.rsd Files

.rsd files are the files used for Wii Sports Resort Miis.

How to Create .rsd Files
Download RSDmaker from the Discord server. Then, drag and drop your .RCD files onto the RSDmaker. You now will have an .RSD file that you can use in Wii Sports Resort.

Converting from RSD to RCD
Download HxD Hex Editor from the Discord server. Then, open up your .RSD file in HxD. Delete the last two bytes of the data from the .RSD file. Save the file as .RCD.
