Stella is the best emulator of Atari 2600 game console,
running on many different systems, such as Linux, Solaris,
Windows, MacOS/X WinCE, OS/2, DINGUX.

Dingux2600 is a port on Dingux of my previous GP2X-Wiz port version.

This package is under GPL Copyright, read COPYING file for
more information about it.

SD memory.

Put your roms files on "roms" sub-directory.

4. LOADING ROM FILES (.A26 or .BIN)
------------

If you want to load rom images in the virtual drive of your emulator,
you have to put your rom file (with .zip, .bin or .a26 file extension)
on your SD memory in the ´roms´ directory.

Then, while inside Atari 2600 emulator, just press SELECT to enter in the
emulator main menu, choose "Load ROM" and then using the file selector
choose one game file to load in your emulator. Back to the emulator window,
your game should run automatically.

5. COMMENTS
------------

You can write your own comments for games using the "Comment" menu. The first
line of your comments would then be displayed in the file requester menu while
selecting the given file name (snapshot, disk, keyboard, settings).


6. LOADING KEY MAPPING FILES
------------

For given games, the default keyboard mapping between DINGUX Keys and Atari 2600
keys, is not suitable, and the game can´t be played on DINGUX-2600.

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 rom file (.a26) then
when you load this rom file, 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.

7. CHEAT CODE (.CHT)
----------

You can use cheat codes with this emulator. You can add your own cheat
codes in the cheat.txt file and then import them in the cheat menu.

All cheat codes you have specified for a game can be save in a CHT file in
´cht´ folder. Those cheat codes would then be automatically loaded when you
start the game.

The CHT file format is the following :
#
# Enable, Address, Value, Comment
#
1,36f,3,Cheat comment

Using the Cheat menu you can search for modified
bytes in RAM between current time and the last time
you saved the RAM. It might be very usefull to find
"poke" address by yourself, monitoring for example
life numbers.

To find a new "poke address" you can proceed as
follow :

Let´s say you´re playing Moon patrol and you want to
find the memory address where "number lives" is
stored.

. Start a new game in Moon patrol
. Enter in the cheat menu.
. Choose Save Ram to save initial state of the memory.
. Specify the number of lives you want to find in
"Scan Old Value" field.
(for Glouton the initial lives number is 3)
. Go back to the game and loose a life.
. Enter in the cheat menu.
. Specify the number of lives you want to find in
"Scan New Value" field.
(for Moon patrol the lives number is now 2)
. In Add Cheat you have now one matching Address
. Specify the Poke value you want (for example 3)
and add a new cheat with this address / value.

The cheat is now activated in the cheat list and you
can save it using the "Save cheat" menu.

Let´s enjoy Moon patrol with infinite life !!
