4. LOADING HP48 APPLICATION FILES
   ------------

  I suggest you first, to read the manual of the HP48, because loading
  applications on this calculator is very complex !

  Usefull informations on how to install application for the HP48 can be
  found here : http://www.hpcalc.org/install.php

  You can save any HP48 files (with .lib or .48 file extensions) on your 
  PSP memory stick. Then, while inside the PSPX48 emulator, just press
  simultaneously SELECT+L to enter in the emulator menu, and then using 
  the file selector choose one application to load in the RAM of 
  your emulator.

  Back to the main emulator screen, wait few seconds, and press the Start 
  button of your PSP.

  + Library installation:

     If you have loaded a library file, you should see a line such as :

          Library 1262: ....

     To install it, you have then to press 0 then ENTER, then STO.
     After you have to switch OFF the HP48 (using Left Shift + ON), and
     switch it ON.
     If you go then to the library menu (Left Shift + 2), you should see
     now your library.

  + Program installation: 

     If you have loaded a program file, you should see :

       1: DIR
          ..... << .... >> 

     To install it, you have then to enter a variable name such as 'A' + ENTER
     then STO.  You can go to the variable menu (using VAR key) and then launch
     your program.

  You can find many applications and libraries on http://www.hpcalc.org/
