What is it?

This is NextUI for Anbernic RG XX devices (rc4 was not released publicly). It is based on NextUI 6.14.0.

NOTE: This port is not official yet - please file bug reports only on this GitHub repo, or in the #h700-stuff channel on Discord.

Which devices are supported?

  • RG28XX
  • RG34XX
  • RG34XX SP
  • RG35XX+ and RG35 XX 2024
  • RG35XX Pro
  • RG35XX SP
  • RG35XX H
  • RG40XX H
  • RG40XX V
  • RG Cube XX
  • RG SP

The original RG35XX is not supported.

TrimUI Brick, Brick Pro, Smart Pro and Smart Pro S are also supported. You can swap your NextUI card between all supported devices.

How to install fresh?

You need:

  • one of the above devices.
  • the Anbernic stock OS that came with your handheld or StockMod OS already working from your 1st SD card slot.
  • a second SD card for NextUI and your games

You can also use BaseOS - a drop-in minimal replacement for the stock OS that boots up ultrafast (under 7 seconds) and supports all features. Disclaimer: BaseOS is not associated with NextUI and it is optional to use.

Steps:

  1. Download and unzip the contents of the zip file to an empty SD card formatted as FAT32 or exFAT using the MBR partitioning scheme. This is your Next UI card.
  2. If you want, you can also copy your games and bios to the Roms/ and Bios/ folder now.

It should look like this: image

If you're using BaseOS, skip to step 4. If you're using stock or stock mod OS, you need to do one extra step:

  1. You will see an h700/ folder and a file dmenu.bin inside it. Copy just this file to the root of the NONAME or Roms partition of your Stock OS card (not inside the Roms folder!).

IMPORTANT: make sure you are NOT using "MU style" theme -- change your theme to "old style" (default). Otherwise, NextUI will not start.

  1. Insert the stock OS (or BaseOS) card in your 1st SD card slot, and the Next UI card in the 2nd SD card slot, then power on your handheld.

NextUI should start installing and then boot up.

If you already copied your games, they'll show up. If not, power off your device, take the NextUI card out and copy your games. Then plug it in again, reboot your device and enjoy.

How to update?

Unzip the contents of the NextUI-xxx-h700-rcX-all.zip file to your NextUI card. Overwrite (/merge) the existing files.

If you like the terminal you can do:

unzip -o <drop the NextUI release zip here> -d <drop your SD card here>

What works and what doesn't?

Everything works, except:

  • No Pak Store
  • No Updater

Yes, these will be added for final release.

Bug reports

You can either come to NextUI discord in the h700-stuff channel, or create GitHub issues (preferred for repeatable bugs that specific to NextUI on Anbernic). I am a hobbyist doing this in my free time so support is not guaranteed. However, it would be helpful to receive bug reports on what works and what doesn't.
