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

[HailAndStormCats]

I've just used the GPU scaler patch on 4:3 (looks great in my opinion), but I'm noticing two issues:

1. Edges of some sprites have odd black pixels (not sure if this can be fixed)
2. The top line of pixels and the bottom line of pixels are switched

I'm on build 2020/07/18.

Also one (hopefully small) request: allow DMPGL scaling and wide patch to be used separate?

1) That's weird. I know there is a single release which has a fake GPU scale, but I don't know which one. You may have that build perhaps?
2) I never noticed that, but it could be Nintendo's driver bug. I can't do anything about that sadly.

Also one (hopefully small) request: allow DMPGL scaling and wide patch to be used separate?

It was possible in an earlier release, but I broke it while trying to implement mode800 patch.

Hiya! I'm wondering if it's possible to incorporate an option for centered 1x scaling in your software. has anyone else done it?

It is possible, and it's on the TODO checklist. I'm just not making any progress because I've been way too busy with work lately, and don't have time and energy to work on TWPatcher.

 

[famiac]

totally understandable. Thanks for your prompt reply. I know you don't owe me or the community anything, and I greatly appreciate the time you've already put into this project.

Also, install-related question, could you add a QR code for the CIA file in the main post? Last I checked, it wasn’t there and I don’t want to download the file before installing it.

There is not a QR code because I'm too lazy to spend 3minutes to update the QR code along with the link with the first post. Sorry!

The updates are so rare that you don't need QR codes.

If someone could keep me updated with new releases, I'd gladly waste my time making QR Codes

You could also upload it to a static URL like you did with the outdated stable and make just one QR Code

fyi Universal-DB has QR codes for this: https://db.universal-team.net/3ds/twpatch

(prereleases are orange) (the "experimental" one is the "prerelease", I used GitHub's term as most apps on U-DB are on GitHub)

So if you link to those they should be kept up to date, though since your experimental version isn't on GitHub I have to manually update the link U-DB uses, I usually pay attention to this thread though so it should be good

I noticed enabling GPU scaling doesn't work really well with Pixel-Perfect Resolution. If I press Start before loading a DS game, the screen will be smaller with DS resolution, but the image will be stretched. Kinda like a square forced to be a rectangle. Will this be fixed or is it an inherently limit of GPU scaling?

Yeah, there is no way I can fix that. Sadly the GPU scale feature is not inplemented enough to be patchable without side-effects :/

This is an impressive app.

The quality of life features, ease, configuration and implementation are all well done.

I'd originally skipped it as I never play DS games but checked it out and have to say its nicely done.

I recently tested the 2020/09/03 release and the GPU scale patch isn't working for my N3DS (= no wide screen).
The patch from the stable release is working!

Known issue. I broke widescreen + GPU. They work, but not together.

Oh, okay. What's the GPU patch doing again?

It adds both horizontal and vertical filtering. Without GPU scaling, only vertical filtering is used for widescreen.

Question relating to scaling: on non-N2DS models, couldn’t you use the double horizontal resolution to make the image (on the horizontal axis on the top screen only) sharper? (For those who will scream about the O2DS, it has the same 800x240 resolution on the top screen of the 3DS, but the N2DS drops every other vertical pixel)

O2DS doesn't have 800px mode, but the N2DS does.

O2DS doesn't have 800px mode, but the N2DS does.

N2DS has 800px in software but doesn’t have 800px on the LCD, and O2DS has 800px on the LCD but doesn’t have 800px in software... my brain has now died.
Edit: I’m dumb, got the New and the Old mixed up (my brain must actually be dead)
