Here's a small update since I had some time over the last week to work on my v0 prototype. I've managed to program the prototype, though I haven't had any luck getting it to do anything. All signs point to the RP2040 being completely dead or inactive at best. Maybe someone out there could point...

Thank you for the feedback! Those are fair points, what I showed above just happens to be the pinout on an unmodified Pico. The analog and select buttons and the left analog stick are all supported, just not on a stock Pico without modification. The module PCB I developed supports the full...

I figure it's a good time as any, I'd like to announce this project to the forums. I've been working on this off-and-on for a few months now and figure it might be useful for a few folks here. Project Kunai is an open source emulator for Dualshock controllers using the RP2040 microcontroller...

Sony PSX Side Panels These are the plastic side panels found on the Sony PSX DVR. These parts do not appear to have an individual model/part number but the references were from a DESR-7000. In an effort to make these models more durable and friendly to 3D printing, I made some small changes...

I agree with Legend, the switching regulators don't have the best documentation, so you'd have to reverse engineer the controllers based off of what little information we have. The 5 V linear regulators are fairly simple so if you really need or want to reuse them, you certainly could. They're...

There's something called a "crowbar" circuit that can detect an over-voltage condition and quickly short, causing a fuse to blow. The wikipedia page on it gives much better detail and an example. I hope this helps.

Hello, just getting started with console modding. I have a love for retro consoles and a few years of experience doing hardware development and reverse engineering, so this should be very fun.
