Homebrew Question Capture framebuffer

[Llerd]

Hi,

I'm wondering if it's possible to capture the current framebuffer at a very low level. I don't want to read my own framebuffer, but capture everything that is shown on the Switch's screen after composition. This probably requires low level communication with the Tegra. I'm looking at the lowest level libnx, but I could use some pointers if it's even feasable.

There is no libnx function that will give you direct access to framebuffer. The closes you can get is what bitmap-printer does, which gives you access to raw screenshot.
