can't figure this out, new to hashcat

[mercurial]

so I tried this, after looking through loads of guides.
I suspect my hash is in base64, and it is salted? (How do I know if I'm right?)
So that's why I used -m101
Can't really figure out what's wrong with it.
If it's to do with the fact it's salted, can someone help me figure out how to unsalt it (hahahaha… Is that even possible)



(By the way it's not a real password it's just a fun challenge so I'm fine with sharing the hash if someone asks haha)

Hold on!!!!!!!

I was wrong, and looking through the example hashes I see it's actually encoded like the m1413 one.
" base64(sha256(unicode($pass))) "

Is the right way to tackle this download a legacy version of hashcat ?
