New style sprite sheets

So, I am new to the boards. I have been tinkering with sprites for something like 10 years... I always did my work in FF3usSpriteED... but I see everyone here uses FF3se... my version was dusty and unused so I downloaded a fresh copy to make sure I was current and exported my sprite files... but I am coming up a few sprites short on the page.



Is there a tool to do the whole "New style" sprite sheet? or are these images edited by hand? I want to make sure I'm doing the correct thing because I intend to start doing some more serious hacking in the near future.
