What is a .GBM file?

The file extension .GBM stands for Gameboy Map File. This type of file is specifically created using a program called Gameboy Map Builder, often abbreviated as GBMB. This program is designed for people who want to create maps for games that are played on the Gameboy console.

A .GBM file contains important information about the map you are creating. This includes the dimensions of the map, which are measured in tiles (small square pieces that make up the map), and the number of colors that can be used in the map's properties. Additionally, the .GBM file links to a .GBR file, which is a tileset file. The tileset file contains the visual elements or tiles that you use to visually construct your map in the Gameboy Map Builder program.

To open and work with a .GBM file, you need to use the Gameboy Map Builder software. This is the primary program used for creating, editing, and saving these map files.

Here’s a step-by-step guide on how to create a .GBM file using Gameboy Map Builder: 1. Open the Gameboy Map Builder program. 2. Start a new map project by selecting "File" from the menu, then "Map properties...". 3. In the map properties, you can set the size of your map by specifying the width and height in tiles. 4. Choose a .GBR tileset file. This file contains the tiles that you will use to design your map. 5. After setting up your map properties and selecting your tileset, click "OK" to confirm your settings. 6. You can now design your map by placing tiles onto the map grid. 7. Once you are satisfied with your map design, go to "File" in the menu, and select "Save" or "Save As..." to save your work. 8. Name your map file, choose where you want to save it on your computer, and then click "Save".

By following these steps, you can create your own custom maps for Gameboy games using the Gameboy Map Builder software.
