4. LOADING ATARI ROM FILES
------------

If you want to load rom image in your emulator, you have to put your rom or
cartridge files on your SD memory in the ´roms´ directory.

The .zip, .rom, .atr or .bin file extension are usable with the Atari
800-XE/XL Rom menu. The .zip, .a52 file extension are usable with
the Atari 5200 Cartridge menu.

While inside Dingoo-Atari emulator, just press Select to enter in the
emulator main menu, and then using the file selector choose the rom or
cartridge file to load in your emulator.

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

In the main emulator window you can only load Atari 800 roms and Atari 5200
cartridge ... If you want to load other kind of roms or cartridge, please use
the "Original" Atari Menu menu (the white option in the emulator menu).

Then select "Cartridge management" then "Insert cartridge" and specify your
disk image file, then choose the cartridge type 5200 (for exemple), and go
back to the emulator using LTrigger.


5. 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 Defend or Die and you want to find the memory address
where "number lives" is stored.

. Start a new game
. 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 Defend or Die 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 Defend or Die the lives number is now 2)
. In Add Cheat you have now one matching Address
(for Defend or Die it´s 9E)
. 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 your game with infinite life !!

6. COMMENTS

line of your comments would then be displayed in the file requester menu while

emulator. The following parameters are available :

9. LOADING KEY MAPPING FILES
------------

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

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, save the keyboard settings
inside the emulator and have a look on file 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 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.


10. COMPILATION
------------

It has been developped under Linux FC9 using gcc with DINGUX SDK.
All tests have been done using a Dingoo with Dingux installed
To rebuild the homebrew run the Makefile in the src archive.


Enjoy,
