Beta release for Atari 7800 joystick adapter firmware

7800
We just released a beta firmware that supports 2 button Atari 7800 joystick. This joystick has a pretty odd design that permits to support 2 button mode in 7800 machine but keep compatibility of 1 button mode in 2600 machine.

Firmware: Atari_7800_v2.1.hex
