Here is the problem: i want to make a psx game and i downloaded many programs but no one of them is for psx game making. Yes, i know that i need more than one program but i do not have any of them. I need only free programs because i dont have a money for shareware. So please give me answer for some questions:

1. Are there any free programs for psx game making ( modeling, animating)?
2. If the answer of 1st question is "no" which programing language do i need to make any program for psx game modeling. I mean the program which i use on pc to make a psone game.

PLEASE HELP!!!!!
