    current project I'm working on, hardmoding with a pi zero and adding a power switch wired to battery. The pi zero is small enough to hide inside or tape outside with a xl. Built in wifi would allow ssh directly to nand read/write. This would be useful for developers. You can remotely enable USB device mode to dump that way or ftp transfer. This way you don't need a pc at all and direct read write to nand with hardmod. Again this is of no real use to non developers.

    Everything is ready to be installed just contemplating on where to place it. Also the hdmi and USB ports have been ripped out. There's a way to power the pi zero through batter power I used those diagrams.

    Have you considered connecting the nand directly to the raspberry pi? As in without the sd card in-between.

    Yes there is no sd in between. That pic is a diagram so that you achieve max speed but are required harmodding the rest of the pins. Most people just do the 4. It's 4 flat cables directly soldered to pi.

    This would be great for people with broken PC's with only one USB port like me

    since pi's are good at multi tasking, you can also solder some of the pins up to the button test points and add a gc controller input (using a modified plug of course.). mine is using an arduino and is almost done.

    great idea! im thinking a wireless wavebird? need to rip apart teh reciever and see how small it is on the inside. i love small dev boards. i just wish the 3ds wasnt as locked down os wise we could do so much more...

    you have an image of that chip with a quarter in it? i need something for scale. an ATtiny and that chip might fit, but it would need an extended back plate. I know someone sells ones that match the color of the inside of a 3ds, but i dont remember where.

    If it's too big you can always use this and attach a GameCube port to plug in the wavebird receiver to the outside also letting you use any sort of input really. Or you could wire this to the pi and then connect Bluetooth controllers the the 3ds as well. A little extensive but I push limits.

    that chip would acctually just make it harder. it would be simpler to just directly connect the wired from the controller to the gpio ports. i have code for the arduino for it but i can rewrite it in python.

    That chip is so u can use other controllers including Bluetooth ones. But it can probably be wired directly to the pi as well and share Bluetooth connections

    alright. ill need new code to change the usb output to pulses for buttons, but its definitely do-able. now, would it be better with the rasp-pi zero or an arduino?

    Pi zero arduino is smaller but think of the possibilities with a full custom firmware like for psp. Pi zero can do way more it's a soc as opposed to a dev board

    This is really cool! Can you take pictures once everything is up and running? Would be really nice to see it.

    Yes soon need to find the perfect placement of the board it's half the side of a credit card

    zero it is ;) ill start working on that code. also, It would be possible to 3d print a back plate with a few more millimeters of space. I found the plans for it.
