KaktoR tests and takes care of the compressors and shares the versions I send to him.
I use variables S1, L1, etc so that the code is smaller and better visualization of most of the code in the Inno Setup interface. But each variable has its meaning in relation to what it does.
S1, S2, S3 = Temporary Strings.
FL = Flags per line.
FC = Flags count.
LN = Language Number.

In this GetFlagByLine function, if the number of parameters in FlagsByLine= key (setup.ini) does not cover all flags, the next lines will have the same amount as the previous one. The same is true in the GetFlagBoxAlign function.
Example containing 17 flags.
FlagsByLine=3,2,5
Results:
line 1 with 3 flags
line 2 with 2 flags
line 3 with 5 flags
line 4 with 5 flags
line 5 with 2 flags (3 + 2 + 5 + 5 + 2 = 17)

Look the test with my code in the attached file.
It avoids several errors due to lack of information that can happen if the user does not configure Setup.ini correctly.
It also only makes it possible to activate the BOX mode and no other keys are needed to create a square with the flags.

You should write some comments, the code I shared above do the same but imho its more concise and understandable I'm not good with naming variable but it still imho it does the job pretty well
I still didn't get why you used sqrt and other function
Will come back to you on tomorrow

It is used to calculate and create a square Box with the flags if FlagByLine key (in setup.ini) is empty or does not exist.

  if GetArrayLength(Result) = 0 then begin {If no results were obtained, it calculates the quantity to creates a square with the number of flags in the project.}
    FL := Trunc(Sqrt(LN)) + (Trunc(Sqrt(LN)) mod 2);
    SetArrayLength(Result, Trunc(Sqrt(LN)) + 1);
    for I := 0 to GetArrayLength(Result) - 1 do begin
      if FC + FL > LN then
        FL := LN - FC;
      Result[I] := FL;
      FC := FC + FL
    end;
  end;

This part adds only the numeral characters from temporary variable S2 to S3.

    S3 := '';
    for I := 1 to Length(S2) do
      if StrToIntDef(S2[I], 10) < 10 then
        S3 := S3 + S2[I];

This part avoids including a line with zero flags at the top (LangBox Top).

    if (S3 <> '') and (LN > FC)
    and ((StrToIntDef(S3, 0) > 0) or (GetArrayLength(Result) > 0)) then
    begin

If the flags of the lines informed in FlagsByLine remain, this part creates new lines with the same number of flags as the previous line.

  while (LN - FC > 0) and (FL > 0) do begin
    if FC + FL > LN then
      FL := LN - FC;
    SetArrayLength(Result, GetArrayLength(Result) + 1);
    Result[GetArrayLength(Result) - 1] := FL;
    FC := FC + FL
  end;

This part creates a new line with the remaining flags at the end.
It also removes an empty line of flags from the end of the box for the correct CENTER alignment.

  if GetArrayLength(Result) > 0 then begin
    if LN - FC > 0 then
      Result[GetArrayLength(Result) - 1] := FL + LN - FC;
    if Result[GetArrayLength(Result) - 1] = 0 then
      SetArrayLength(Result, GetArrayLength(Result) - 1);
  end;

See the example script I attached in the previous post.
Just change the values within GetValStr and SetArrayLength(Languages, 16).
