Worklog Gman's Wii portable

[Gman]

Got mine on Amazon. 6 of them was ~$45

That's a great deal if they are decent quality and aren't actually like half the amperage.

They are Panasonic branded and everything with the rating listed on there.

Lucky you they went down in price. Official listing from Panasonic as well

Hey, don't need the MX chip!

 

[Gman]

YES Cheese! Can you explain what you did? Also what are we sacrificing by not rewiring it? Like can Wii games still boot?

 

[Air Conditioner]

Does this mean the that chip will be able to be cut off and make the Wii super tiny???

 

[Noah]

HOLY SHIT

 

[cheese]

Wii and Gamecube games still boot/run just fine. The only thing we would be sacraficing by not rewiring this would be the ability to turn the console on/off with wii remotes/power button, and probably the clock if the system loses power. Another weird side effect is remotes stay connected until the 3.3v standby is also cut.
Basically, pin 2 on the MX chip goes to the regulator circuits, and when it gets 3.3v, it turns on all the other voltages and causes the system to boot. We still need to pulse the reset line that U10 is connected to, but there is a via right underneath the GPU we can relocate that to.
So yes, we can lop off the board all the way back to the 1.8V LDO, assuming we can relocate wifi .-.

This is nuts! Amazing work.

 

[Gman]

Nice work, mad respect cheese. In all reality, a super Wii trim won't be much more difficult than an omgwtf gc, also a bit smaller too. Don't forget about the Ram on the bottom of the board, it extends a little past the 1.8v regulator, cant cut that off.

I'm still not sure how I feel about the trade offs of the Wii but I'm super excited.

Whoever gets the Wii smallest, post a picture over at GBAtemp or something to try and catch the eye of someone who may be able to help on the software end of things.

There really aren't any trade offs on the Wii. It's cheaper, uses less power, less heat, you dont need a modchip, and its not anymore difficult to trim than the GC. It's better in every way.

My thoughts
1. Video quality options (no true HDMI options like the GC video and the 480p is worse on Wii than GC)
2. More things to keep on check like wifi and Bluetooth (I suppose this is evened out by the WKF and SD gecko)
3. More revisions ( I need to educate myself on this) is it possible to know what revisions you get/want without dismantling?

Not trying to disagree for for no reason here but these were just personal thoughts of mine. I agree for general purpose the Wii is better but the GC has the video quality going for it. What does the power draw difference look like btw?

We are currently looking into eliminating all daughter boards. Wifi is only like 6 data wires to rewire. Any wii that isn't white or a family edition Wii will have a CPU-40 or higher which is easily trimmable. Unlike Gamecube, you can know exactly what motherboard you are getting before buying it. not sure on the power difference, but I will measure it at some point, It is definitely less.

Okay I was pretty misinformed/confused on that then. Wii is GOAT

This is more revolutionary (sorry Ashen) than the GameCube ttimming. Taking a console of this size, thought to be nearly untrimmable by most and turning it into this is the most exciting thing in portablizing since Ben Heck's guide book.

 

[Shank]

To be fair, the GC video will output better quality video through HDMI, without lag, to digital TVs. It is possible, but not likely, that GC video will be compatible with the wii.
But, for making tiny portables, HDMI is really too large to be used in most cases. And to get progressive out of a gamecube you need to buy and integrate a component cable chip or a gc video, while the wii has it built in.

This truly is revolutionary, cheese, and one of the biggest steps so far. I can't wait to see what else you can pull off.

Ooh baby, I'm hot just like an oven
I need some lovin'
And baby, I can't hold it much longer
It's getting stronger and stronger

And when I get that feeling
I want
, oh baby
Makes me feel so fine

Now this is cool stuff
