Playing DS games on Wii U in 16:9?

[KelSolaar]

So I've found there are codes for DS games to run in 16:9. Is it possible to patch these games to run on the Wii U?

Have you seen there are new screen layouts that has been created?

Have a look to this great work:
https://gbatemp.net/threads/add-many-more-screen-layout-options-in-ds-virtual-console-games.574254/

Also this way is easy to install, maybe easier than tuning with codes that seems to be related to DS emulator and I am not sure it works on DS VC

Yeah I'm using that but it's not setting the actual games to 16:9. It's only stretching the screen area.
I'm talking about true 16:9 like the AR codes, but they seem to not work on Wii U.

It is possible. We have done it with the Analog Mario 64 DS patcher by hex editing the ROM. You might need to work out exactly what the cheat code is doing in order to make the edit manually.

Are there a list of hex codes?

There are lists of Action Replay codes: https://forums.desmume.org/viewtopic.php?pid=25853, https://gbatemp.net/threads/how-to-play-nds-games-in-hd-widescreen-16-9-21-9-32-9.538988/

But I'm suggesting you figure out what the code is actually editing in order to do it manually.

As Vague Rant points out in the thread I linked to before, many games store the aspect ratio of the view port somewhere then use that to render the correct amount of world. We are looking for the value for the DS's original 4:3 ratio:

55 15 00 00 //     old value: 0x1555 =  4:3

and changing it to:

72 1C 00 00 //     new value: 0x1C72 = 16:9

If you can't identify where this replacement needs to happen, you could just do a blanket find-and-replace, but this might break the game if it happens to use a value of hex-1555 elsewhere.

What games are you interested in? I may be able to help parse the AR codes.

Thanks!
Do you have the hex codes for Mario Kart DS and New Super Mario Bros?

which i would interpret as looking at address 020775D0 (and possibly 120775D0 and 1207898BC - use Find and see where the relevant value shows up?) and replacing value 1555 with 1C72 (it may show up as 55 15, in which case you replace it with 72 1C).

but I am not sure what this actually does.

You could also use DSATM https://www.gamebrew.org/wiki/DSATM to patch the codes into the .nds without doing the hex editing yourself.

New Soup needs to work differently as it's a 2D game and we can't squash the viewport in the same way. There is a video here: with a patcher here: https://www.dropbox.com/s/5mrrwp92i7qq38f/nsmbws.xdelta?dl=0 to make the game run in 16:10 for the 3DS. Then you can inject that .nds and muck about with the screen layout to get the aspect ratio correct. The DeSmuMe forum has a 16:9 code

you could inject with DSATM.

In any case I would recommend trying to run the patched games first on DeSmuMe on your computer before sending them to the Wii U, in case what you tried causes as crash - there's no point spending time injecting and installing a game that definitely doesn't work.

Hey mate I just wanted to say that I tried out that DSATM method and it works! Even when injecting the roms over to Wii U!
Thanks a bunch!
