Please, stop posting multiple things on the same topic in the future. It makes it hard for us (we do not know which one to reply to), and also makes it hard for you (harder for you to find out which one we reply to).
If you don't have a 3D card then the only thing you can do is use a software plugin. However this won't look so great, so unless you decide to buy a video card the best thing to do is play your PSX games on your PS2.
and as kairi00 said, please don't start many threads about the same question.
