Personalizing Open Source Software and OpenMPT in particular

[Newbie]

Hello, can someone, perhaps Saga Musix, please tell me where the following is in the source code for OpenMPT, sorry for starting another topic, when I posted this it didn't cross my mind to post it as a reply in the old topic.

and on the left side of the about screen beside the image there is the following:

OpenMPT amd64 (64 bit)
Version 1.29.11.00

https://openmpt.org/


So the reason I want to know this info is because I am compiling a personalized edition of OpenMPT that I want to call "Clef Tracker" or something like that and I will give it new about screen graphics and a new splash screen.

So this is how I want it to look in the about screen:

I would like to do this because I want to create my own personal fork with my own personalizations. So why do this? Why not do it, it is a learning experience and it is fun.

I installed Visual C++ 2019 and compiled OpenMPT as is and came to the realization that I can personalize any Open Source software, so why not attempt to do it, I could do the same thing with LMMS, Musescore, Audacity, Gimp, Inkscape, Fontforge and many others. And maybe I could learn to modify other things as well and also add features..... now I'm dreaming because although I learned Turbo Pascal in High School, I was not very good in it, but a person can dream.

I realize that none of these things are necessary for a personal fork but I want to do it anyway.

[Saga Musix]

As I mentioned before, searching for the text you want to customize is always the first step. There's really no point in telling you where to find it because you don't learn anything from it. So here's a hint: Part of the license text that you want to change is for example "Copyright (c) 2004-2021, OpenMPT Project Developers". Open the source code in Visual Studio and do a global Find & Replace action by hitting Ctrl+Shift+F and pasting that text there. You will then find the text and can modify it. The text itself is return from a function called "GetLicenseString". You can again apply Find & Replace on that function name to find all the places in the code where the function is called, which helps finding the code where the about dialog is created.

[Newbie]

Thank you Saga for that hint, by the way are you from Germany, I'm asking because I'm hearing of massive catastrophic flooding in Germany and Belgum, if so how is the situation where you are?

[Saga Musix]

It's fine in this part of Germany, thanks for asking.

[vananaBanana]

Hi,

What kind of features are you implementing with your fork?

Cheers,

Maxim
