SD Gundam G Generation F Problem

[zicero]

I have a problem with this game.
While I'm playing the window of psx is freezed.
It heppens after I load the game from "load state" if I open the game from "File>>>CD Image" it says that I have to save a crash dump file after SONY logo ended
I still hear the game's sound but I can do nothing.
During freezing, in the dos window I see "read without driver"
(we have 2 windows right? one is game's window, the other is
dos window.)
What can I do?

These are the info about my labtop;

Window XP
Genuine Intel CPU T2400 1.83GHz
0.99 GB of RAM

I use pSX version 1.7 and also 1.6
This is my first time using pSX

These are the game info;

SLPS-02900 : SD Gundam G-Generation F [Disc1of4]
SLPS-02912 : SD Gundam G-Generation F [Disc1of4]
SLPS-02901 : SD Gundam G-Generation F [Disc2of4]
SLPS-02913 : SD Gundam G-Generation F [Disc2of4]
SLPS-02902 : SD Gundam G-Generation F [Disc3of4]
SLPS-02914 : SD Gundam G-Generation F [Disc3of4]
SLPS-02903 : SD Gundam G-Generation F [Disc4of4]
SLPS-02915 : SD Gundam G-Generation F [Disc4of4]

I don't know it's PAL or NTSC but it's Japanese version
I used ULTRA ISO to open the game.
(I'm sorry, I have no idea how to say, I'm not an English speaker person.)

I downloaded so many plugin file like;
scph1001.cdz
dbghinst.exe.
dbg_x86_6.6.07.5.exe.
and some bios that I have to place in system32 that file is something that ends with .dll
I don't have memory card, I saved in "save state"
and I don't have joystick too.

I try to look for my problem in this site but I found nothing.
If you have any solutions please reply this topic or if I miss some solutions in this site please let me know where it is.

Thank you in advance.
