Change A7800Hawk's default peripherals to 2xProLine (from 2xJoystick)

[rcividanes]

The control configuration for Atari 7800 emulator only have a one button.
It's necessary to include more one button.
The original Atari 7800 control had two buttons

A new information.
I make some tentatives for configure the second button. In determinate moment I used a virtual control and press button power. In sequence I access the control configuration again and all buttons form Atari 7800 control appear.

Set A7800 > Controller Settings > Port 1 to "ProLine Controller".

ProLine should be default then, no?

[rcividanes]

Yes, ProLine is default, but, it's don't work in the first run.
I run EmuHawk and run the ROM and I configurated the control (only one button was available for config) .
So, I open another ROM for 7800 and I change default control for ProLine again. Don't work.
I try so many times and, magical, it's work. But, sincerely I don't know how.

After closing the settings dialog, your changes won't take effect until you load a rom (or reload the current rom). There's a reminder which appears in the main window, but it goes away after only a few seconds.
