If you find a ROM that's encrypted, you need to use the Batch CIA 3DS Decryptor, created by Matif.
Not all games are fully compatible with Citra. If you do find a game that's not working, try using the latest PabloMK7 Citra fork, the continuation of Citra since its shutdown.
Citra is an open-source 3DS emulator for Windows, Mac, Linux and Android devices.
It is designed to recreate the functionality of the Nintendo 3DS system on other platforms, enabling users to play 3DS games in higher resolutions and with improved graphics.
