BATTLE.BIN : : - AI_Target_Priority_Super_Routine_(001999c8)
Set Priority score for each reachable tiles and store it at AI 0x5f4 as a negative value (0 - AI 0x32)
------------------------------------------------------------------------------------------
Parameter : Nothing
Return : r2 = 0x00 Default value
r2 = -0x01 if routine Abort while looping (Seems to be tied to VSync_call - Update screen and com back ?)
