Mario Kart Wii Gecko Codes, Cheats, & Hacks

So I've been trying to make a Wii Virtual Console WAD for the NES Dr. Mario. I got basically everything to run perfectly... expect for the fact that the banner still says "Double Dragon" and also the release year is wrong. I can't find a way to edit the banner.brlyt file, I tried using Wii Layout Editor, yet it gives me an error when I try to load the file (see picture). I extracted the layout banner.brlyt file from CustomizeMii if that's important.

Can someone please help me!

With any file (as long as you have the proper documentation), you could always use a Hex Editor. Though this may not be very practical if brlyt files are very complex.
