Replacing Stages (some not working)

[Klophunk]

Okay, so I use Riivolution for all of the brawl hacks, but for some reason whenever I try to replace either Flat Zone, Pictochat, New Pork City or Onett, it won't work. There are probably other stages but these are the ones I know for sure. Either no effect will have taken place or the stage is just a black abyss. Can anyone help or explain to me what's going on?

Any help at all? I just tried replacing Pictochat with the new KC:MM Stadium but I can't even get passed the loading screen. :(

Both the stages need an _en at the end. Riivolution needs the _en at the end of the files that it.

Thank you so much! It works perfect.

Yeah I was wondering about that myself, but now that I know I shouldn't have any problems.
