Wii Layout Editor is a program created by Gericom. It is able to view certain types of file extentions, such as BRLAN and BRLYT. If the program does not start, it means that the OpenGL version is not supported.
Wii Layout Editor is not able to edit the .brlan (Wii banner animation) files. It is just for read and edit .brlyt (Wii banner layout) files.
If you want to use BENZIN, convert the .brlan to .xmlan, not .xmlyt. Converting to .xmlyt requires the .brlyt to convert.
