Worklog Indigo G-Wii rev 2 Revived

[Alvaro]

Basically 6 years ago I built a G-Wii with sub par skills and tools. It stopped working pretty fast and I never got around to fixing it. Years later my soldering skills and tools have gotten much better. I finished the G-Wii in about 3 days from scratch (Including desoldering, disassembly and cleaning some very stubborn flux residues from fake ebay flux that aged badly).

Some mishaps happened while fixing the board up which i had to figure out. My HS/VS pins had no more pads and I accidentally broke VS pin off while probing to troubleshoot VGA. I basically just winged it and grinded back the AVE chip a bit and soldered a wire there lol. Then it turned out the VGA was not working because the VGA patches weren’t applied so I went to wire up the GC+ just to navigate RVLoader in composite and run the installer and then it thankfully worked great! Also had to resolder the wire to the 3.3v on the nand. In the end here are the pics just so I can document some stuff I suppose. (Last pic is from when i finished it 6 years ago to compare)

Also on a side note, I hooked up the U-Amp to SCW and SDW but also wanted the physical buttons to work with the HUD. I can’t find any info despite hours of searching and the one video mentioning it by Aurelio was made private. So does anyone know which GPIO pins I should hook my + and - volume buttons to?

The only one I found info of was the HS pin which I also have wired to the U Amp.

Anyways thanks for all the hard work and information thats out there already!

Alright well I was browsing around 4layer and stumbled across the RVL-AMP. In those diagrams I found the GPIO via for digital volume controls. I could not find this anywhere else! And I have a U-AMP so I was always just looking at those pinouts instead. A little crazy no amount of googling or searching could find that info because its on a picture diagram lol… Anyways, I want to enable digital volume controls with my U-AMP. I was told I can hook up to the GPIO pins and bridge all jumper pads but that’s it. Upon reading the diagram it says to hook up the button to the RVL AMP first then AMP to GPIO via because it requires a 3.3v pull up resistor for it to work.

So what did I do? I attempted to implement my own pull up resistors because I don’t think the U AMP has any. I did this and it’s not working. I’m a bit of a noob at the technical knowledge but I believe I implemented this right and it’s just not functioning. Some help would be greatly appreciated because this has been driving me crazy lol.

I wired 2 10k resistors to 3v3 directly then from there two wires on the end of each. From those wires one goes to the button and the other goes to the GPIO via. After researching and looking at diagrams, this should technically work right? The junction is at the end of the resistor where it should be pulling GPIO pin high when the button is not pressed and then when the button wire shorts to ground it’ll pull this low and suppose to send command. Input would be greatly appreciated thank you!
