Ever since the Miyoo A30 was released, we’ve been hoping to see custom firmware options made available. It’s immediately apparent that Miyoo has a lot of work to do on the software side of things, as it’s just an underwhelming out-of-box experience.

There are a few options that try to right the wrongs, but nothing that entirely replaces the stock firmware. However, that’s all changed thanks to the recent release of MinUI, and we’ll walk you through the steps to install MinUI on the Miyoo A30.

As the name suggests, MinUI doesn’t try and throw a bunch of new features into the mix. Instead, it takes a minimal approach, with a lightweight interface and letting you just jump in and start playing retro games. With that being said, let’s dive in.

How To Install MinUI on Miyoo A30

This first section is for those who want to install MinUI on Miyoo A30 if you grab one that includes a microSD card. However, something that we recommend is to double-check the microSD card itself. If there isn’t any branding on it, you’ll probably want to copy everything over to one from a reputable company.

It’s as easy as just inserting both microSD cards into your computer and formatting the new one. Then, copy all of the files from the “old” one to the new microSD card before proceeding. Doing so aims to cut down on the chances of your microSD card failing, as retro handheld companies use unbranded and cheap cards with their handhelds.

With that in mind, here’s how you can install MinUI on the Miyoo A30:

  1. Download and extract the latest MinUI release from GitHub.
  2. Remove the microSD card from your Miyoo A30 and connect it to your computer.
  3. Open the extracted MinUI folder.
  4. Copy the MinUI.zip and miyoo folder to the microSD card.
  5. If prompted about duplicate files, make sure you select Replace.

  6. Open the Bios folder.
  7. Make sure that you have the following BIOS files in the corresponding folders:
    • FC: disksys.rom
    • GB: gb_bios.bin
    • GBA: gba_bios.bin
    • GBC: gbc_bios.bin
    • MD:
      • bios_CD_E.bin
      • bios_CD_J.bin
      • bios_CD_U.bin
    • PS: psxonmpsp660.bin
  8. Eject your microSD card and put it back into your Miyoo A30.
  9. Power on your A30.

After a moment or two, you should see a loading screen that says “Installing MinUI.” Just hang tight as you’ll be taken right to the main screen so you can start playing games.

**Editor’s Note**

As it turns out (thanks Shaun), you don’t actually need to move the A30 stock firmware to the microSD card before installing MinUI. The guide has been updated to reflect as such.

Additionally, if you are using a microSD card that’s 32GB or smaller, you can skip steps the formatting steps in the section above.
