The Miyoo A30 arrived as something of a stop-gap measure in handheld releases. While Anbernic has been churning out devices almost monthly throughout 2024, Miyoo has remained fairly quiet.

The A30 emerged in April 2024 as a direct competitor to the Anbernic RG28XX. Both devices are small, horizontal, and pocketable, but their software experiences and hardware modules differ. Initially, the stock A30 experience can feel underwhelming to downright janky, but with a tiny bit of effort, it transforms into a go-to for small form factor emulation.

The Miyoo A30

Backup Stock Firmware

• Backup Your Data: Before you start exploring custom firmware options, take a moment to back up your stock card image along with any important files you may have added along the way.

• Stock Firmware: If needed or preferred, the stock firmware for the Miyoo A30 can be downloaded from the official Miyoo website here.

  Backup Using Win32DiskImager

  1. Fire up Win32DiskImager: Click on the little folder icon under the “Image File” section and choose where you want to save the image output, remembering to add a .img file extension to your chosen filename.
  2. Choose the image: Choose the device drive you want to clone. *Be very careful during this process, or you can inadvertently erase entire drives you didn’t intend to.
  3. Read Only: Ensure that the box “Read Only Allocated Partitions” is highlighted, otherwise you will copy over any blank sectors of the drive along with the data.
     
  4. Create the Image: Click on the “Read” button and the software will begin creating the backup image file to the location you chose.

Write the contents of the stock SD card to an .img file

• Format Your SD Card: Format your new blank SD card to FAT32 to ensure compatibility with the custom firmware.

Custom Firmware

Custom Firmware Options

• • Spruce: Per the devs, Spruce isn’t really a new OS, but rather “We think spruce is best described as being a beautification and optimization of the stock Miyoo OS that cleans up bloat, optimizes performance and focuses on aesthetics.” It’s very popular for its ability to mimic the OnionOS experience from the Miyoo Mini+.

  • MinUI: As the name would imply, MinUI is a minimalist CFW available for a variety of handhelds, including the A30. For a small device such as this one, some users may want as minimal a UI experience as possible. If all you’re looking for is to find your title and get to playing it in a competent manner, then MinUI has you covered.
    

  • Better Than Nothing (BTN): BTN is an under-the-hood overhaul of the Miyoo stock OS. It includes all the optimizations and pre-configured settings most users would want for an enjoyable emulation experience while keeping to the familiarity of the stock experience that some users may prefer.

Wrap Up

So there you have it. The Miyoo A30, like so many other devices, is a great handheld so long as you apply the software support the emulation community has given it. Which CFW is right for you comes down to personal preferences. I like Spruce on this device, as I think it runs well and provides a familiar Miyoo experience that I like on their other devices, without all the bugs that haven’t been sorted with the stock firmware. The firmware process on this device is relatively painless, so get out there with your newly capable CFW sporting pocketable and get gaming.
