About sample_demo.rlyt In order to view the sample layout data, the font data that is referenced by the layout data must be generated. To generate font data, run the batch file (make_sample_font.bat) located in the same folder as the layout file. NintendoWare and the font converter package must both be installed correctly in order for the batch file to execute correctly. If the font is generated successfully, a file named "sample_font.brfnt" is generated in the same folder as the batch file.
