check how those are configured. I'm not sure myself. I think there's an nes tutorial iirc.
Afak, I've only seen tutorials for the Wii VC, not for Wii U yet.
Last time I saw someone asking about it, there wasn't a definitive answer.

I pressume it's 'cause people had not employ the needed time for that task. If it's something like the Wii VC, I understand the lack of investigation (compared to other parts of the Wii U VC), as it's kinda hard since you have to mess with hex values and stuff like that (thanks @SaulFabre for giving links to condensed info about the topic) in the way that you have to checking specific values and following a guide precisely.

Tbh I don't know how it would work on Wii U VC, I'm just speculating here, but if it's something like the Wii VC I will wait for an automated tool or some injector, since modifying hex data game by game would be pretty trivial and even hard for some people.

I did this tutorial on my only other purchased gba game, but with that one I noticed no difference. It was super mario advance 3. It had .75 as brightness, but the before looked normal (very bright).

This is nice, I wasn't sure why this was done. Most of the time, I just hear people say "It helps prevent epileptic seizures." I personally never had a history of it, but I understand the safety. Though this is a poor way to do it. Like the more modern emulated versions of the games nintendo has done, they modify the games directly to reduce flashing bright lights which I think is a lot better. (Even though it does kinda reduce the immersion of the effects)

Still, I'm glad there is ways to remove it now. One thing I would hope to see is a way to change the smoothing filter that it has. (Clicking the right stick enables the smoothing filter) I'm not expecting it to be done, a better smoothing filter like xbrz would be nice

Never heard of that smoothing filter.
Gonna try it later.

I don't recall that specific option in the config file. the config file is rather small and has things like game name, brightness, game rom name, etc. it has a few options under brightness, but I forgot what they were (not sure what they do anyway). I'm going to post the before and after with super mario advance 3: yoshi's island. I noticed no difference turning the brightness up to 1, but the game looked normal with it at .75. I think there's a difference with the golden sun one I did above, but I chose a bad picture to use for the before and after.

I just had a look at this myself. While it doesn't really show up in your photos, the brightness is changing (fairly dramatically) on my end.

Modern digital cameras (that includes phones) have all kinds of automatic white balance tricks which throw off photos. Judging the brightness can be tough because a camera might automatically brighten up a darker photo, or darken a brighter one.

it was bright on my end from the beginning, not sure why. I decompiled the m file again after I noticed that to make sure brightness was set to 1, and it was. doesn't really matter much though as the game looked normal either way. really weird.

@Vague Rant

Then all GBA Wii U VC games have reduced brightness to 75% (0.75 value)?

Good thing that you noticed that the 1 value is 100% brightness to GBA Wii U VC, so it's a great achievement on the Wii U scene.

Also good thing that Wii U VC saw Yoshi's Island: Super Mario Advance 3. It's one of my favorite GBA games, also a good port of the SNES Super FX GSU-2 game Super Mario World 2: Yoshi's Island.

@godreborn

Have you saw and taken photos of the original VC release of SMA3: Yoshi's Island with the reduced brightness? For try to see your comparison between these two brightness values

that's what the above is supposed to be. I just took a photo of the game selection screen:

Maybe your phone camera IS tricking you with its auto-adjustment of the photo brightness.

Do you have an HDMI capturer for record a short video of each brightness on your Wii U and then make screenshots on your PC for see the real difference?

no, it looked normal on the tv screen without the brightness changed to 1. I just decompiled the m file again. it's set to 1, but it was ,75 when I originally changed it:

Then the TV is trolling you with its screen and colors brightness adjustment.

Have you tried changing the image settings mode to the "Normal" mode with default settings instead of "Vivid", "Sports" or another?

I was trying to compile the file with something like .50 or something, but I've encountered a weird problem, and it only happens in this json file. if I put a decimal whatsoever, the text turns white, and it will not compile at all.
