jnostromo provides drivers for the Razer Nostromo designed to be E-Sport legal. Profiles are unique user-defined keymappings and can be created for each game. A profile can have up to eight unique keymaps with mappings to switch between keymaps. jnostromo includes an easy-to-use configuration GUI to map keys from the nostromo to the keyboard and/or mouse. The configuration GUI can be hidden, and, at any time, the GUI can be displayed by clicking on the system tray icon. It's the goal of this project to make jnostromo the driver of choice for E-Sports and competitive gamers.
