User 3/4 not possible?

Is it possible to use 4 joysticks? I can't get 4 Switch Pro controllers to work - Retroarch sees them but the Atari only sees joysticks 1 and 2.

I believe the answer to this is no, because this library is using atari800 3.1 code instead of 4.1. There are enough changes in the atari800 directory in this module compared to the ATARI800_3_1_0 tag of atari800 that it's unclear (to me) the best path for upgrading to 4.1. In a perfect world, whatever changes this needed would be made directly in the atari800 repo as a submodule, even if that's on a branch or fork...

You can now use four controllers if the machine type is set to 400/800 (the only Atari 8 bits to support four joystick ports). Change was merged in #27
