Homebrew Disable filtering when playing upscaled DS games?

[Mister_Keevs]

I know I'm not the first to ask about this (as there was a recent thread asking the same question, but I can't find the damn thing), but someone in it mentioned that modifying AGB_FIRM would allow for DS games to run upscaled without the blurry filter.

Apologies if my post is vague, I just want to know if it's possible. If anyone could link/find that thread, that'd be great as well.

 

[RocketRobz]

Definitely possible.

They're not upscaled, there is no filter. They're blurry because they haven't been upscaled.

Huh, that's interesting.

Neat. Has anyone been able to pull it off?

Doesn't holding start or select as you boot up a DS cart run the game at its original resolution?

It does, but that makes the image smaller. I'm wondering if there's a way to upscale the games to fit the entire 3DS screen without the blurry effect you'd normally get.

i dunno, but while searching google for nds rom injection for loadiine tutorial, there was one that mentioned changing the configution.json file inside the contents folder. Apperently at the end of the file (open in text editor) there is a section call render method. It is set to one, you can change it to something higher like 2 for better quality.


There was snapshots comfirming to work. If that helps at all.

That's on the Wii U though :/

Yes, because the wii u emulates ds games, the 3ds has native support for them. Anyway, it would be cool to have custom bars, and not the black bars on the sides that we have now.

Yeah, i did say loadiine, though, i dunno how 3ds would work, the games on 3ds are in a file called cia that is installed to the sd card with the system. i dunno if there is a way to extract data like on the wii u games with loadiine everything is extracted data for easy file exlporing, cia are complied together (equal to a zip compressed file) is there a way to extract cia data and explore the contents for a configuration file like wii u loadiine titles?

It's completely different on 3ds, as it has native support. There is not a Cia for ds games. Yes, there's Wario ware as Cia, but it was converted to dsiware. And so there isn't a configuration file.

I dunon if this will help somehow... but maybe it will. if there was eshop nds games for 3ds it may be something to hope for. since regular ds cart games just do what it supposed to. backward compatible

All the ds games released as Cia, are actually dsiwares. So it works along with twl firm. The only configuration that we can change are in twl firm.

There is TWLfirm, but I highly doubt it would have a configuration file.

The slight blur is by design. The 3DS's resolution is about 1.5 times the DS's resolution, so normal scaling would look bad.

Oh, i understand now. I'm so oblivious today, apologies. So just like it was stated, since ds games run natively in ds mode, not by emulation but by backword compatibiliy, it could just be something in the system itself.... nand, to maybe modify but is a fools errand. Doing any mods to internal system is always risky, so unless virtual console comes to 3ds eshop, is just a waiting game or a bad dream.

They have to be upscaled to fit the entire screen, they just have no filter

EDIT: now i'm wondering if twl_firm can be modified to have an upscale filter... or better yet, actually upscale the resolution like desmume x432r

Doubt the latter is possible, but the first bit is what I'm trying to figure out

 

[DSoryu]

So I was going to ask this same question, reason of this bump.
Considering there have been new achievements regarding DS hacking and DSi hacking, and ndsbootstrap lately, is this possible in some way?

I mean, to add an upscale filter to TWL_FIRM or something similar.

 

[KoalaBoy]

that would be amazing. most of my favorite DS games look extra ugly on the 3ds (a lot of them rely on pixel-perfect rendering), so some sort of filtering would definitely be welcome
