Psx Running On The Zaurus

[danboid]

Oh dear!

I never meant to start an argument- I was only asking about the state of 2.6 on cxx00- sorry for trashing your thread zodttd  

zodttd- don't bash hrw. Hrw puts a hell of a lot of time into OZ as you know and so you can't expect him to be able to help you with the complex task of kernel hacking and he always answers my questions promptly. Have you tried asking koen or any of the others on #oe for help? Of course there is always the OE wiki:

http://oe.handhelds.org/cgi-bin/moin.cgi

but I suppose you've read that already?

RP- from what I've read it sounds like you know what needs to be done and how but you don't have the time. Could you not outline the process for zodttd, sashz or whoever so they  could fill in the gaps and provide this ideal solution you envisage? They're obviously very keen, it would shut me up and we'd have lots of happy Z users!

Don't slate, collaborate!  

[zodttd]

Heh. Sorry about my nasty post. I'm venting.
I got most of what was needed finally to develop for OZ, it took awhile digging through old posts, wiki's, and sometimes outdated instructions on OE. I've read that there's been a problem with getting stuff documented for them.

Anyways, back to ZPSX. I got the latest codebase from Unai and Chui and it has been cleaned up. Once I get it integrated with the GP2X, I will get it working on the Zaurus as it's a quick edit from that point.

I'm speaking to Tinnus on how to get a "C" Dynarec implemented real fast to get everyone a release with a performance boost and more functionality. It would be a stepping stone release.

Unai has found out the cause of what was stopping us from getting a decent frameskipping routine going, without the "timewarp" effect. So with a basic dynarec, frameskipping, and interlacing, things will perform much better. Compatibility should be increased as well, as less "tricks" will be needed to get performance, that cut down on compatibility.

If the pdaXrom 2.6 kernel release isn't ready this week, I'll release it for the current pdaXrom. So expect a new release soon.

[danboid]

All sounds good now

Seems you know more about this new pdaxrom than most- we might be able to expect a 2.6 based pdax in the next week or so or is sashz just releasing his patched kernel? I hope sashz doesn't mind you leaking his secrets

Personally, I'll be totally stunned if you ever manage to get (almost) full speed psx emu with sound out of a gp2x. I think there is a much better chance on the clamshell Z.

zodttd: sorry but during last months I concentrated rather on making OZ releases then on helping users with complex tasks (like using OE, getting stuff from OE to use it with any other enviroment etc).

Currently my main problem is lack of time for myself - spending >50% of time with computer is something which I want to avoid.

BTW openttd - last version which I build was 0.4.0 which (thx to YoG) now works (files was missing in package). It have some build errors when 0.4.7 tried..

what? only 50%   I've been doing 12-18 hrs a day... for the past 6 months. :-/

I need a vacation.

recompilation time now. Tomorrow will try upload new bootloader and system for Cxx00 at first.

Is there any way to get this running on an SL-5500 with the Sharp Rom v3.13? I would really like to be able to play playstation games on my zaurus. If there is a way will someone please post how?

[zodttd]

I'm pretty set at releasing ZPSX for pdaXrom only.
I could try a Sharp ROM version eventually, but since I don't normally use it, it might be awhile.

Sashz: Sounds good. Hopefully things are going smoothly merging to kernel 2.6. Keep me updated when you get a chance. Thanks.

I made a compile of ZPSX based on the latest codebase by Unai, Chui, Tinnus, and I. It's running REALLY well on pdaXrom Beta 3. With the improvements of Kernel 2.6, it should be a great release.

So many improvements have been made to ZPSX, it's hard to list. Compatibility is way up, as is performance. I just need to get some of the "fluff" such as save states tested.

Great! I can't wait to try it out. I am actually without a Zaurus right now - I just sold my old C3000 and got a new C3200. Hopefully by the time it arrives beta 4 will be done and zpsx will be working nicely on it .

Do you  have any ideas if titles such as final fantasy 7, 8 and 9 will be playable with the new release? I've been waiting for an excuse to play those games again, and I think this could be it .

Also, did you get my PM zodttd?

Hey Zodttd

How does this version compare to the one you are working on for the GP2X.
I am curious how they compare. I don't own a Zaraus but I am thinking of getting one.

[zodttd]

Phill: Sorry for not replying to the PM. I was flooded with response to the upcoming GP2X release of GP2PSX. Glad to see a new UK seller of the Zaurus.

ZPSX can run Wipeout 1 fairly smoothly. Einhander runs well. And I'm betting FF7 is playable now. I'll test it in a second. Remember, this is all without the dynamic recompiler. Expect twice the speed, and possibly more, of this upcoming release, in the next release which will have Unai's new GPU as well as a recompiler.

FF7 uses an odd size resolution for it's menu system (the PSX has a assortment of supported resolutions that it can switch mid-game). Right now I have it clipping off the edges, so the menu is crisp and clear instead of scaled. But some information is being cut, so I'll probably use a scaler instead of that clipping routine. It might slow things down a bit, not sure how much yet.

Unai, Chui, Tinnus, and I came up with the name PSX4ALL for the codebase our PSX ports work off of. It's site will be up and running shortly.

Oh, an ingame menu system is in the works now. It's fluff, and is mostly helpful for the other ports that dont have a keyboard. But it will be cool regardless.

I'm testing the latest codebase on the ZPSX on a C1000 overclocked to 624MHz, using pdaXrom Beta 3. Will give results in a second...

[flexibyte]

Sounds good. I would like to help with testing as much as I can. I have LOADS of original PSX games, because I never sold any, so I should be able to double your list of compatible/not compatible games

Would it run on the SL-5500 with pdaxrom?

[Dima202]

Is this a joke?
There is not way Zaurus can handle psx. lol
This has got to be a joke!
It's impossible!
It bearly runs FireFox!
Tell me this is a joke!

Update- Heck, Visual Boy Advance is bearly playable! ---Gameboy emulator!

I agree it sounds too good to be true, but from what I have read the PSX cpu is very easy to emulate in comparison to other cpus, so I presume this gives it a boost over harder systems to emulate. Firefox runs slowly because it has not been designed for portable devices, and firefox is a whole different kind of app.
