I just released a new update that should make The SMDH even easier to use. File associations has been added, when opening a file it'll onlly show .smdh by default. You can also open .bin file format for icons created in 3DS banner maker. Importing images will only show .png files. Lastly, you can also save as a .bin file as well.
