Is anybody able to have a good experience with HDMI output with SpruceOS? Either the image is massively stretched, or it appears as a small box in the corner of the screen (possibly depending on which monitor it's plugged into?). Also I have to fully reboot the console with HDMI plugged in just to get it to show up on the monitor.

I've also been having issues with the home key not working during games (but fine in the SpruceUI), but this may be an unrelated issue.

Is there another firmware with better HDMI functionality? Will this ever be fixed?

Been glancing between the 34xxsp and the Flip V2 on AliExpress and just found out that the AliExpress is indeed the updated hinge from miyoo so I finally placed my order for the black flip and will be comparing it against the New metallic blue 34xxsp too see who’s screen i prefer and buttons and everything it seems miyoo is my match but that screen saturation looks so good on the anbeenic. If anyone has any advice be much appreciated also is 68 a good price too pay shipped for the new 2.1 hinge?

It looks like hinge replacements are back in stock for miyoo and I have a $5 coupon.

My hinge hasn’t broken yet, but based on everything I’ve seen I feel like it’s bound to happen sooner or later. Should I just preemptively buy the shell replacement?

I’m running Surwish OS. Is there any hope of streaming lightweight 2D indie games from a Steam Deck to the Miyoo Flip? Is Moonlight possible or are there any other options?

I recently bought a Miyoo Flip V2 on Amazon and it did not come with any game on the SIM card. I’ve heard those are really bad and bought a new one and sim reader. Ive been going on YouTube for tutorials on how to set it up. I found one using MIN UI, it Said it was an easy to use emulator. I downloaded the files from the tutorial and put them on the card. I then put it in the device. it would boot up for a second then say loading then turn off completely. I tried charging it, did not solve problem. What do I do now?

My question is why keep Buying Miyoo Flip when you know the hinge is not good and will keep breaking ,instead of buying the Anbernic 35/34xsp?

I bricked my flips after running gamma loader, and notice some people had the same thing happen to them. Im too lazy unbrick it aswell. So question is, how many of us are just sitting on bricked flips?

If you are using Knulli (Scarab) on the Miyoo Flip 2, you have probably noticed a major problem: editing retroarch.cfg directly or changing keybinds within the RetroArch Quick Menu does not work. Knulli generates a fresh configuration every time you launch a game, completely overwriting your custom inputs.

To bypass this behavior and lock in your own custom controls - like assigning a dedicated Turbo Mode modifier without the need to create custom overrides - you must inject the commands via your master knulli.conf configuration file.

Step 1: Locating the File

The file you need to modify is named knulli.conf. How you access it depends entirely on whether you run a single-card or dual-card setup:

• For a 2-SD Card Setup (ExFAT Card in Slot 2): Shut down your Miyoo Flip 2, remove the second SD card, and insert it into your computer. The storage partition is formatted to ExFAT, allowing you to access it directly:
  • On a Mac: /Volumes/[SD card name]/system/knulli.conf
  • On a Windows PC: [Drive Letter]:\system\knulli.conf (If the drive letter does not appear automatically in Windows, open Disk Management, right-click the large exFAT partition, and select Change Drive Letter and Paths to assign one manually.)
  • On a Linux PC: /media/[username]/[SD card partition name]/system/knulli.conf
• For a 1-SD Card Setup: You cannot simply plug the SD card into a Windows or Mac computer. In a single-card setup, the user directory resides on a Linux ext4 partition that is completely invisible to Mac and Windows file systems. Instead, you must keep the card inside the Miyoo Flip 2, boot the device, and connect it to your local Wi-Fi network. You can then access the file wirelessly using one of two methods:
  • Network Share (Samba): Open your file manager and navigate to \\KNULLI\share\system\knulli.conf
  • SSH / SFTP: Connect using an SSH client or SFTP tool (like WinSCP or Cyberduck). Use the device's local IP address with the username root and password linux. The file is located at the absolute system path: /userdata/system/knulli.conf

Step 2: The Rules for Injection

To make Knulli forward a command permanently into RetroArch, you must prefix every line with global.retroarch..

When working inside Linux backends like Knulli, you cannot use word labels like "l3". You must use the numerical button ID associated with your controller's firmware layout. On the Miyoo Flip 2, button 11 represents a physical down-click on the left analog stick (L3), and button 10 represents the hardware M button.

Step 3: Configuration Block

Paste the following block at the very bottom of your knulli.conf file.

