BATTLE.BIN : - Map_movement_decision/data_setting
Fill AI 0x3b4 Table - 1 Byte per Tile. If reachable (ON in AI 0xa74) Default data is distance to focused Target. Forced to 0x1 if there is a crystal (if needed)
Set potential destination, store best destination tile coordonates in AI 0xcc4
------------------------------------------------------------------------------------------
Parameter : Nothing
Return : r2 = 0x00 (Default)
r2 = -0x01 if routine Abort (Vsync call ?)
