I originally made vAtari because the GP32 was sorely missing a good Atari 2600 emulator and as it happens so does the Dingoo A320 in Native mode.
The original version of vAtari for the GP32 was entered into the PACC 2010 contest. It didn't win but it did provide excellent motivation to get most of the work on it done.
Since then, this version has many fixes and enhancements including more accurate graphics and sound and higher compatibility.

The Dingoo A320 is my first .SIM release so there is no frontend end: it uses the Dingoo Native's OS to select a ROM.

The GP32 version has a frontend: select a game and press either 'A', 'B' or 'Select' to start the game. The button you press to start determines the GP32's CPU clock rate.

In both cases, the Atari 2600 ROMs should be uncompressed and have the .A26 suffix.

* Joystick provides movement for either joystick or paddle.
* 'A' Button is the fire button.
* 'B' Button is the fire buttons on the "other" controller.
