+The paramater map can be used to specify different address maps. This is currently only used in the NDS core where address map 7 is used for the ARM7 address map and 0 and 9 are used for the ARM9 address map. The default address map is 0.

 # /input command
 
 Sends an input to the emulated system which will stay until a different input command assigns a new value. The parameters specify the input to set and the value to set it to. In general all inputs that have keybinds in the GUI can be set using this command. A full list of the valid input names and their current state is viewable with the /status command. An arbitrary number of inputs can be set using this command. Returns "ok" on completion.
