💡 What is a Hex Editor? schrieb:

A hex editor is a program that allows you to edit files at the byte level. It displays file contents as hexadecimal values. Free hex editors include HxD or Hex Workshop.

What Gets Changed?

In the BMP.exe file, there are hexadecimal values at one location that determine the game's start year. These values need to be changed to adjust the year.

The address is:

• 0BF68 (decimal: 49000)

Hexadecimal Basics

The hexadecimal system uses 16 symbols (0-9 and A-F) instead of the usual 10 in the decimal system. Years are stored as 16-bit values, with the bytes in reverse order (Little Endian).

🔢 Why Reverse Order? schrieb:

Computers often use the "Little Endian" format, where the lowest byte is stored first. The year 2025 (hex: 07E9) is therefore stored as E9 07.

Step-by-Step Guide

1. Create a Backup
First, create a backup copy of your BMP.exe file in case something goes wrong.

2. Open Hex Editor
Open the BMP.exe in a hex editor of your choice (e.g. HxD, as shown in the example image.)

3. Find Address
Use the "Go to" function (usually Ctrl+G) and enter the address 0BF68. You should see the bytes C8 07 there (for the year 1992).

4. Change Value
Change C8 07 to the desired value. For the year 2025, you need to enter E9 07.

5. Save and Test
Save the file and start the game. The new year should now be used as the start year.
