In script.iss search for

procedure SystemReq();

I used functions from ISSysInfo.dll from peterf1999.

I can't explain all of this to you.

Some example from the code

if (GetCpuMaxClockSpeed) < Processor then begin
    CPUNameLabel.Font.Color := ColorConverter(GetValInt('SystemRequirement', 'HWNotOkLabelColor', 0));
    CPUNameLabel.Caption := 'CPU: '+IntToStr(GetCpuMaxClockSpeed)+' MHz,' + (ExpandConstant('  {cm:DirectXNeeded} ')) + '{#Processor}'+' MHz';
  end;

GetCpuMaxClockSpeed
Get max clock speed of your CPU. You find it by default in ISSysInfo.iss

Processor variable takes info from {#Processor} ISPP (which you can find in Settings.iss, which reads input directly from Settings.ini).
So if detected CPU max clock speed is lower (<) then Settings.ini input, label (HWNotOkLabelColor) is in red color (default). In fact you can change the color of HWNotOkLabelColor label in Settings.ini (this is also a ISPP). The ColorConverter only change color codes from BGR (Blue, Green, Red) to RGB (Red, Green, Blue). Inno's standard is BGR, which I find not really good.

CPUNameLabel.Caption is just the label for CPU.

'CPU: '+IntToStr(GetCpuMaxClockSpeed)+' MHz,'

However you have to convert the CPU MHZ number from integer to string (IntToStr) to display MHZ correctly.

(ExpandConstant('  {cm:DirectXNeeded} '))

Don't get confused here. This is just a custom message for the word "Required", but I was too lazy to change it to something more accurate lol.

'{#Processor}'+' MHz'

Display your input in Settings.ini for Processor= and add MHz after this.


Most of the other parts from the 'procedure SystemReq' are just variables or text/labels/fancy stuff which is not really needed but it looks better

I always tried to made the scripts as clear as possible to give a fast overview, eventough everybody works a bit different and has a bit different characteristics.
