Installation

The following section explains how to install MinUI using macOS, without having to download any additional tools. These instructions currently only work with 64GB microSD cards. Other sizes require additional partitioning steps that this guide does not cover yet.

Prerequisites

• A new 64GB microSD card from a reputable brand
• The offical Anbernic RG355XX firmware (35XX-64GB230309EN.IMG)
• A MinUI release
• An administrator user account
• Full Disk Access for the app Terminal.app

Install MinUI

1. Connect your microSD card to your Mac
2. Start the app Terminal
3. Run the command diskutil list and identify your microSD by looking at the SIZE column. It is /dev/disk4 in this example.
4. Run the command diskutil unmountDisk /dev/disk4
5. Unzip the RG35XX firmware to your desktop and then run the command cd ~/Desktop in the Terminal
6. Run the command sudo dd bs=1m if=35XX-64GB230309EN.IMG of=/dev/disk4 to flash the firmware onto your microSD. Enter your user account password if prompted. Wait.
7. Run the command diskutil list again and identify the largest partition on your microSD by looking at the SIZE column. It is /dev/disk4s4 in this example. Note that it differs from the previous path!
8. Run sudo diskutil eraseVolume FAT32 ROMS /dev/disk4s4 to format that partition as FAT32 with the name ROMS. Enter your user account password if prompted. Wait.
9. You should now have a misc and a ROMS disk connected to your Mac. If you don't then try reconnecting your microSD card to your Mac.
10. Unzip the MinUI release to your desktop
11. Copy dmenu.bin to the root of the misc disk. Copy MinUI.zip and the Bios, Emus, Roms, Saves, Tools folders to the root of the ROMS disk. Optionally, follow the additional instructions in the MinUI README if you wish.
12. Finally, to remove dotfiles created by macOS on your microSD, run:

dot_clean -m /Volumes/misc
rm -fr /Volumes/misc/.feventsd
rm -fr /Volumes/misc/.Spotlight-V100
rm -fr /Volumes/misc/.Trashes

dot_clean -m /Volumes/ROMS
rm -fr /Volumes/ROMS/.feventsd
rm -fr /Volumes/ROMS/.Spotlight-V100
rm -fr /Volumes/ROMS/.Trashes

Done. Insert your microSD to your RG35XX and boot it up!
