Wiikey Fusion eject switch; 1.9v needed

Okay, so.

Week or two ago, wiikey decided to spaz the *Can'tSayThisOnTV* out. Gamecube didn't even boot a couple times. After booting it up once while holding both the "eject" button and the "lid sense" button, it booted up and started working again.

Course now, I still had to push the button quite a few times to get it to load gclinux.

Then, a few days ago, the wiikey quit working all together. I tried everything, I knew my wiring was good, checked all the switches, all sorts of sd card formatting, etc.
Nothing was fixing it.

I decided even though it had worked plenty of times before with the "eject" switch on just ground and pin 29, hooking up 1.9v might be what the wiikey needs. One added wire, once pinch of potassium chlorate, one errant button press?

Ta-da. Wiikey works everytime I press the button, first try. Pretty Dang happy about that.

I suggest that, if you know your wiring is good, the blue light flashes in sequence with the "reading disc" message, you know your SD card is compatible and formatted right, and you can't get your WIikey to work?

Try this next.

I suppose it could have something to do with the Wiikey itself, or it's compatibility with this cube. I never had this problem with my last cube, it might have something to do with the board revision because the IPL on this one is the same as my last working one.

hmmm, interesting (said it before Ashen could :p )

Not sure if you ever tried this, but I figured out that you have to hold the eject button for half a second (as appose to a quick touch) to get it to boot sometimes. Also, have you tried taking out the 1.9v line and testing it now? Just to be conclusive about it, I guess.

Glad you got it working man.
 
Yeah, I've tried every different amount of time holding the button. Didn't change anything.

Problem comes right back without 1.9v.

This doesn't really surprise me much.

When I was doing all my testing way back when, before any of this Wii DD/Wiikey stuff was discovered I had tested what exactly the eject button on the Wii was doing (pin 29) when pressed and when not pressed. When being forced low it acts as some kind of disc recognition sensory thing. Without grounding this pin or forcing it low somehow or another the Wii itself will never recognize that a disc is inserted. When you press the eject button on the Wii it sends a 1.9v pulse through that pin which in turn tells the Wii to eject the disc. The Wii DD will not recognize the button press unless 1.9v is hooked up, the Wiikey and WODE chips seem to be less sensitive on this pin as to what will drive them "high" which is why the Wiikey and WODE (mostly) function without the 1.9v on the switch. There is always a bit of low voltage running through pin 29, and in most cases it seems its enough to drive that pin to a high state on the modchips.

EDIT: Just a little useless fact about all of this. This was actually the turning point for me when I was doing all the work with the Wii Drives on the GC. Once I understood what this pin was doing on the Wii is when I got everything working (Wii DD) on the GC.
