Here's the Story:
Several months ago upon paying closer attention to the revised GoodTools License I discovered I was illegally providing RomCenter datafiles based on these renaming utilities. I immediately removed them from my site and requested permission from Cowering to continue offering these dats to RomCenter users.
Cowering posted the following response to my query in his Forum:
"No datfile will ever be as good as a goodtool. I'm no longer willing to license derivatives that are not in someway superior to my tools. A Goodtool (with a frontend if needed), is the best overall solution to renaming."
That says it all. No more datafiles.
