TrimUI Smart Setup Guide

Recommended Accessories

  • MicroSD Card: 128GB or 256GB (any of these would work well with the platforms this plays on).
  • UGREEN SD Card Reader MicroSD Card Reader
  • Charger: UGREEN 65W Charger (charge via USB-A connector)

Preparation

  • Clone SD card: These devices' SD cards are unbranded, of poor quality, and prone to malfunctioning. It is recommended that you change them as soon as the gadget is delivered. Click here to learn how to clone your SD card. Before using this advice, I strongly advise doing so.

Stock Setup Guide

It is assumed in this setup instruction that you already have an SD card from the device.

Getting the most recent firmware is the first thing you should do, and you can do so here. SD_patch and SD_image_recovery are the first two files you wish to download.

The SD_image_recovery zip file should be extracted. Now, insert a blank, branded SD card into your computer. Since this will only be used temporarily, you can use any SD card you previously used with this device.

After downloading the portable version of Rufus, launch it.

Please verify that the device is your SD card; it should have the exact dimensions. To access the picture we extracted from the SD_image_recovery package, click SELECT. Then click START.

After it's finished, insert the SD card into your TrimUI Smart, switch it on, and safely eject it.

Watch the bottom left LED; it will flash briefly before ceasing. After it stops, you can eject the SD card and turn off the device.

You can set aside the temporary SD card since we won't need it anymore. Attach the device's original SD card to your computer.

Extract the sd_patch zip file, which is the other one we downloaded.

Overwrite whatever it asks for and copy all extracted folders (Emus, RetroArch, Roms, etc.) onto the SD card.

You are now entirely prepared! However, you can proceed to the next section to upload more ROMs or BIOS files.

Adding ROMs & BIOS

Attach your PC to your SD card.

If you navigate to the Roms folder, you should notice a number of folders for every system the device supports.

Moving your ROMs for each system into the appropriate system folder should be prettyself-explanatory at this stage.

To access the BIOS, navigate to the RetroArch folder, followed by system and. retroarch. You can save your BIOS files inside this folder.

Custom Firmware Options

The stock firmware that we set up above can be replaced with custom firmware. I recommend using a different, brand-new SD card to test out any custom firmware and keeping your stock on hand in case you decide to go back.

MinUI

With a brand-new, branded SD card and your own ROMs and BIOS files, this setup instruction assumes you want to start from scratch. MinUI will be installed for this tutorial.

You can download the most recent version, which includes the base and extras zip files, by visiting the MinUI GitHub page here.

As I suggested above, attach your branded SD card to your PC. If you still need to get Rufus, download it.

Before we format the SD card, launch Rufus. You can rename the volume label if you want to and change the boot selection to nonbootable. Verify that the file system is either Large FAT32 or FAT32. After that, click Start and select "Okay" for any alerts.

After that, extract the base zip file we previously downloaded. Next, move the MinUI.zip files and the Trimui folder to the SD card's root.

After safely ejecting it, pop it into your off TrimUI Smart and activate it. After installing MinUI, you should see a screen with only the Tools option. After turning off the device, remove the SD card and replace it on your computer.

The extras zip file should be extracted. Then, copy and paste all of the folders you just extracted—Bios, Emus, Roms, Saves, etc.—onto the SD card's root. If it asks, overwrite anything.

You have finished configuring MinUI! To add ROMs and BIOS files, proceed as directed.

Adding ROMs & BIOS files to MinUI

Attach your PC to your SD card.

If you navigate to the Roms folder, you should notice a number of folders for every system the device supports.

Moving your ROMs for each system into the appropriate system folder should be fairly self-explanatory at this stage.

Go to the Bios folder to access BIOS. You'll need the following for BIOS files:

  • MGBA: gba_bios.bin
  • PCE: syscard3.pce
  • PKM: bios.min
  • SGB: sgb. bios

For legal reasons, I can't provide the location of these files, but you should be able to find them by searching for the file name on Google.
