All about JMA Files
The JMA file type is primarily associated with Jumper.
What is a JMA file?
JMA files mostly belong to Jumper. JMA files serve two distinct roles. Primary use: They function as Japanese animation sprite sheets. In this mode, the file stores a sequence of visual frames that game engines can render as smooth animations. This method is often used by gaming tools from companies like Jumper.
Secondary use: Some JMA files hold mouse configuration data. In these cases, the file contains settings and macro instructions for changing mouse behavior. Applications such as X-Mouse Button Control and KeyMapper use this file type. For more details on the software, visit X-Mouse Button Control.

JMA format details:
To view or edit JMA files you need to know the file format, because it determines how the data in this file is stored. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. If the file extension does not match the file format, double-clicking on the file will cause an error upon opening. Exact knowledge of the format is therefore important in order to solve problems occurring in files. In the following you will find our evaluation of the JMA files:
The JMA file extension is not widely used. Such a file is used by a few programs, each with its own file format. The two most popular formats are as follows:
- 50% of all JMA files use the same file format, which can be identified by the letters "ja" at the beginning. The contents of these files cannot be read by a human; only a computer program can interpret the data. JMA files can be up to 410 MB in size, but are often around 540 KB - 200 MB. This is an old file type which is rarely used today. The files contain the following words: 1000.jmp, 1001.jmp and 1002.jmp. Examples of file names are 001.jma or 001_001.jma.
- 30% of all JMA files have the same signature 34 12 AA FC. They consist of unreadable binary data. JMA files are between 10 KB and 10 KB in size. The file name 123.jma or mouse.jma is characteristic of these files. Files like these have the following tags: asdasd.
All other JMA files (20%) have no uniform format. Files like these are sometimes linked to isccp. You can get all the details of your JMA file by dragging it onto this page or by clicking the button "Choose your .jma file to analyze" above.
