.er

General Info
The .er file is a file format used by Newer SMBW for music and sound. It is identical to a .brstm file, just with a different file extension. There is a small joke hidden here. The folder the files is in is called 'new', and the files are .er files. The joke here is that it makes 'newer'.

How To Use The .er File
You can use a .er file in BrawlBox/BrawlCrate by changing the file extension to .brstm, as the .er file is a copy of the .brstm file format. The file should work perfectly unless the file itself was damaged.
