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). smile.gif

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. smile.gif

A new build of psx4zaurus has been made:

For downloads and discussion, please use:
http://www.psx4all.net/

New in build 4:
- Improved performance for games such as Tekken.
- Now includes both a CACKO build and a PDAXROM build.

pdaXrom blits to the screen much faster than Cacko 1.23 with BVDD SDL. And with pdaXrom's overclocking ability it outpaces Cacko. But Cacko is faster clock-for-clock.

Cacko users now have psx4zaurus though! Try it out and let me know how it goes. smile.gif

I'd really appreciate at least a "hello" in the psx4all Zaurus forums. It will give me a feel for whether Cacko users really want this project.

Thanks!

Hi everyone,

psx4zaurus, also known as ZPSX, has a new version out for pdaXrom users.
For more information, head to:
http://www.psx4all.net

Be sure to post a comment in the news thread after downloading.

If you need assistance with psx4zaurus, let me know in the PSX4ALL Zaurus topic.

Thanks! smile.gif

I heard that the following loads the video acceleration for my C1000 in Beta 4:
modprobe pxafb_overlay

After using modprobe to load the module, you can use /dev/fb1 to access the video accelerated RGB framebuffer overlay. It's like BVDD but without the hassle.

Some issues I'm having with pxafb_overlay in my PSX emu:
- Is it possible to change pdaXrom's /dev/fb0 to 320x240, so the overlay isn't a small part of the screen. I prefer to keep 320x240 then scale up to 640x480, for performance reasons.
- Since this is an overlay, colors seem to "bleed" through each other depending on it's hue. Is there a way to prevent this from occuring with performance kept in mind?

ZPSX is coming along well. Now we have CPU Overclocking, and video acceleration. Once I get video acceleration working a release will be made.

Thanks,
ZodTTD

Well I had started a thread about my PSX emu on pdaXrom, but the topic of the 2.6 kernel on the pdaXrom came up. To keep the threads seperate, if possible, post about the 2.6 kernel here.

[removed my flame/rant at Laze's request] smile.gif

Thanks for working so hard on pdaXrom guys and the help you've given me sashz. Can't wait for 2.6 kernel to come out. If you need any assistance let me know. smile.gif
