How to add box art in Miyoo Mini?

While adding box arts in Miyoo Mini is easy to do, creating them need a intermediate guide. This guide is inspired when I answered how to add box art in RG35XX, so expect similarities. Box art, again, is a thumbnail image representing your games. Many people need box arts to tell which game it is, and considering that the older we are, the worse our eyes can be. That’s why I think it’s a bliss to include box arts into our retro handheld device.

Make sure you read my Miyoo Mini Onion guide.

What you need

  • The latest version of Skraper
  • The latest version of ImageMagick
  • List of box arts for retro games (adding manually)

Adding box art manually

If you don’t like to download anything, you would like to add box art manually. If you use Onion with your Miyoo Mini or Miyoo Mini Plus, it is very easy to add box arts manually. Here is the step-by-step guide:

  • Download box arts manually, either from Archive or libretro
  • Insert your SD card, navigate to %ROMROOTFOLDER%\Imgs. If there is no folder with that name, create one
  • Depending on where you download box arts from, you must resize to match the Miyoo Mini’s resolution. Continue to bulk resize all images
