The BCR port was attractive to me because it is a port I wouldn't be
using for anything else. That is really the main reason aside from the
interrupts.
At least I figured as much, just wanted to point out the parport
solution is workable.
The idea was to use a microcontroller which would allow me to fit the
electronics inside the joystick body. I really only need a start bit
to get the CPU attention and then stream my switch states. That was
the idea, anyway. That is pretty much how the BCR would work, I would
think. Well, originally the thought was to duplicate the BCR and send
keycodes which could use the existing driver. But I am not sure if the
arrow keys would be included somehow. If so, it could potentially work
with any software that uses the arrow keys.
I think you should at least consider your original idea, as I think it
not only uses the often-ignored port, but it does so in an elegant way.
I did think about simply wiring into the arrow keys on the keyboard,
but I was trying to keep it external for community use.
Yeah, while I suppose it qualifies as "this is technically possible, so
it should be related", the invasiveness of it gave me pause.
