BATTLE.BIN : - AI_Initial_Targeting_Selection
Initialize Action Tables (used for priority scoring) - Choose AI behavior (might be non native based on Status) - Set AI 0x17fc (selected action)
------------------------------------------------------------------------------------------
Parameter : Nothing
Return : r2 = 0x00 Routine ends as intended
r2 = -0x01 Routine Aborts on V_Sync alert (memory variable is updated)
