Shadowfire

He just ported what was on the BBC, and that included the analog input.

Because, as we know, And the SID chip has the analog registers for the 1351 mouse and the pedals, but only a few games actually use those analog registers for analog joysticks, which would be REFs, Flight Simulator 2, and Shadowfire.

And

some breakout clones.

So it's not especially designed for analog joysticks.

But of course, if you could, you could use analog joysticks to mimic the paddle movement, right? That is probably what you are thinking about.

But Refs and Shadowfire... especially let you select analog joystick as an input device but Shadowfire on the other hand is special because we spoke about it it also supports light pan and other rarely used input devices.

Like, oh, there's another input device.
