To battle AJIM, you must have a time limit set (not on Death Match). Win the first one or two fights by gaining a health advantage and then letting the time expire. When an upward-pointing arrow appears over your next opponent as the round begins, AJIM will descend, destroying your erstwhile challenger and attacking. This will happen usually by the third battle. AJIM is very tough to beat, so pick your best character and hang in there. To control AJIM, you must challenge and defeat him as described (can't win by time-over). After beating AJIM, finish the game by completing all missions and destroying TANGRAM. Now, you have to set the clock in BOTH your DC and your VMU to February 15-30, 2000. Any month after Feb. is also fine, but AJIM is only available when your clock reads the last half of any month later than January, 2000. To select AJIM in any mode, go to the Random Select icon and hold both Turbos. AJIM will appear and can be chosen.
