16:9 widescreen cheats/mods

Hey, I was wondering if there are any cheat codes for aspect ratios as there are some for DS games, I thought it would probably be possible with 3DS games as well but I haven't been able to find anything.

Also no, I don't mean stretching, texture packs, layouts, upscaling or whatever, I mean the same way you can play N64 games with 16:9. I'm extra saying that because I've seen another post with the same question that only got answers that weren't related.

I don't know why I have to include this but here:

• Device: Desktop
• Specs: 7950x3D 96GB RTX 4090
• OS: Windows 11
• Citra or fork version: azahar 03d62ef + DualSense touch input + SMAA
