You would need to have a third joystick if you wanted to use the left stick as a nunchuck joystick at the same time, though.You would not need a third joystick for this. You would just hook up your joystick on the right side of the portable to the Classic+ and it would use that to control the pointer on screen. You already need to hook up all your joysticks and buttons to the Classic+ for classic controller emulation. So, if you already have all that wired up, you should already be good to use this feature.
IR camera emulation uses the right joystick to control the pointer. Classic Controller already uses the right joystick but Nunchuk does not - that is why the pointer only works in Nunchuk mode.You would need to have a third joystick if you wanted to use the left stick as a nunchuck joystick at the same time, though.
Why would you reverse engineer an open source project? lolCan I still post in this forum @JacksonS and if so, where can I get a classic+ so I can reverse engineer it and maybe even upgrade it if I get any ideas. Btw I love your Wii SP 2.0, and am very interested in your PCBs so if you can remember it + have a chance can you tell me a list of parts for each PCB, and sorry about my ADHD making me talk to much, but if I didn't like your work I wouldn't even be talking to you, but as I said earlier I am absolutely fascinated in what you do and congrats on getting to MIT!
Everything is here https://github.com/JSnowden33/ClassicPlusWell since I'm mainly a computer science guy that wants to learn more about electrical engineering, I must learn all of the parts of his PCBs and how they work.
