how to open pak or npa files???Please help

[RavenCloud]

I there,

it my first time here, so here is my question.

I am planin to make my own simulation game and I was searching through the net for material stuff. I found a lot but now I have all those nitro+ games and I really love their artwork.

I found some files in the net but not all cgs and not for all nitrogames.

Like is said ..I have those games and I installed them..everything works fine but there are these pak files where all the cg and voices are implented..how can i get them out of the pak files.

I want to use them.anyway to convert them or something like that?

Please I hope someone knows how to ^^

thanks in advance
