BATTLE.BIN : - Find which units are active?
Fill a list of Unit of interest based on Preset Value. Unit should be Targetable worth of interest (see notes in code). This list is at 0x8019f3c4 + 0xc78 (1 Byte per unit)
------------------------------------------------------------------------------------------
Parameter : r4 = Preset Value 1 [0 = any unit / 1 = Enemies only / 2 = Allies only / 3 = specific unit / 4 = Unit in critical condition ? (see section))
r5 = preset Value 2 [0xff = ignore Acting Unit / if r4 = 0x3 r5 = specified unit ID]
Return : r2 = Nb Of Unit in List (AI 0xc78)
