Just a a couple of games, age of methology the titans, and lotr bfme2. and few others. also i am new at this as well, but i can open them in text pad, it just comes out as random letters, and numbers where can i get a disassembler?

first off i would like to announce this is my first time on here, i would like to know what kind of programs i need to edit my Pc games. i have been learning how to edit with just texts but i would like to know what i need for the text scripts i can't read? any information can help--thanks
