What is a G1E file?

G1E files mostly belong to Casio Education. G1E files serve two distinct roles. The main use is for Casio Graph 90 systems. These files hold data such as equations and graph settings. In many cases they are also known as Graphmatica equation files, indicating their role in storing mathematical expressions for graphing.
A smaller subset is used for game effects. In this context the files store visual effect data for game modifications, sometimes identified as Fire Emblem Effect Files. Tools like the G1E Viewer and Fire Emblem ROM Hacking Tools are used to access these files.

If your file originates from a Casio system, open it with official Casio graphing software or via the Casio Education portal (Casio Education).

If it is a game effect file, use a compatible G1E Viewer or a dedicated ROM hacking tool.

How to open G1E files

You need a suitable software like Casio Education to open a G1E file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your G1E file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a G1E file directly in the browser:. Just drag the file onto this browser window and drop it.
