Help with md5(md5($username.$pass).$salt)

Heya everyone.

I have a hash that is in the following format: md5(md5($username.$pass).$salt)

The username is the same for every single hash and it has no salt.

I've tried multiple methods with hashcat but I keep failing. I've tried with passwordsPro and it retrieved the password correctly (but I really hate passwordspro D.

Any suggestion?

Thanks.
