[sinisterMayo]

heya, im a complete noob so this will probably make everyone here cringe really hard, but how do i my unpatched twlbg.cxi in the first place. sorry if this has been said or if im stupid.

follow this guide and look at the wide screen tab for 2/3ds (https://gbatemp.net/threads/ds-i-3d...-ds-i-games-and-ds-i-menu-replacement.472200/)

Widescreen instructions are in the first post of the TWLMenu++ thread. You don't really need the unpatched TwlBg.cxi

Quick question. What would I need to do in order for DS games to display as #3 rather than #1 or #2 in the attached image?

I'm guessing I'd have to hex edit something in TWL_FIRM for the 1x mode to display centered in each screen rather than on the bottom (top screen) and the top (bottom screen) but I have no idea what offset that would be or what I would need to change it to. Any help would be appreciated.

I don't know but #3 is really ugly. You'd also have to adjust the touchscreen handling a little, to compensate for the different positioning.

Where is this "guide" everyone keeps mentioning? I came here from the front page news post and the post with the download is a little lacking in details.

Thanks for your opinion. And yeah, I figured I'd need to edit the touchscreen handling as well, but if that's too difficult I wouldn't mind forgoing it and just sticking to playing games that don't require touch controls.

I have to patch the OpenGL driver, AND the matrix unit driver, otherwise the 384x240 will be scaled back to 320x240 by the PICA GPU (which btw looks REALLY nice because it's not blurry, other than Mario being a bit squished thin)

Sono, sorry for the hassle and for what I'm sure constitutes a misunderstanding of how all of this works, but I've been thinking about this ever since you posted it. The subject just came up again over on Discord so I figured I'd ask: If you're able to patch the OpenGL driver, what's to stop you from scaling to a full screen 400*240 using the PICA200 instead of/in concert with the scaling matrix? The matrix obviously limits you to that whole fractional setup, but couldn't the PICA just scale arbitrarily to any resolution you wanted, like, say, full 400*240, 5:3 aspect ratio?

1) because GPU scaling requires more memory bandwidth
2) because I'm an idiot, and can reverse engineer a hardware without any symbols and documentation and make patches for a fully undocumented and extremely complex OpenGL driver, but can't think of something as simple as to stretch the image using the DMPGL patch... I actually did it once by accident, AND THE PICA's LINEAR SCALING IS SUPER PLEASING ON THE EYES! But me being paranoid I completely forgot that this is even possible. I could just disable the X scaling all together, and use the PICA's amazing quality linear upscaling to stretch the X axis...

Welp... I tried every combination of values, and I just can't get GPU scaling to work :/ The image is always left-aligned, but not stretched. I have probably changed the patch used, because I just can't reproduce it anymore

@Sono Thanks a lot for all your work. Any word on screen swapping for the ds mode? Don't mean to rush you especially because of all you've done (even more so in that hungarian weather)

If you go back a "few" pages then there should be some images showcasing a buggy version of screen swap.

I'll link the images I found, but there could be one oe two more which are probably not worth to dig thru' the pages for.

Spoiler: Image

I think something is wrong with the TWiLightMenu 0.9

If I put the atched cxi here :
D:\_nds\TWiLightMenu\TwlBg\Widescreen.cxi
It didn't work.

If I put it here
D:\luma\sysmodules\TwlBg.cxi
Work in stretched mod.

I don't understand, why it didn't work as it should

I use Luma + 11.8.0-41E on an old 3DS

@chocoboss TWiLight Menu++ is not supposed to be stretched at all, it reboots into Widescreen.cxi when you launch a game that TWLMenu++ has widescreen support for. The menu itself should look normal.

 

[chocoboss]

I know, but it didn't boot games in widescreen mode if I put the patched cxi
D:\_nds\TWiLightMenu\TwlBg\Widescreen.cxi

It just boot game in normal mode q.q

You must update TwilightMenu++ to the latest version manually, since the updater can't for some reason, causing this issue.

 

[chocoboss]

I have install it manually a few days ago, I was using a linker before ! =)

 

[Vague Rant]

@chocoboss Maybe obvious, but did you turn widescreen on in the TWLMenu++ settings?

 

[chocoboss]

I have installed it using this :
https://gbatemp.net/threads/ds-i-3d...-ds-i-games-and-ds-i-menu-replacement.472200/

and 16/10 is enabled.

I have try with pokemon games + mario kart

Is there any difference putting it in one folder or the other ?

 

[Vague Rant]

@chocoboss Putting it into sdmc:/luma/sysmodules will only cause stretching, not actual widescreen where you can see more of the environment.
