Mouse Support for the Atari ST about blueretro HOT 5 OPEN

Alright, so I've updated to the latest firmware. I've done some more experimenting, and I have had some success, but not fully there yet.

First off I got the mouse to work with my PS4 controller. What I had to do first was set the right stick to Output 1, because the mouse is always plugged into the first port (Atari port 0). Then I had to set the directions in a complete reverse

Right stick left -> D-pad up
Right stick right -> D-pad down
Right stick down -> D-pad right
Right stick up -> D-pad left

Thats cause the mouse reads the directions as a normal joystick input, and the directions are reverse because the wheels on the inside are upside down. That at least got it to move in any direction. I then had to set Turbo for all directions to "1/2 Frames" to make it move at a slow pace. With all of that, the PS4 right stick could move the mouse on screen. And the buttons can be mapped to R2 and L2. So then what about a real mouse?

Well thats still not working all that great. With all of those settings as is, I can only get the mouse to move up and left directions. Down and right doesn't move at all. Changing the Max and the Deadzone doesn't seem to make any changes in that. What does change though is the Threshold, and only if you change it to 0% (as far as I can tell at least). Changing that does make all the directions move, but it moves in a very floaty way, and doesn't stop its directions with the move of the mouse. Changing the Turbo only seems to make it move more slowly at this point. It doesn't make it move any faster, which is still a bit of a problem. But the mouse clicks do work, so at least there is that.

So hey @darthcloud, does any of this make sense to you? I feel like I am starting to run out of options on how to experiment with this mouse. Do you have any suggestions or guidance? Thanks man.

There is no mouse support for 2600.

What you are doing is just mapping the mouse inputs as atari joystick buttons.

And that unlikely to work well.

Yes thats because the Atari mouse is plugged into a DB9M connector. Could you elaborate a bit on why it won't work very well?

from blueretro.

Its the same connector and pins but a different protocol, Joystick are simple buttons in parallel while a mouse use quadrature signaling.

BlueRetro doesn't support quadrature signaling. So it's not possible.

Ok, thanks for your reply. I guess my last questions would be with keeping the quadrature signaling in mind, would you have any idea why changing the Threshold to 0% would make such a drastic change for floaty mouse movements?
