Ok I just beat Alien Resurrection on hard mode, "whew", now I have a question. At the options screen when I select "RESEARCH", 16 small squares appear on the screen and when I select any square and press X the square turns bright green. My question is, which squares do I have to select and press X to enter Research mode, and how many different patterns of bright green squares are there that will do what?
