What is a G1M file?

A G1M file is a data file saved in the G1M format used by various Casio graphing calculators, including fx-9860G, fx-9860GII, and fx-CG series calculators. It may contain various types of data, including an entire Casio Basic or C.Basic program or a single spreadsheet. G1M files are typically stored in the storage or main memory directories of a graphing calculator.

More Information

G1M files are most commonly used by older Casio graphing calculators from the 2000s and were replaced by G2M and .G3M files in newer versions of Casio graphing calculators. Since the files are not meant to be manually opened, you most likely will only encounter the files when transferring data files from or to the storage or main memory directories of a graphing calculator.

The Casio FA-124 program allows you to transfer G1M files to your computer from a graphing calculator. The fx-Manager PLUS Subscription and fx-CG Manager PLUS Subscription programs also allow you to emulate fx- and fx-CG series calculators and open G1M files.

A G1M file may also be a 3D model used by a Gust video game. Typically, it contains a skeleton and mesh used to show a character or object in-game. However, some G1M files contain only a skeleton, while others contain only a mesh.

More Information

Gust is a division of video game developer Koei Tecmo Games. This division develops various role-playing game series, including the Atelier, Surge Concerto, and Nights of Azure series.

The RPGs Gust develops use assets saved in many proprietary file formats, including the G1M format. Different games may use different versions of the G1M format. For example, some games may store a skeleton and its associated mesh in the same G1M file, while others may split that data into several separate files.

Most players will never encounter or need to open a game's G1M files. However, modders interested in changing characters' and items' appearances may want to edit, convert, and/or replace a game's G1M files, using player-developed modding utilities.

How to open a G1M file

You can open a G1M file with Noesis (Windows), with the Noesis G1M/G1T/G1A Importer or ProjectG1M plug-in installed.
