This is Team Plasma’s last stand. The key code would be impossible to figure out without knowing any Japanese. My code ended up being 9909. If you talk to the Team Plasma member that is southwest of the computer he will tell you a number. Use that number and 0 with a total of 4 digits. Examples: “9000″ “9900″ “9990″ “9099″ “9009″
etc. I defeat the Shadow Triad before going back outside to the Giant Chasm.
