RetroArch - Fix missing thumbnails and boxart!

This is a video guide explaining how to fix missing thumbnails or boxart within the RetroArch application and what to do when the automatic thumbnail updater doesn't download your thumbnails. It covers both how to fix missing thumbnails for games that are mislabeled and do not match up with the RetroArch libRetro thumbnail database (http://thumbnails.libretro.com/) and also how to go about adding thumbnails for games that aren't in the database at all.
Remember:
-If your displayed game name doesn't match the thumbnail database name, be sure to change the display name in RetroArch for that game to match up with the corresponding database name (do not change the actual file name where you have your rom located).
-If your game isn't in the database and you are locating boxart from the web, be sure to change your thumbnail image type by re-saving the image as a .png in a paint program (do not directly change the file type when saving it from the web or you will run into issues).
-If your game is not in the database AND for whatever reason the Desktop Menu is not letting you drag and drop .PNG files into the little box there is one final method:
1) Locate your thumbnails folder wherever your RetroArch is installed (for me this is: This PC\Local Disc C\Programs\RetroArch\thumbnails
2) You will see all of your platforms listed here
3) Drag and drop your custom .PNG image into the appropriate folder
4) Go into the folder and rename the custom image the EXACT same name as the RetroArch display name (just copy and past the title from Desktop Menu to be exact)
5) It should then show up if the image type is correct and matches the display name perfectly.

IMPORTANT: Paint works fine for a simple copy paste but if you are doing your own customization or background creation, you may want to use a different program because Paint deletes the image's alpha channel which handles opacity/transparency. For a quick copy/paste I have never had this cause any issues but for any kind of editing you may want to try Paint.Net or something else (any other image program should work just fine).

http://thumbnails.libretro.com/

IF this website is down or if one of the consoles you are accessing is being worked on and doesn't show any of the games currently, I would recommend using Way-Back-Machine to access the database from a previous date when it worked. For example, this link right here should work if the above link has anything down:
