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.
