LOADING ZX81 PROGRAM FILES
------------

If you want to load program files in your emulator,
you have to put your file (with .zip, or .p file
extension) on your SD memory in the 'prg' directory.

Then, while inside GP2XZX81 emulator, just press
SELECT to enter in the emulator main menu, and then
using the file selector choose one program file to
load in your emulator.

Back to the emulator window, the program should stard
automatically.

LOADING KEY MAPPING FILES
------------

For given games, the default keyboard mapping between
GP2X Keys and ZX81 keys, is not suitable, and the
game can't be played on GP2XZX81.

To overcome the issue, you can write your own mapping
file. Using notepad for example you can edit a file
with the .kbd extension and put it in the kbd
directory.

For the exact syntax of those mapping files, have a
look on sample files already presents in the kbd
directory (default.kbd etc ...).

After writting such keyboard mapping file, you can
load them using the main menu inside the emulator.

If the keyboard filename is the same as the program
filename (.zip etc ...) then when you load this
program, the corresponding keyboard file is
automatically loaded !

You can now use the Keyboard menu and edit, load and
save your keyboard mapping files inside the emulator.
The Save option save the .kbd file in the kbd
directory using the "Game Name" as filename. The game
name is displayed on the right corner in the emulator
menu.


  Enjoy,

            Zx
