It could be the regional thing. Like you're trying to play games from USA but using a PAL bios (for European games.)
Legally, PCSX2 requires you to have a PlayStation 2 for two reasons, one as a license to play PlayStation 2 games, and the other for you to dump the BIOS from, as PCSX2 requires a copy of the PlayStation 2 BIOS. Once you have PCSX2 running, however, there is no technical reason you need a PlayStation 2.

PCSX2 and it also requires the PS2 Bios
No.
While PlayStation 2 emulators like PCSX2 have gotten better about emulating the hardware, the firmware (BIOS) of the PlayStation 2 is very unique. It takes time to reverse-engineer all the system calls that games make to the BIOS, so there is currently no drop-in replacement for the real deal.
You could either dump the bios yourself, which could take a little patience, or download from the link below. Note that the only LEGAL way of obtaining a bios is dumping it from your OWN Playstation 2 console.DO NOT ask where to get the bios in the PCSX2 forum, because it's against the rules. That's because the ps2 BIOS is a copyrighted material of Sony and that makes its distribution illegal, meaning we could get in trouble if it was found out that we were supplying people illegally with bios files.Getting the bios needs to come from your machine according to copyright protections. Procedures can be found at the link for the best emulator the PCSX2. PCSX2 is a Playstation 2 'emulator', a free program that tries to replicate the Playstation 2 console to enable you to play PS2 games on your PC. If you do not have the skill to even download bios think about forgetting PS2 emulation. It will not be like playing a PS2 and instead is a lengthy and time consuming process. See the PCSX2 home site and try the getting started link. or the other link for the guide and under the guide bios configuration section there is a link for "A new Bios dumper is already available that can dump your PS2 Bios,ROM1,ROM2,EROM and NVM. Get it HERE"
No. PlayStation 3 games will obviously not run natively, and as of 2010 there are no functional PlayStation 3 emulators.
It's more about bragging the PS2 games are not easy to play and considerable time is spent setting up your PC for each game. There is a guide for running the emulator and it has been added as a related link. Of course a PC can not play PS2 games without an emulator programThe emulator PCSX2 does not contain a PS2 bios which you need to get from your PS2 and move to your PC or see quote from related link:" In the third screen, you will be prompted to select your BIOS image from the list. If you can't see anything on this list, you need to either copy your BIOS files in the folder seen below, or change that folder to point to where you have your BIOS image saved. For more information about the BIOS, check the BIOS configuration section of this guide. If you can't make a selection, you will not be able to use PCSX2"
BIOS stands for basic input-ouput-system and it is how the machine reads and parses data
PlayStation BIOS dumps are not legally redistributable. You must dump them from your own PlayStation.
It is actually not as hard as you would think. Refer to: http://forums.ngemu.com/pcsx2-forum/84994-guide-dump-bios-through-usb.html for directions to dump your PS2 bios onto a USB Flashdrive. And on a side note, when you dump your bios using a custom code (as explained in the above link) you are actually copying your bios, so it does not render your PS2 useless.
u can download it on net
