Hacking vWii in 480p automatically?

[Deleted member 42501]

Why would you use 720p on Wii U?

 

[wheeeyou]

Just tried setting my Wii U to 480p and comparing it to 1080p on my LG 4K TV.

Surprisingly can't really see any difference between 480p and 1080p upscaling with Wii games. I would have thought 480p would look terrible. How ever the benefits of 480p for me are that the Wii games completely fill the screen. In 1080p some games would produce small black borders or fill like 90% of the screen.

Could the newly leaked Wii stuff be of any help in our quest for automatic 480p goodness?

So, the closest I've come to obtaining this is setting 480p in settings and adding a bit of code to change to 1080p into CBHC. And alas, launching the vWii system menu from the CBHC menu loads it in 480p. Unfortunately the stock vWii shortcut inside the Wii U menu still stays in 1080p for some odd reason but this can easily be mitigated with a custom homebrew forwarder that sets 480p then loads the vWii. Unfortunately I have no idea how to create homebrew in installable format besides installing haxchi over a random DS game backup (which doesn't make a difference since CBHC already has sigpatches.)

That sounds interesting as I'd thought that maybe if we circumvent the Wii U mode entirely and go in via the CBHC preload menu using a tweak that should give us 480p vWii whilst allowing a standard boot to stick to 1080p.

Could you share some more details of your approach as we've got a few great coders on here who could help take it to the next level as this addition would make the Wii U even awesomer than it already is.

All I simply did was add in this, but I wouldn't fully recommend doing it because if you compile a bad build you won't really know until you've bricked yourself. The "next level" I'd like to take it to would be adding the same code with a different resolution mode into https://github.com/FIX94/rpx2hbc and changing the target title to the system menu

CMPTLaunchTitle(databuf, datasize, 0x00000001, 0x00000002);

so we could have a "Wii mode" channel that sets 480p beforehand. I've made a fork (haven't pushed yet) dubbed rpx2vwii but I've been having a hell of a time getting a working channel due to the very specific setup that is required, and unfortunately the link in the README for the wut stuff is dead.

Following this thread! Just modded my GameCube and would love to replay my Wii games, but would rather buy a Wii U and play games in true 480p. Any comparisons between a 480p Wii U over HDMI and a modded Wii with WiiDual over HDMI? If we can crack how to automate 480p over HDMI for Wii games on the Wii U, we may have found a new, easier, and potentially cheaper way for people to play their Wii games with a higher-quality picture. Thanks for all the hard work guys!

I took a somewaht similar approach here in the hbl2hbc thread:
https://gbatemp.net/threads/hbl2hbc...hbl-into-vwii-hbc.455673/page-12#post-9079711

difference:
switches to 480p when you boot in vWii mode
install usb loader forwarder channel in vwii and use this as target to skip vwii menu/homebrew channel
in the above thread is already a channel for WiiU if someone dont want to start via homebrew launcher

but be warned:
vwii via wiiu isnt that great (picture quality), no matter if you use 480p, 720 or 1080p as resolution

The main problem is that vWii output isn't 1:1 even at 480p. 16 pixels of "overscan" are cut out and what remains gets scaled up to 480p, creating blur from interpolation. There are also some color sampling issues as well.

Dang, really hoping we can see some firmware mods for the system. Seems like we're in the Gamecube swing of things lately, but in future years as people move up and begin modifying later systems it's probably going to become a big project. Would love to see a new HomeBrew app that we can use to boot the custom firmware and get games playing properly. I'd much rather have one system the play 3 generations of games (GameCube, Wii, and Wii U, though I personally like the GameCube for nostalgia's sake). Here's to keeping that hope alive!

Sorry to bump an old thread, is there an Aroma solution to this? Thanks.
