Hello everyone! I am Redux, and I am pretty new to the BitBuilt forums. I am super excited to start working on this project. I have been toying with the idea of building my own portable Wii for a while, but I recently decided to commit and start working on it. There are a couple of goals I want to accomplish with the project
  • Just get it to work (It is my first portable, after all)
  • Include MX Chip, Bluetooth, and IR sensor functionality
  • 3D printed case design based on the Classic Controller Pro
  • Use original Classic Controller Pro parts
  • (Possibly?) Redesign the ZR and ZL buttons to make them analog triggers
I started this project by buying a black Wii on OfferUp for $20. It seemed good, and I was able to power it on and install RVLoader. I also bought an RVL-PMS-LITE, a PMS-PD-3, a GC+ 2, a U-AMP 2, and a 5-inch screen with the driver board from 4 Layer Tech, along with some cheap AliExpress components like speakers and buttons.
I opened up the Wii and ohhh no, it's filled with dead cockroaches.

I decided to call this portable project La Cucaracha upon this discovery. After cleaning up that mess, I was left with a bare Wii motherboard. I prepared the Wii for trimming by tracing the OMGWTF outline and removing some of the components in the way. Like the true delicate craftsman I am, I managed to rip up the trace to one of the video output capacitors while removing it. I just stuck it down with kapton tape for now, but if anyone has a better idea of what I should do about it, let me know.

I then cut up the Wii with my Dremel, and sanded it down to a nice smooth edge. I tested the resistance values, and they all looked normal. The below images are of the initial rough cut before sanding.

I then started to test the Wii by wiring up the PMS lite to the trimmed Wii, and a battery holder to the PMS lite. I also attached the PMS-PD to the PMS to use the power button and to charge my 18650 battery cells since they were a bit low. I cut up an old RCA cable to get composite video out, and she lives!

I plan on testing USB and GameCube controller functionality, and relocating the MX chip and the Bluetooth module later, along with starting work on the case design. Updates will probably be a bit slow for now since it is finals season at my university. I am super excited to work on this project, and I want to thank everyone who gave me the inspiration to start working on this. I want to give a special thanks to Wesk for providing a 3D scan of the Classic Controller Pro, as I will base my case design around this scan.

Hey congrats on the trim! I'm actually doing a design based around the classic controller as well! I like the handles of the pro but I want the triggers of the classic. So mine is currently using a classic controller. Can't wait to see how yours comes out!
