This one looks compatible, do you have more details for it? Like a pool you've been using? An announcement thread?
Thanks a lot for your help

I needed to set the variant to 1 to make it work with Cryptonight. Could I use Cryptonight-Lite to mine XTL and get better results? I was not able to make it work and I don't know why.
You're welcome

It doesn't work that way, it's a different algorithm. You need to use the algorithm supported by the coin.
I see Stellite has forked to increase ASIC resistance, you will need to get the
latest version of XMRig that supports CryptoNight V7 (the new CN algo for the forked coins). I assume the configuration is the same.
Let me know if you have issues with it.
