Hacking Coding vWii 3-core support - everything you need to know.

[Maxternal]

Thanks for testing. That was untested when I posted it. Unfortunately, looks like I didn't QUITE do it right. I'll have to make some adjustments and recompile when I get a chance here.

For anyone who was curious about this, here's that part of the log of the WORKING version of this

so the value of r3 that's written into SCR is 0x80000000 that disables the bootROM.

f0f were right: http://www.eurogamer.net/articles/digitalfoundry-2014-secret-developers-wii-u-the-inside-story
(Interesting reading)

 

[Henke]

THQ troll is probably the anon poster. Read this to counter that article : http://nintendoenthusiast.com/news/harder-develop-games-wii-u-case-says-renegade-kid/

 

[asper]

Read both, dunno were is the truth as I am not a developer...

 

[rednekcowboy]

TBH, the super secret dev in the first article sounds like he doesn't know his ass from a hole in the ground and wanted Nintendo to develop half of the game for them.

 

[obcd]

First of all, this has nothing to do with 3-core support, so it should be a new topic.

Even if developping for the wiiu wouldn't be more difficult than developping for other consoles, if you concentrate on xbox one or ps 4, you can have a game that runs on 2 of the 3 nextgen consoles. If you concentrate on Wiiu, you'll end up with a game for just 1 of the 3. Further, if people aren't having the console, they won't buy that console game. The number of devkits showing up on ebay also indicate that some developpers tried and later on abandonned the wiiu.
It's a bit a chicken egg situation. If plenty of consoles are sold, plenty of good third party games will be made for it which will again lead to good console sales...
They just need a very good exclusive to start this circle running.

The dev in the first article is just highlighting the fact that Nintendo support was poor and slow.
If you have a Team working on something, discovering an issue that freezes their progress, you have any idea how much it costs if you only have your question answered after a week? So they don't seem to have english speaking engineers at Nintendo HQ?

It's not what I want to see happening, but if you order the facts, the future isn't bright.

Bumpty! I realized the donation button on the googlecode page is gone. Does this mean there's enough money for Maxternal to get a Wii U?

P.S. The donation button is still clickable. (There's a blue period on the page).

 

[Maxternal]

Bumpty! I realized the donation button on the googlecode page is gone. Does this mean there's enough money for Maxternal to get a Wii U?

Yes, it does. It'll just require waiting a series of bank transfers before it's actually in my hand but the answer is yes so a big thanks to all those who helped in this.

P.S. The donation button is still clickable. (There's a blue period on the page).

Fixed.

What purpose did I serve this whole entire time 'cause I see you've got credits some like marcan, sven, comex, cory and many more.

That portion of that post was directed more at those who donated but, of course, there were those who even just spread the word about the project just or helped out with enthusiasm and moral support, too, so even if you didn't/couldn't help with technical knowledge, there's always other ways.

So I did help out! Yes! By the way you might wanna update your starting post. Also the "donations" word on the googlecode page is still blue also.

 

[Maxternal]

anyway, here's another version of the boot.dol meant to just send the cores straight to Linux and let the wrapper take care of any initialization.

i see pom-poms every time you post in here, if that helps at all.

 

[Pogostick]

What's that supposed to mean. Pom Pom from SM3DW or pom poms that you hold in your hands. Sorry if I'm getting offbeat.

 

[crono141]

Pom-poms, the thing cheerleaders hold.

 

[Pogostick]

i see pom-poms every time you post in here, if that helps at all.

Are you saying I cheer every time I post?
