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.
