MinUI on a TrimUI Brick

MinUI: a minimalist retro-gaming launcher

MinUI is a minimalist user interface and libretro frontend for retro handhelds. The interface is simple, functional and stylish, with a premium feel. Behind the clean design is a broad set of features for a fast and pleasant retro-gaming experience.

MinUI on the TrimUI Brick

MinUI suits the TrimUI Brick well. The clean interface matches the premium hardware experience and makes it easy to start a game quickly.

Key features

  • Clear file view: hidden files and unwanted extensions are automatically hidden.

  • Quick access while playing: through a consistent in-emulator menu you can manage save states and disc switching, among other things.

  • Smart power management: the system goes into sleep mode after 30 seconds of inactivity and shuts down completely after two minutes.

  • Automatic resume: after restarting, you can carry on straight where you left off.

  • Flexible storage: the same SD card can be used on multiple supported devices from different manufacturers.

  • Save states from the launcher: press X in the launcher to load manually created save states directly.

This installation guide was written for the TrimUI Brick, but it also works with among others:

Installation

1. Download the required files

Go to the official MinUI releases on GitHub and download:

  • MinUI base .zip

  • MinUI extras .zip

2. Prepare the files

Unpack both zip files and create a new folder for your device. For the TrimUI Brick, you can name this folder, for example, minui-for-trimui-brick.

From the base folder, copy the following folders and files into this new folder:

  • Bios

  • Roms

  • Saves

  • TrimUI

  • README.txt

  • em_ui.sh

  • MinUI.zip

Then copy everything from the extras folder into the same folder and overwrite files when prompted.

3. Format the SD card

Format the SD card on your computer as FAT32 and name the card MinUI.

On macOS, you can do this via Finder. On Windows, you can use Disk Management for this. Back up any files that are still on the SD card beforehand.

4. Copy MinUI to the SD card

Copy the contents of the folder minui-for-trimui-brick to the formatted SD card.

5. Install MinUI

Insert the SD card into your TrimUI Brick and start the device. Let the installation process run all the way through.

6. Add games

Place your own ROM backups or ROMs from legal, trustworthy sources in the relevant folders, for example SNES for Super Nintendo games. Move these folders to the folder Roms on the SD card.

You can also check games on itch.io for new and legal homebrew games.

7. Start your handheld

Put the SD card back into the TrimUI Brick and explore the clear MinUI interface.

Always make a backup before formatting an SD card or replacing system files.
