Homebrew TWPatcher - DS(i) mode screen filters and patches

[KokoseiJ]

Can't update past 11.6 for multiple reasons, and 3DNUS doesn't work anymore afaik

Doesn't getting a system file still work? try 11.13.0-45U in there If that's what you need.

So I'm having an issue getting Widescreen to work on my CFW O2DS (using Mario Kart DS as my test game).

I followed the guide for 3DS/2DS users on the Twilight Menu++ thread (on the 3DS/2DS: Playing Widescreen tab), using the TWPatch recommended on the guide there (first post of this thread) and also the new, anti-wear patch version posted recently.

But I couldn't get either one to work by making games widescreen (also tried Phantasy Star 0 and Dragon Quest Monsters - Joker).

I verified that usrcheat.dat was actually in the proper folder (sd/_nds/twilightmenu/extras) and even tried enabling the cheats there manually...but the games ignored both the general 16:10 setting AND the game-specific one, appearing only as 4:3 ratio. Any hints on what the issue could be?

Are you using Luma? Did you enable "External module loading" in the SELECT boot menu?

 

[Statesman]

Are you using Luma? Did you enable "External module loading" in the SELECT boot menu?

Yeah, I'm using Luma and I did enable the "Enable external FIRMs and modules" option.

 

[Sono]

Weird... do you have TwlBg.cxi in /luma/sysmodules/TwlBg.cxi ?
Also, did you hold X before pressing START when patching? If your version supports widescreen then it should say it in text to hold X for widescreen.

Huh. Odd.
If you DM me over Discord and tell me how to get the TWL_FIRM, I can help.

 

[Statesman]

Nope, should I leave a copy there?

I did (and it does say so).

Do you have Widescreen.cxi in /_nds/TWiLightMenu/TwlBg/?

 

[Statesman]

Do you have Widescreen.cxi in /_nds/TWiLightMenu/TwlBg/?

I do.

 

[PrincessLillie]

I do.

Is widescreen enabled in your TWiLight Menu++ settings?

 

[Statesman]

I'm starting to think that maybe I should i

Is widescreen enabled in your TWiLight Menu++ settings?

If by enabled you mean having the "Screen Aspect Ratio" set to "16:10" in TWLMenu++ - Games/Apps settings, then I do.

Starting to think maybe Step 9 is messing up Step 4 (from the Twilight Menu++ Widescreen instructions).

Spoiler

1. Get TWPatch here.
2. Install the CIA.
3. Launch TWPatch.
4. Press X+START to generate a "TwlBg.cxi" file with widescreen.
5. When it's done, move "TwlBg.cxi" from "sd:/luma/sysmodules/" to "sd:/_nds/TWiLightMenu/TwlBg/".
6. Rename "TwlBg.cxi" to "Widescreen.cxi".
7. In Luma config, enable external FIRMs and modules.
8. Re-launch TWPatch.
9. Select a filter of your choice, and press START.
10. In TWLMenu++ settings, switch the page to "Games/Apps settings", and set "Screen Aspect Ratio" to "16:10".
    This can be done per-game as well.

Yeah...
When you make the second TwlBg.cxi in step 9, leave that as /luma/sysmodules/TwlBg.cxi.

 

[Statesman]

Huh, updated Luma from the previous latest version to the actual latest and the isue fixed itself *shrug*

Thanks everyone for the assistance.

I have some interesting news... it's both good and bad.

The good news is that the new anti-wear patch is not needed. It turns out I misread the disassembly, and upon re-inspection when doing a writeup on how the patch works, I noticed my mistake, and after further testing it turns out that the flash is indeed only written when you only change some settings.

The bad news is that this somehow doesn't work for everyone, because peoples' WiFi flashes are still dying somehow, so this patch is still needed.

So the patch is needed... but it's also not needed?
I'm confused. Are we sure the settings write is what's killing the WiFi flash?

 

[Rahkeesh]

I guess its more like an extra safety valve, since we don't know the cause of wifi flash failure yet, and some unknown system configurations causing excessive flashing remains a possibility.

Yeah.

At this point I don't know either. Because I'm working with a pre-1.0.0 TwlBg, I can tell that these checks have been there before it was released to the public, so it doesn't make sense why some 3DSes are still bricking themselves...

I guess its more like an extra safety valve, since we don't know the cause of wifi flash failure yet, and some unknown system configurations causing excessive flashing remains a possibility.

Basically this.

I made a patch which would fill the top screen white when a write happened (but actually just crashes the 3DS with a loud pop 4x to 8x louder than usual), and it would only trigger when I changed something, just as we expect it to work in the first place.

Another thing I noticed is that it doesn't rewrite the WiFi flash if the WiFi flash is corrupted beyond usability, it'll just fail if both backups are corrupted. The problem is that on some 3DSes we're seeing the opposite behavior for some reason even though these checks have been there before any retail system was released to the public.

@Sono Hi I have a question regarding one and that is changing the screen filter. I don't seem to find any instructions expect some post about use the button Y+B which dosent seem to work. It would be awesome if you could explain or guide me a little bit.

Filter can mean a lot of things. What do you want to do? Filter out blue light?
