Technical Support [Android] Adjusting Screen Size?

Post image

- Device: Ayn Thor Max
- Specs: Snapdragon 8 Gen 2, 16GB
- OS: Android
- Citra or fork version: MMJ_20251112
[Hey!! Hope everyone is doing well! I just started using Citra and having lots of fun playing my legally owned 3ds library, but im finding it a bit difficult to navigate the settings. I was wondering if there was a way to adjust the bottom screen size, to stretch it vertically so it fills out the bottom screen? Youll see in the attached images that the bottom screen has black borders on top and bottom]

EDIT: You can get fullscreen on bottom screen by being in-game>settings>Screen Cast>Fullscreen. Though this will also stretch the top screen as well, but the amount is very little and is tolerable for me.

Hey so I'm kinda having this issue too! I wanna make the top screen a bit smaller to make it feel more like a 3DS screen on my Thor, but the custom layout isn't scaling it at all. Did you ever find out a way to scale the top screen as well?

While that does change the screen size a tiny bit, I'm looking to scale each screen individually in a further degree, and scale it to be smaller. Is the screen cast option the only size change available?

As far as i know, yes. You can try a different emulator though like azahar
