That signal is GND

Sorry, I don't think I typed this very clearly. What I am saying is that thedrew has accidently made this a voltage plane instead of a GND plane (as you have pointed out) hence the lighter colour. Either that or its just filled weirdly on kicad/his output design.

He made that GND, it's not a lighter color than the ground pour

I've been currently doing my own board design so this does not bode well....

Sorry if I'm incorrect here, it's difficult to tell from the Kicad pictures, but I would double check this plane here as it looks like it might be a voltage plane instead of GND where the vias are connected too (light green instead of the standard dark green fill across those traces).

Out of interest what stackup did you use with JLC? What was the prepreg thickness? Did you try changing out the terminator resistor for different value on the ram?View attachment 26191

Yes that is ground. I guess it squeezed its way in between those traces once I drew the GND plane. Probably does no harm though. I haven’t experimented with changing the RAM resistor you mentioned but might need to look more into that. I just used the standard stack up and settings with JLCPCB meaning I didn’t change any of their preset settings when placing the order.

WHAT?????? 420C to desolder the components!?!?!

Only the GPU, all others can use less heat but the lead free factory solder needs a lot of heat before finally starting to give. Those temps you mentioned would work with low melt solder after reballing, but wouldn’t budge with my testing of the factory solder.

Any updates it's very impressive what have already have done and I really don't like seeing Wii motherboard being cut to make smaller consoles and I think custom PCB would be 1000 times better
So your work is very appreciated

What's the issue with the motherboard being cut? With a custom PCB, the chips still have to be harvested from somewhere.

The cut motherboard is quite large for what it has to accomplish
And custom PCB would probably shrink the overall device even more also components just flopping around don't seem the most reliable

Not really? Omega trim is small enough to fit in the palm of your hand, and PMS3 (soon™), as well as some other boards, fix the issue of a bunch of wires flopping around. I don't really think that's an issue anyway. Most people have all their components and wires secured inside their portables.

I'm going to be honest I just like the less destructive option and for me perfect Wii would be something a bit smaller but retaining all the Wii functionality besides disk drive with HDMI
Even if those parts are closed of it just doesn't look the same to me more like a prototype that actually product
In some smaller Wiis heat mengment is a problem
If I had more free time I would make Wii in raspberry pi form factor compatible with coolers with HDMI and GameCube port build in working bt and dsi connect would be for the rest of controllers and memory slot
There is even a possibility of using pico for USB to gamepad
And integrated Ethernet adapter
And to make it nice to look at
Looking at PCB is my favorite part of disassembling random devices laying around
