Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

@ matherp
The other day I came across a Video for the  Color Maximite 2+ and I so Love my CMM2s I'm gonna find one of these and collect every singe expansion card I can get, seriously this thing TRIPS MY trigger in a big way :) :) ! but the Big Takeaway wish from the CMM2+ is the Atari Joystick Port. I'm kinda Dreaming of 2 new Joystick commands that would make it easy to return joystick state. Maybe a Joyd that returns the state of the 4 direction buttons and 2 fire buttons  on an Atari joystick. and a Joya for the Analog Kraft type joysticks that would return a -255 to 255 value on the 2 pots and 2 fire buttons. and tie the commands to Specific Pins (Please make them grouped for a plug in cable)!I know this a Big Request but it would make a lot of things so Easy. it would make programming some Physical computing stuff possible for non programers like me

I have a Vision of a Joystick card that plugs in to 2X20 port on a picomite and passes through unused pins but adds de-bounce circuits etc..

sorry   if this looks like word Salad, But I Stuck at Writing and Typing
Thank you for reading this

I would suggest that if you want decent game control on a CMM2 that you get a WII Classic controller. They are far more useful than a joystick, plug straight in and the commands to read them are already built into MMBasic.

I know some people hanker over the Atari joystick (which is why I included hardware support for them in the PicoGAME), but they are terribly inefficient of GPIO pins, especially if you want more than one.

They are not quite as easy to handle in software as you might think at first (debounce messes up response time and you need to be able to read Fire (also debounced) at any time). The WII controllers have their own CPU to do the messy stuff and the latest CMM2 version can handle three at the same time IIRC.

Incidentally, you can also use a WII Classic controller on a PicoMite.
