fbdev


EDIT: yep it works - see my new post: [a href=\"https://www.oesf.org/forums/index.php?showtopic=19543]https://www.oesf.org/forums/index.php?showtopic=19543[/url]

Great news!
Could you explain breifly how to actually use the frame buffer?
I read something somewhere about just setting the SDL_FBDEV variable like this:
export SDL_FBDEV=/dev/fb1

Is that it? After that all SDL apps will use the accelerated framebuffer automatically?
I tried this and didnt see any change to my already compiled SDL apps.

Zaurus - pdaXrom / Zaurus Faster In Portrait Mode Than Landscape?

No hardware rotation in PXA27x, only software.
Default LCD orientation 480x640 - portrait. For landscape that uses software rotation, its why landscape mode slower.

For PXA27x acceleration:
modprobe pxafb_overlay

that will create 3 devices:
/dev/fb1 - Overlay1 - RGB modes only
/dev/fb2 - Overlay2 - RGB and YUV modes
/dev/fb3 - Hardware cursor (128x128 max)

for initialize overlay, you need write info about resolution and mode with ioctl FBIOBUT_VSCREENINFO to one of this overlay devices, like as for normal framebuffer. Than get info for device as for normal framebuffer and use it.
I will post sample sources later.

Sounds interesting. I'll be looking forward to the samples.

Thanks for the heads up on the donation link Phill, it's now fixed. I was wondering why I hadn't received a donation from the Zaurus community yet. Time to get working on ZPSX so that link has some more use.
[div align=\"right\"][a href=\"index.php?act=findpost&pid=127909\"][{POST_SNAPBACK}][/a][/div]


Donated! And I encourage others to donate too. This is one of the most interesting projects on the Zaurus!

I was able to get the bvdd driver installed on Beta 4, and it seems to work, though I was testing it with bvdd enhanced SDL, and not mplayer.

I got the bvdd.0.4.0 IPK, and installed it. I'll put up instructions for the latest revision to beta 4 if needed. I think it was bvdd that I needed to unpack the IPK and manually install it due to some folders not existing that it wanted to unpack to.

Either way, I have a /dev/bvdd and a working init script. So I'd imagine it's worth a try installing that IPK and seeing if it works with mplayer. If someone tries it out with mplayer, let me know if it works for you.

Thanks

Awesome news. I am very new to pdaxrom and the zaurus in general (I used to only run OpenBSD and use it mainly as a server), so just the fact that I can get some kind of acceleration for SDL working in beta4 sounds great to me . I've been programming my SDL to be playable for the Zaurus with no acceleration, so this should give me some more leeway.

Can you perhaps point me in the right direction to setting up SDL to use bvdd in my programs?



I've been running beta4 since this release and its been great - I have my XFCE 4.4 beta environment setup nicely but with 1 thing missing -> Is it possible to enable XComposite? I tried looking for an XFree config file but couldnt find anything. Hey, I got it working beautifully on OpenBSD  (in portrait screen mode) - everything ran incredibly smoothly - so you can't say it will be too slow. It may slow something things down, but it would brighten up my desktop when using just text editors, webbrowsers etc.


Thanks,
Phill



EDIT: zodttd! your paypal donation link in your signature doesnt seem to be working. It just takes me to a page that says: "You have entered unsupported characters for this field. Current available language character types are: European, Chinese, Korean, Japanese, and Thai. Please try again."

Also... i cant find this bvdd ipk  where is it?

Zaurus - pdaXrom / Zaurus Faster In Portrait Mode Than Landscape?
« on: May 19, 2006, 06:32:34 am »
Hmmm yeah... great... so the Zaurus is using some of its power just to rotate its screen to its default clamshell orientation.

Whenever I saw iwmmt i always thought that was hardware acceleration for the older devices for some reason. How can I enable iwmmt support in my SDL apps for example?

And would you think it would be wise to go ahead and design my games sideways?
