404 Errors

[eluser]TheFuzzy0ne[/eluser]
Can you not extend the CI_Exceptions class in /system/libraries/Exception.php and then override the show_404 method?

Alternatively, you can rewrite the error_404.php file to do what you want it to. I would suggest that you don't pass it to another controller however, as that has already been done. You would need to write a library or some helper functions to do what you want.
