@Shuna Tempest

Let's start from the beginning as if we hadn't yet tried anything.

Please list the Sim's Names as you want to see them in your game, their gender, and zodiac (star) sign for each. Then also attached the images they are to use. Next I will create a version of the MySim.dat so you can test them yourself. If that works then we can continue learning how you can add more of them (if there any additional you will want).

Beginnen wir von vorne, als hätten wir noch nichts ausprobiert.

Bitte listen Sie die Namen der Sims so auf, wie Sie sie in Ihrem Spiel sehen möchten, ihr Geschlecht und ihr Sternzeichen. Fügen Sie dann auch die Bilder an, die sie verwenden sollen. Als Nächstes werde ich eine Version von MySim.dat erstellen, damit Sie sie selbst testen können. Wenn das funktioniert, können wir weiter lernen, wie Sie weitere hinzufügen können (falls Sie weitere möchten).

Ok machen wir so nehmen wir Maria Weiblich Sternzeichen Fisch und dann nehmen wir Isis Weiblich Widder ich hoffe das reicht erstmal für den Anfang weil wäre gut wenn ich dann endlich weiß wie man es macht

Ok, let's do it like this, we take Maria Female Zodiac Sign Pisces and then we take Isis Female Aries, I hope that's enough for now because it would be good if I finally knew how to do it

That's perfect as I do hope to teach you the method.

What we want to do first is make our test isolated from all previous MySims testing. To do this (with the game not running) we want to rename the MySim folder to something else. I renamed mine to MySim - Original. Then we want to create a new, empty MySim folder.

Next download these three files into the new MySim folder:

• MySim_Isis.bmp
• MySim_Maria.bmp
• MySims.dat

It should look like this:

 

I forgot to ask if you use the MySimtropolis_Rulez.dat file, but I'll assume yes for this next part. Run the game and see if you can select your MySim:

^ We expect to see only one at this point.

If you are not using the MySimtropolis_Rulez.dat file, then you should see the 21 default Sims and will need to scroll to page 2 to find Maria. Either way, let me know how it goes.

Assuming that went as expected, close the game then open the file MySims.dat in HxD. Paste in the following numbers in the left-hand panel at the end of the existing numbers. They will show up in red.

Numbers to paste: 04 49 73 69 73 00 03 0A 4D 79 53 69 6D 5F 49 73 69 73

How they will look in HxD:

Save the file.

Run the game and look in the MySims selection panel:

 

If this all goes well, we can work on adding another of your choice with you doing more of the work.

@CorinaMarie Ja es hat geklappt und auch ich konnte sogar die Personen die ihr in my simtropolis erstellt habt hinzufügen in dem ich diese kopiert habe. nur jetzt was muss man wenn ich zb noch jemand hinzufügen möchte auch einen selber erstellten dann noch die frage die drei punkte Geschlecht Sternzeichen und der dritte punkt was gebe ich in dem dritten punkt ein ? da weiß ich nicht wie das geht und nein diese  MySimtropolis_Rulez.dat hatte ich nicht verwendet und mir werden die Standart-Sims angezeigt 

Cori Edit: Added Google Translation:

Yes, it worked and I was even able to add the people you created to my Simtropolis by copying them. But what do I need to bear in mind now if I want to add someone else, for example someone I created myself? Then the question is the three dots gender star sign and the third dot what do I enter in the third dot? I don't know how to do that and no, I didn't use this MySimtropolis_Rulez.dat and the standard Sims are displayed. So now I've tried again to make my own Sim and add it and it doesn't work, what's the mistake, am I doing it as shown in the pictures? Or is it the 3 dots after the star sign where I'm making the mistake?

That's where it needs to know the length of the text which follows the third dot. And the text that follows is the name of the BMP image file. So when it is MySim_Maria we count all the spaces taken and see that is 11 characters. We must convert that to hexadecimal so the value in the file is 0B. The third dot for MySim_Isis is 0A to indicate that is 10 characters long.

Here's a full recap of the MySims.dat file structure:

• File Header  (4 bytes)
• (Variable length data for MySim # 1)
  • MySim name length value  (1 byte)
  • MySim name text string  (variable # of bytes)
  • Code for Gender  (1 byte)
  • Code for Zodiac sign  (1 byte)
  • MySim bitmap file name length value  (1 byte)
  • MySim bitmap file name  (variable # of bytes)
• (Variable length data for MySim # 2)
  • MySim name length value  (1 byte)
  • MySim name text string  (variable # of bytes)
  • Code for Gender  (1 byte)
  • Code for Zodiac sign  (1 byte)
  • MySim bitmap file name length value  (1 byte)
  • MySim bitmap file name  (variable # of bytes)
• (Variable length data for MySim # 3)
  • MySim name length value  (1 byte)
  • MySim name text string  (variable # of bytes)
  • Code for Gender  (1 byte)
  • Code for Zodiac sign  (1 byte)
  • MySim bitmap file name length value  (1 byte)
  • MySim bitmap file name  (variable # of bytes)
• (Etc.)

And remember, all the info in the left-hand side of HxD is hexadecimal values.

If you use the Spreadsheet in the 2nd post of this topic, it'll figure out every bit of that and then you can copy the entire string of hex numbers.

Also, remember the image file needs to be BMP format. JPG and any other will not work in the game.

@CorinaMarie Ja vielen Lieben Dank ich habe es endlich geschafft, mein Fehler lag die ganze zeit in Punkt drei nach Geschlecht und Sternzeichen. Aber jetzt habe ich es geschafft vielen lieben dank. Und danke für die mühe.

Yes, thank you very much, I finally managed it. My mistake was always in point three, gender and star sign. But now I've managed it, thank you very much. And thank you for the effort.
