In the 7800 emulator window, there are three different mapping (standard, left trigger, and right Trigger mappings).

You can toggle between while playing inside the emulator using the two trigger keys.

Normal mapping :

A          Fire 2
Y          L diff

B          Joystick

RTrigger mapping :

LOADING ROM FILES (.A78)

If you want to load rom images in the virtual drive of your emulator, you have to put your rom file (with .zip or .a78 file extension) on your GP2X SD memory in the 'roms' directory.

Then, while inside Atari 7800 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.

LOADING KEY MAPPING FILES

For given games, the default keyboard mapping between GP2X Keys and Atari 7800 keys, is not suitable, and the game can't be played on GP2X7800.

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 (.a78) 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.
