Controller mapping

[jotego]

Since a few weeks ago, MiST sometimes maps the only USB joystick I have connected to the second player. I have to unplug and re-connect, then it gets mapped to the first player.

There is also this issue I got, where they found that the controller order for joysticks 3 and 4 is somehow messed up in my cores.

I checked my code and I swap joysticks 1 and 2 (0 and 1 in user_io) when I instantiate user_io. But that works to be the right assignment -at least most of the time.

I don't understand why I have to swap them. I saw that the PC engine core has an option to swap the two joysticks too.

What's going on? Is the joystick order influenced by something else? Should I swap joysticks 3 and 4 too? Do you have some insight on this topic, please?

Swapping 0 and 1 is historical. More details here:

I'm not aware that 2 and 3 must be swapped. Maybe it's a hardware issue during enumerating the controllers. 4 controllers can take a lot of power, and one of them might glitch. Or there might be other USB errors. Hard to tell without a debug log output.

Thank you for your explanation :-)
