(zpsx) Psx4zaurus Public Beta 4 Released

[zi99y]

zottd: are you planning on putting in any frameskipping options? if we can at least have a couple of games running at full speed with gameskip then this emu will be a lot more use

[Capn_Fish]

After bugging people for a whille, I finally got a game working. The other two I tried froze at the black screen after the first block of text that appeared (Square Electronics, Sony, etc.). Is this related to the game, my image, or is it caused by my CPU running at stock speed (I have no clue if this could cause it to hang, but I thought I would mention it)? The emulator said that the game loaded successfully.

Thanks.

It's possible that the first release of zpsx is more fast that the last?
And the speed change between a compressed rom or no?

I'm only able to test with my C1000, as thats all I have as far as Zaurus go. But I am able to overclock it to 620MHz. Just about every game I throw at it at this overclock is fullspeed. A big help would be a page or post listing the various Zaurus' out there and their CPU specs.

The "Load Success" only means that the BIOS was loaded successfully, currently. To test if your ISO is valid, try testing it on a desktop...Windows psx emu such as PSXeven, PCSX, ePSXe, etc. Or on a Linux desktop there's PCSX I suppose. Knowing the BIN file or .Z/.table you have works on another emu pretty much lets me know it's an issue with psx4zaurus.

The CPU running at stock speed is usually a good way to test stability of a game, so that shouldn't be an issue. Overclocking the CPU will give A LOT more performance though. Games on my C1000 at stock 416MHz are slow, but fullspeed at 620MHz.

FF7 on my c1000 is slow in full montion video and in battle.
I run at 624mhz, no sound and without X...
However when I load a saved game, and I want turn on sound, I can hear nothing...

Full motion video (MDEC) is slow/jerky in most games right now. I can get that fixed soon.

Performance tip:
There's a small "trick" I have built-in to psx4zaurus. To change the playstation vsync timing use the following key combinations:

Lower VSync (more performance, possibly less stability, best at around 5000):
TAB + E

Raise VSync (less performance, possibly more stability, sometimes will get you out of instability from lowering the vsync as well):
TAB + R

Can you let me know if setting the VSync to that 5000 mark helps you with FF7 performance? Thanks!

Ok, one more request.

Are there any free/shareware/demo images available in any public place, that we can download and use to test psx4zaurus- as a reference platform?

I've had so far no luck with any of the images I've tried, and can't really tell
if its a configuration problem on my end, or if the images themselves are bad.
A reference file to test, that's *known* to work, would be really wonderful,
if any such thing may exist.

Not all of us have PlayStations at home, and not all of us have known working images, or access to them.

thanks :/

About Vsync: I use it.
I set always at 5000 (500 freeze the game) becouse seems that the performances are improved.
It's true, but (for example) during the battle in FF7 it's too slow.
Now I set 10000-15000, and the battle is very near to fullspeed and the game is very playable (without sound).
Problem that I can found: if I load a savedgame, and then I turn on audio, audio doesn't work;
in some game (like ff7) is better your previous version of psx4all (in ff7 the menu game and the char are displayed wrong).

[Antikx]

sorry for the cross post, but...
I setup a wiki for psx4all on my site, go to:
wiki DOT tyrannozaurus DOT com
I know that there all ready is some info in the OESF wiki and I hope I'm not stepping on toes. I set it up before I remembered (was reminded of) the OESF wiki. If you guys would rather use the OESF, that fine with me.

I've been trying to update the compat list, and info page as I read your posts and try games of my own. Take a look, there's lots of data in it all ready.

PM me here or email me @ montanaq AT gmail DOT com if you have problems using the Wik

[zodttd]

Darth_Sith: Are you using a PAL (UK) or NTSC (Japanese / US) version of FF7? I didn't notice the text bug in the NTSC version.
The issue with sound and save states is a known bug. It's on my "things-to-do" list for psx4all.

Antikx: Is it ok if I sig " wiki DOT tyrannozaurus DOT com " on OESF and the psx4all forum? Sorry about the lack of response lately, been very busy.

Giver' (go for it).
...and no worries, we all have live's outside our hobbies.

Zod I use original CD from PAL version.
With your first release of psx4all (412kb) run fine. With the last the window dialog and the menu in ff7 is broken on bottom, and the text is displayed worse.
About performance I seem that is good the version of 412kb, but I can wrong this...

[stuffman]

The battle menus in FF8 don't display in the newest release.

[Capn_Fish]

Could somebody post the most recent version/whatever works with FF9 (assuming that's OK with everybody)? I don't like registering.

Thanks!

[Capn_Fish]

It says here that FF9 works with Beta 4.3. I have 4.3, but it freezes up at the black screen right after the Square whatever it is logo. Can anybody confirm that it works with Beta 4.3, or recommend/post a beta that does work with it?

Thanks!
