What is a CGB file?

CGB files mostly belong to Game Boy Emulator. Primary Use: CGB files are mainly Game Boy Color ROM images. These files contain binary game data extracted from a Game Boy Color cartridge. They are used to run games on emulators that mimic the original hardware.
Other Usage: A number of CGB files are also formatted as CityEngine Compiled Rule Packages. In this form, they hold procedural rules that are applied in 3D urban modeling. Such files work with Esri CityEngine software. For more details, visit the Esri CityEngine overview page.
Key Details provided by FilExt.com:

The file stores compiled binary data rather than plain text.

Game ROM images require a Game Boy emulator (e.g., BGB, VBA-M) to run.

CityEngine rule packages are interpreted within Esri CityEngine to generate city models.

Opening and Viewing: Determine which usage applies to your file. Use a trusted Game Boy emulator for game data, or launch it inside Esri CityEngine if it contains procedural rule data.

CGB file format details:

The file format, which is the arrangement and type of data in a file, determines which program can open the file. The file format can be determined based on the file extension and the signature (the first few characters of a file). If the file extension or signature does not match the file format, errors will occur when opening or editing the file. When there is a problem with a file, the first step to solving it is to determine the file format. In the following you will find our evaluation of the CGB files:

CGB is seldom used as a file extension and includes a lot of different file formats for different programs. The two most popular formats are as follows:

• 15% of all CGB files use the same file format, which can be identified by the letters "ioñ¹9' " at the beginning. These are binary files, so they do not contain words or text. The files are 4 MB to 7 MB in size, with a median of 7 MB. The file name data.cgb is characteristic of these files.
• 8% of all CGB files start with the bytes Êþº¾, which are crucial for this file format. These files are binary files, so they do not contain text, but only cryptic characters. The average file size is 97 KB with most files being between 13 KB and 140 KB in size. The following keywords are characteristic: SourceFile, esri, java/lang/Object, Lcom, rules and CityEngine. These files are often associated with building.

All other CGB files (77%) have no uniform format. These files sometimes refer to pporg, hero, reshiram, zekrom, gear, zoroark or carte. You can get all the details of your CGB file by dragging it onto this page or by clicking the button "Choose your .cgb file to analyze" above.
