EDIT1: Fixed download link!
EDIT2: I've set up a psx4gp2x section in my very active forums at www.zodttd.com. Though it seems its pretty empty currently.
POST OF THE LATEST RELEASE: http://www.gp32x.de/board/index.php?s=&am...st&p=575007

Hi everyone!

I said I'd be back with a release of psx4gp2x when I learned more from trying other platforms, and here I am...with a new build of psx4gp2x!

Keep in mind this is a test build. Think of it as a rough beta.
- There's no pretty interface, as it's the standard old psx4gp2x GUI. I will soon move over to allowing it to interface with a menu system.
- There's no support for BIOS emulation (HLE) in this build, though it will be enabled in future releases. For now, you will need a PSX BIOS, either bios41a (I hear this is a great BIOS!) or scph1001.bin, but it MUST be named scph1001.bin (all lowercase) and be placed in the psx4gp2x directory where the psx4gp2x.gpe is.
- Save states may or may not work. Haven't tested them yet.
- Memory card in-game saves should work.
- Lots of stuff needs tweaking.

If you really want to see how things improved, play Buster Bros Collection from the previous release and compare it to this one. I was playing a very nice game with this latest build with sound enabled (sounded good!), no interlacing, and frameskip 1/2 and it was great.

Remember this is based on psx4iphone private beta v0.1.2 which is implementing my modifications to frameskip. Some games get graphical glitches or prefer a certain frameskip setting. If you see a flashing black screen glitch, just change the PSX Cycle and make it lower until it goes away.
You will also notice that even on really high frameskips, especially in 3D games, things dont go much faster and are still fairly smooth. This is due to the way these games are programmed. Not all frames can be skipped in the render process, so sometimes a really high frameskip in these games gives a slight performance boost but still keeps things smooth. Help me find out what settings should be default.

Here's a direct download link to psx4gp2x v0.1.2 beta/test 2:

Installation is the same as previous psx4gp2x releases. Fairly standard stuff, but since I dont have it all written out right now, I'll leave it to experienced users.

well a merry christmas to you, too

 

[zodttd]

heh

 

[senquack]

edit: Link works now, thanks

 

[hsinn3r]

Zod, the link's broken and your site doesn't have a link posted. I'm sure it'll be up soon enough, though

indeed. well a happy new year to you, too haha

 

[zodttd]

LOL oops. Fixed.
Hope someone tries it out. Wipeout XL runs really well too.

Heeell yeah ... Great job Zod. In next few minutes ill test tekken 3 / street fighter EX 2 and give some info how it worx.

20 min later:

Tekken 3 still unplayable [ even with messin in PSX Clock / Frame skip .... ]
SF EX 2 slightly better than previous versions [ i think ]

 

[zodttd]

I assume Tekken 3 will run pretty poorly, but maybe not. It runs fairly well on the iPhone. Not sure about SF EX2. For 3D games, you might want to try upping the frameskip to the highest settings after trying the defaults.

Interlacing still helps performance but degrades video quality. But since I'm starting to see some nice framerates, progressive interlacing might finally be an option again.

Disabling sound helps as well.

One thing I forgot in this version was in the in-game menu button mapping. This will be fixed shortly.

Very exciting, zodttd! I can't wait to try this version out!

Your hard work is VERY appreciated!

Santa Zodttd ????

I have to test tonight. Thank you!

 

[zodttd]

Ho Ho Ho! Merry psxmas!

 

[morrissey2k7]

Just out of curiosity, what changes were made to Test 2 (differences between Test 1 and Test 2, that is)?

Never mind... I just read "Edit 3" on your first post.

 

[zodttd]

Only difference is a quick fix for the in-game menu button. It now works by pressing volume-middle.

 

[Tobriand]

Sounds good. Will try and load a couple of games in the next couple of days. Defnitely want to see how Wipeout's running now. And of course, there's the obligatory FF games .

Thanks for a nice present, Zodttd

 

[zodttd]

Want to see something cool?
Try Final Fantasy 7 with the following settings:
PSX CYCLE: 1.1
PSX CLOCK: 20
FRAMESKIP 18/19 (note that it doesnt actually skip this many frames)

SOUND ON or OFF, INTERLACE ON or OFF. Depends if you want extra performance.

It runs super fast and super smooth! Battles are over 60 FPS, and in-game is at over 80 FPS.

Note that it takes awhile to boot FF7 if you dont change the PSX CYCLE right away.

I'm past the elevator in the first level and it's going at 100 FPS steady. This is accurate too. Moves silky smooth and fast @ 266MHz!

 

[jimmyslam]

What about watching it at 25FPS?

we dont need anymore... and sound could run smoother. right?


nice one zodttd.

i am looking forward to see wipeout runing smooth and fast .

 

[Jaylink]

Awesome Zodttd ^^ big thnx for this X-Mas present .

 

[morrissey2k7]

Could you please explain Cycle and Clock (what they do, in layman's terms) and how to change them?

It's one of the few things I've always been confused about with this emulator (but never got a straight answer out of anyone).

 

[-MB-]

I'm wondering, where are those cycle and clock options? I can't see any of these options in graphics/sounds menu. Also i only seem to be able to frameskip 17/18 not 19.

266mhz.. lucky devil.. My gp2x is one of the system that overclock to 250 and it crashes. One day out of sheer boredom, once my warentee is up I want to put some better cooling on it and see if I can get it to run a little faster.
