Just a question about helping with the compatibility list

I was trying to help with the compatibility list but, the page give an error about “invalid size” with the screenshots, it says the screenshots have to be at native resolution, and I read and saw in the emulator that it is 400x240 px, my screenshots have that resolution but I got the error so… what am I doing wrong?

400x240 is for the top screen only. Screenshots should include the bottom screen as well which should make it 400x480. We recommend users use ShareX for taking screenshots.

For any compatibility database inquiries, please refer to the contribution guidelines. If you need any assistance with clarification, feel free to ask.
