Zaurus - pdaXrom / Zpsx: High Performance Psx Emulator For The Zaurus

« on: July 05, 2007, 02:43:16 am »

Ah ok, can do. I just heard that D+M might not work with R198 for some reason. I must of got it confused with the other key combo.

Zaurus - pdaXrom / Help New Kernel For Pdaxrom

« on: July 05, 2007, 02:33:36 am »

Well Hrw, does your SDL support a framebuffer console mode (fbcon) that rotates the screen from the native portrait mode back to landscape? I noticed that 2.6 kernels don't seem to support SDL as well as the previous 2.4 kernels. pdaXrom's R198 SDL is very slow in X11 mode, but FBCON is very fast, although still suffers from the rotation issues as it's drawing straight to the portait oriented framebuffer. I'm moving back to the 2.4 kernels due to this.

Well I got psx4gp2x up and running on pdaxrom r198.

Something I noticed that will need to change for supporting specifically r198:
- The console (fbcon) SDL is 3 (!) times or more faster than X11's SDL.
- Since the X11 mode of SDL is so slow, console is the preferred choice, issue is the framebuffer for the Zaurus is natively in portrait mode, and needs to be rotated. So I can...
- Rotate the screen in psx4all or wait for a well supported FBCON SDL for R198.

So in the meantime, I think I will make a 2.4 pdaxrom kernel ZPSX. This is only due to it being easier to get things up and running on this kernel and have the support of the "BVDD" SDL. That version of SDL has much better console/fbcon support as it rotates the screen automatically and handles nicer.

The 2.6 pdaxrom kernel supported ZPSX will follow.

Now I have to figure out how to go from R198 to pdaXii. Any tips?

Well I've got the site+hosting covered. The design might take a bit. I will be open sourcing the psx4all project again. Unai is waiting to open source his GPU, until some bugs are fixed. So this may delay things only slightly.

As for the psx4all site. It's down permanently. Just wasn't worth paying for, as there wasn't a webmaster that could design and maintain a site dedicated to psx4all. If someone has the means to register the domain again, and get a site up and running with site design included, feel free to PM me! I'd appreciate it.

koen: One of the members of psx4all does not want to opensource his code at the moment. It will be difficult to go about opensourcing it until he agrees. Unless you're really good at writing a high performance/compatible PS1 GPU? He also has code within the rest of the psx4all. Not to say it won't be opensourced, just not yet. Exophase and I keep throwing around the "start a new PS1 emulator but this time opensource it" often. It just hasn't happened yet and will take time. It really needs to be opensourced though, and I will ask the teammember again to opensource it.

Leads me to a question, would anyone be interested in improving psx4all's code? If it were opensourced? The GTE needs to be replaced, and to be honest I'm close to scrapping a lot of code. It needs serious work to get it running on the low performing GP2X well, which is our goal.

Anyways...
I plan a 2.4 kernel ZPSX release as well.

UPDATE 08/02/07:
New build of psx4zaurus build 080207:
http://zodttd.com

Hi everyone,

Thanks to the kind help of those who donated and supported me for getting a new Zaurus, I have begun work on a new ZPSX. ZPSX is a PSX (PS1) emulator for the Sharp Zaurus. It has the benefit of using my psx4all project and it's MIPS -> ARM dynamic recompiler. Featuring sound, save states, memory card support, and lots of performance, it will be a killer app of the Zaurus once again.

Since my Zaurus came preinstalled with pdaXrom r198, I've installed Meanie's great SP8 fixes. I will be releasing ZPSX for this 2.6 kernel first. I will also try to release a patch for cpuoverclock.py that gives the extra bump in voltage needed to reach 624MHz on the PXA270 (processor in the Z's such as C1000).

For those who, like me, were trying to find the cross compile toolchain for GCC 3.4.x for use with the 2.6 Kernel Zaurus search for this file: cross-sdk-armv5tel-cacko-linux-3.4.6-2.2.5-softfloat.tar.bz2

I'm still adding much more performance to the psx4all's ARM Dynarec so I'm shuffling between ZPSX (psx4zaurus) and psx4gp2x. The GP2X is a Linux gaming handheld that also runs on the ARM arch. It is what I'm basing my new ZPSX version on.

Expect some great things soon from ZPSX.

I have received my Zaurus C1000 from ghost. It is in perfect condition and it works well. It came preinstalled with pdaXrom r1.1.0 r198 by my request. I noticed this distro is actually a bit "off", and the cpuoverclock.py doesn't adjust for voltage increases needed for 624MHz (easy fix though).

Thanks to everyone for their support. The donations helped out so much! I will return the favor with a new and improved ZPSX as promised.

Time for me to get coding!

Up one more donation. I put up some extra money and got the Zaurus from ghost. It will most likely come tommorow (Saturday) or Monday.

Expect great things.

I heard it will be 200 pounds. Which is closer to the $350 range.

New products and alternatives / New Zaurus Successor?

« on: June 29, 2007, 03:35:30 am »

Thanks Snappy! Never knew about umpcportal!
The Kohjinsha sounds cool, but may be considered pricey depending how the Asus Eee does when it arrives.

I liked the looks of the Pepper Pad on there. It looks like a gaming PocketPC.

Just dropped by here to thank Cresho for this.
I too am involved in porting and developing emulators on the Zaurus. It's a great platform for such and I'm glad to see others involved.
Thanks, if you need any help let me know. Looks like you've done a great job so far.

Can someone write up a quick table of these new handhelds emerging including a possible street price? It would be amazingly helpful! Especially with new ones like the Asus Eee, Kohjinsha, Via's UMPC. It get's very confusing also to know what's currently available and release dates. So much info!

Hope that the request isn't an annoying one.

Chero, I had the idea of moving to General Discussions as well. I think a new topic there would be better suited though, as the initial posts on this thread can confuse some.

Merli: Thanks so much! Now we're really close to the goal amount!

Dromede: I'll bring it up with Exophase again and see.
