# ROUTINE: TRY GET UNIT MISC DATA BY UNIT ID
# Parameters:
# r4 = (ptr_UnitID) Pointer to a Unit ID (for events?)
# Referenced value is overwritten by the corresponding Unit Misc ID, if:
# (*ptr_UnitID) != 0) and (*ptr_UnitID) < 0x100, and misc unit was found for the specified ID
# r5 = (ptr_State) Pointer to write state value to
# State = (*ptr_UnitID) - 0xFE, if (*ptr_UnitID) > 0x100
# 1, if (*ptr_UnitID) == 0
# 0, Otherwise
#
# Returns:
# r2 = 0, if (*ptr_UnitID) != 0) and (*ptr_UnitID) < 0x100, and no misc unit could be found for the specified ID
# = 1, Otherwise