Note: The keybind values provided below are purely suggestions based on a comfortable layout. You are free to change any of the numerical button IDs to match your own personal controller mapping preferences.

knulli.conf:

# --- TURBO CONFIGURATION ---
global.retroarch.input_turbo_mode = "1" # Turbo Mode 1
global.retroarch.input_player1_turbo_btn = "11" # Turbo Hotkey (L3)

# --- MENU & NAVIGATION ---
global.retroarch.input_menu_toggle_btn = "10" # Menu Hotkey (M button)
global.retroarch.input_menu_toggle_gamepad_combo = "2" # Menu Combo (L3 + R3)
global.retroarch.input_quit_gamepad_combo = "4" # Quit Combo (Start + Select)
global.retroarch.input_menu_toggle = "nul" # Disable keyboard menu toggle

# --- CORE GAMEPLAY CONTROLS (FAST FORWARD & REWIND) ---
global.retroarch.input_hold_fast_forward_btn = "7" # Fast-Forward Hotkey (R2)
global.retroarch.input_hold_fast_forward = "nul" # Disable keyboard fast-forward
global.retroarch.rewind_enable = "true" # Enable rewind backend
global.retroarch.input_rewind_btn = "6" # Rewind Hotkey (L2)
global.retroarch.input_rewind = "nul" # Disable keyboard rewind
global.retroarch.rewind_granularity = "5" # Rewind frame step rate

# --- UNUSED / DISABLED KEYBOARD HOTKEYS & BUTTONS ---
global.retroarch.input_ai_service = "nul" # Disable AI text hotkey
global.retroarch.input_ai_service_btn = "nul" # Disable AI button
global.retroarch.input_enable_hotkey = "nul" # Disable keyboard master hotkey
global.retroarch.input_enable_hotkey_btn = "nul" # Disable button master hotkey
global.retroarch.input_exit_emulator = "nul" # Disable keyboard exit
global.retroarch.input_exit_emulator_btn = "nul" # Disable button exit
global.retroarch.input_load_state = "nul" # Disable keyboard load
global.retroarch.input_load_state_btn = "nul" # Disable button load
global.retroarch.input_reset = "nul" # Disable keyboard reset
global.retroarch.input_reset_btn = "nul" # Disable button reset
global.retroarch.input_save_state = "nul" # Disable keyboard save
global.retroarch.input_save_state_btn = "nul" # Disable button save
global.retroarch.input_screenshot = "nul" # Disable keyboard screenshot
global.retroarch.input_screenshot_btn = "nul" # Disable button screenshot
global.retroarch.input_shader_next = "nul" # Disable keyboard next shader
global.retroarch.input_shader_next_btn = "nul" # Disable button next shader
global.retroarch.input_shader_prev = "nul" # Disable keyboard prev shader
global.retroarch.input_shader_prev_btn = "nul" # Disable button prev shader
global.retroarch.input_state_slot_decrease = "nul" # Disable keyboard slot down
global.retroarch.input_state_slot_decrease_btn = "nul" # Disable button slot down
global.retroarch.input_state_slot_increase = "nul" # Disable keyboard slot up
global.retroarch.input_state_slot_increase_btn = "nul" # Disable button slot up

How to Use the Turbo Mode In-Game

Since this block configures input_turbo_mode = "1", it uses Classic Toggle functionality:

1. Boot into any game.
2. Hold your Left Stick Click (L3) (or whatever button you chose to replace 11) and tap an action button (like A).
3. Release both. Button A will now autofire continuously on its own.
4. Hold your turbo modifier and tap A again to clear the toggle and return to standard operation.

Expected Button Mapping Changes

Once you save the file, your active button mappings will change to the following layout:

• Turbo Toggle Modifier (L3 Click): Used exclusively to turn rapid-fire on or off for your target gameplay face buttons.
• Quick Menu Toggle (M Button): Tapping the hardware M button will instantly open or close the RetroArch Quick Menu.
• Alternate Menu Toggle (L3 Click + R3 Click): Pressing down on both analog sticks simultaneously will also open or close the RetroArch Quick Menu.
• Fast-Forward (R2 Trigger): Pressing and holding the right rear trigger will accelerate the game speed; letting go drops it back down to regular full speed.
• Gameplay Rewinding (L2 Trigger): Pressing and holding the left rear trigger will actively reverse the game frame by frame in real-time.
• Emulator Exit (Start + Select): Pressing these two face buttons together will instantly quit out of the emulator and return you to the Knulli frontend.
• Disabled Actions: Traditional keyboard hotkeys, standalone emulator resetting buttons, and accidental button-combination save/load triggers are entirely muted to prevent accidental inputs during intensive gaming sessions.

Hello everybody !

What is the maximum charger I can use with my new miyoo Flip v2.1?

I have one old Samsung S6 charger (I use it to recharge my PSP), one 45W and one 100W. Which one do you recommend?

Thanks !

I’ve followed all the steps in the guide and even consulted the YT video that was posted a while back and neither have been able to solve my issue.

Gammaloader seems to work just fine, but no matter what I try after flashing the SD and entering it into the right slot, I am unable to boot into Knulli. This is really frustrating me and if anyone has any ideas I would greatly appreciate it.

I’m looking to install a different OS. I’m currently leaning toward MinUI as I just want to play games without too much bloat. What are you currently using?
