Encounter an error while trying to play game on rpcs3.

Well, there's your problem. You're trying to run God of War 3.
If you haven't already, read the FAQ.

But I have seen I lot of videos of people playing different games through rpcs3 , one of which I had, was playing Uncharted 3 on his windowsXP,I mean direcx 9, and it also worked smoothly and now I have windows 10 havig directx 12, so I can give a try to play games like that.

I didn't told you at the first place that I was paying God War 3 as I was scared, that you will not help me.

So can you please tell me the settings and methods to play any games like that on rpcs3. Please.... It's a request.

It would be very helpful of you.

Uncharted, God of War won't work. The videos you likely saw were fake.
Windows XP is not capable of running RPCS3. We have never had a DirectX 9 renderer, and never will.
Maybe in a couple years you'll be able to get into menus for God of War at like 10fps.
And as I already linked you before, all the playable games are listed here.
And you can probably see, that all of those are simple 2D games.

I read what you said also I've seen the list, I saw a video yesterday in which this guy made a game supportable called Arkedo Series - 02 Pixel (which is not in the list of supported games) using PSN (or something like that I don't know what it was), then what you will say about that.
And I do knew the difference between a real and fake video, the guy who run rpcs3 on xp,I downloaded that video like maybe a year ago or more than that. And maybe he changed some settings or something and run game in low quality or something like that, as it was a 360p video that's why I said that.
Even if I say in the earlier versions of pcsx2, it was normally to select the iso of game one want to play, not like only 2d games are playable, then why that happened at first place.
At least tell me how I can run those games on rpcs3, there must be some settings and methods, and also setting with which game run fast, even after that if game runs slow, it's all on me.
Please at least help me......

Ok. I'll give you a small tutorial how to get the games and how to run them on RPCS3!

What you need:

• PS3 with Custom Firmware installed
  
• The game disc (you can also get the game, if you purchased through PSN, but it's harder and I don't know how to do it that way, but you should be able to use Google)
  
• FTP server on your PS3
  
• A FTP client on your computer
  
• Have your PS3 connected to your computer or network
  

What you need to do:

1. Turn on your PS3
   
2. Insert the disc into your PS3
   
3. Start the FTP server on PS3
   
4. Use the FTP client to connect to your PS3
   
5. Copy the contents of /dev_bdd0/ (or from /dev_hdd0/game/GAME) to your computer
   
6. Put the game into RPCS3's /dev_hdd0/game/
   
7. Open the game in RPCS3 and wait for it to crash!
   

Over two years ago RPCS3 dropped the support for 32-bit Operating Systems, due to their limitations at emulating the PS3.
But like sshadow already said: How gullible can you be?
And yes, Arkedo Pixel runs with LLE. It's in the half-playable section though, due to it not being confirmed to be completable. You can see the requirements for the different categories here.
