Heya! Trying to got Pokemon Black working with the widescreen fix in Twilight and got it working! Now, the issue is the scaling completely destroying the sprites. I've tried a few different scales from the patcher, including the gpu scaling option, but none of them seem to fix the cold dead pupiless eyes of my Pokemon trainer. Haha! Any suggestions for a fix?

It is not possible to fix without changing the rendering resolution of the screen, which itself is impossible, as the DS screens are designed to use that resolution (256x192).

The way that this works, does it apply a widescreen effect to all DS games that only stretches them out, and then once you've applied these cheats, those games with the cheats will then display in proper widescreen and not stretched out?

Like is it global that all DS games now have the stretched widescreen patch applied to them, or does it only apply to the specific games you desire. I want to apply these to a few specific DS games on my 3DS, but many of them that I have do not have such widescreen cheats, so I'd rather play those titles in their native non-stretched display. Is that achievable, or would I have to manually change a setting anytime I go from playing a non widescreen DS game to a widescreen DS game and vice versa?
Sure, you need to activate before the Widescreen patch (.xci) from TWlPatch with all the other things, plus you need to toggle once a game the 16:9 option in the TWiLight Menu

Hello!
I made a 16:10 code for a homebrew game, DScraft, and it works great in desmume, but DScraft doesn't even have a cheat option in Twilight menu, and if I boot the game with a forwarder whilst holding Y and enable the cheat that way, it says it's enabled but nothing happens in the game at all! Does anybody know what I'm doing wrong?

16:10 widescreen!

It is currently not possible to use cheats with homebrew.
For now, you'll need to apply the patch to the ROM itself.

is that even possible? i've looked into patching cheat codes into roms before and all I could find was game genie guy, which worked great for what I wanted it for at the time but doesn't support DS, and DSATM, which is designed for DS but features no text input for cheat codes, crashes if i try to load a database file, has a clipboard button that does nothing, and literally randomly entirely deleted itself from my computer....

The patch needs to be applied via a hex editor. Open a ROM using one (HxD, for example), go to offset 9D74 (use the editor's Goto feature), and type 9A 19 over 55 15.

I'm not exactly sure how it works, but I wish it was an integrated option in twilightmenu without having to craft/download/use cheats

Apologies, I actually confused the cheats with the twpatch option. I'll try it later to see if it works. Thank you for the clarification.

Also, I wanted to ask if there is a way to apply the aspect ratio change from the shortcuts in the home menu because I usually use 'ndsforwarder'

After launching the forwarder, hold Y until a menu appears. You'll see the option to change the aspect ratio.

For New Super Mario Bros., I don't see the code listed here. I have the code from my usrcheats.dat which I got from a github page. This is the code I have:

Why wasn't this code listed here though? Instead there's a video to the patch made by gamemasterplc.

I'm playing with it now. I'll have to compare the code to the patch and let you know which one is better. From what I can tell so far, the code is stretching the Goombas. The Fire Flowers when they are on top of an opened brown power block, they are kind of off center. There's other minor issues. I'm guessing the patch does a better job, but the problem is, I can't combine the Widescreen patch with any other patch for the game.

I have to say it doesn't work tbh. Everything is off center, and it just doesn't look good.
