Only those who were available on the arcade version (before ver 1.30 who brought Es, Mai, Susano'o) were successfully ripped.
Not saying it's not a huge success though
The encryption of the console version seems different from the arcade version, which is why we still don't have Es, Mai, Susan. Either one gets to access the console version data through a lot of struggle and work, or people wait for the ver 1.30 ROM to come out and hope the process to rip them is the same. Or one goes crazy enough to redraw all sprites pixel by pixel from hi-res footages. If I were to give it a try someday, I think the arcade ROM would be the wiser option.
