When it comes the new patch for widescreen ds games? I tested the previous one that you did it and I'm excited to get the two working and the same time. More screen + sharper visuals.

I'm sorry to tell, but the widescreen patches tar out the horizontal scaling matrix, so what scaling method you choose will only be applied to vertical stretching.

Also, it'll probably look worse because of this, because there will be double pixels and single pixels, and it's very visible on the text, sadly.

Yeah I'm hoping GBA games can look better with a whole 50% more pixels to work with instead of 25%. I think mGBA does a pretty good job with scaling, so it would be nice to have some options closer to that in VC too.
Isn't GBA already scaled at 1.5x by default on the 3DS? (240 x 160) => (360 x 240). It looks pretty good to me .

Yes, it is, but my widescreen GBA patch scales it to 400x240 (5/3 width, 6/4 height), and due to space limitations I have to tar out the horizontal matrix to prevent visual artifacts and/or hardware lockups.

Are you using TWiLight Menu? This happens sometimes, in certain builds of nds-bootstrap and some games. It's somewhat random and goes away if you close the 3DS and open again.

It's a TWL_FIRM issue (unrelated to TWiLight Menu++ or nds-bootstrap), and can happen anywhere in DS/DSi mode, no matter the app or game.

Still it's SOMEWHAT random. It happens only in some build of nds-bootstrap and certain games. Results may vary even if you build the same commit with a different version of the toolchain however they're consistent. If you get it once you'll get it always.
I've never seen it happening in TWiLight Menu itself though, only in games.

I've had this happen some time ago using a flashcart, before nds-bootstrap was a thing. System did have Luma installed.

If none of you want widescreen scaling then I could try something else, but so far I haven't been so lucky with GBA's 1.5x scaling :/ No pattern looks good. The sharp pattern has duplicate pixels, which is looks horribly bad with text.

I'm really looking forward to widescreen for the DS games more than anything else. The GBA already fills most of the screen (more than the DS games do), and GBA games look pretty sharp already (sharper than the DS games at least). If there's room for improvement for the GBA VC games, I'm all for it, but widescreen and sharper picture for the DS seems more useful to me.

Thank you for all your work on this.

Regardless, once you get it once you get it all the time if you follow the same steps. I guess it's something about the way the roms are loaded.


Screen burn is an issue with backlight levels, not filters.
Nope, the backlight is provided by a led strip. An LCD screen can only filter light, not produce it.

How the hell is that even possible, I just managed to change the filters in GBA mode, how do you know such thing is possible?

Btw, 3DS screens don't really get screen burn. Or if they do, then I'm extremely lucky. I always leave my 3DSes on, waiting for me to upload new code, and the screen stays there sometimes for 4-14hrs, and I never had a screen burn in.

I'm assuming he's referring to 3DS getting their backlights blown out by setting them super high. (not really "burn-in".) It was supposedly a thing when CFW could set the backlight level to custom amounts.

The only backlight patch I know of is unstable, and crashes after a while for unknown reason. I don't think custom backlight amounts are possible yet other than that patch, and it's definitely not widespread for this to be an issue.

Also, it's really hard to just "blow out" the backlight on the 3DS... there has to be some other problem. Also, a blown backlight would make the 3DS turn off INSTANTLY the moment the backlight dies, so yeah...

I think that they probably meant that one issue that happens with certain GBA VC games when you remove ghosting via the color restoration process (which is completely optional). It certainly makes more sense than backlight issues.

Blur? Motion blur? Sounds like complete nonsense.

I think what happened is that the backlight's heat (no light source is perfect) slightly toasted the LCD layer, which caused it to slow down to the point where some pixels would get stuck.
I'm pretty sure that if it's a regular TN panel 3DS then you could fix it by lowering the brightness and letting the LCD layer cool down.

Edit: cheap IPS panels ghost more than expensive IPS panels. Just a wolf cry. IPS panel 3DSes are rare as hell, so it should barely affect anyone. Nothing to worry about, just don't let the panel heat up too much.
