The V90S features two TF card slots:
- TF1 Slot: This slot is for the system's operating system and preloaded games. The 64GB card included with your console should be inserted here.
- TF2 Slot: This slot is for additional game ROMs and media. You can insert an additional TF card (up to 256GB) into this slot to expand your game library.
Gently push the TF cards into their respective slots until they click into place. To remove, push again until they spring out.
Operating Instructions
1. Powering On/Off
- To power on, open the clamshell and press and hold the power button located on the side of the console until the screen illuminates.
- To power off, navigate to the system menu and select the shutdown option, or press and hold the power button until the device powers down.
2. Basic Navigation
Use the D-pad for directional navigation through menus and game selections. The A, B, X, Y buttons are used for selection and actions within games. The START and SELECT buttons perform various functions depending on the game or menu context.
3. Playing Games

This image highlights the extensive compatibility of the Powkiddy V90S, capable of running games from over 20 different emulators, including popular systems like PSP, Dreamcast, PS1, N64, and various classic consoles.
The console comes with a 64GB TF card preloaded with over 10,000 games across more than 20 systems. To play a game:
- Navigate to the desired emulator or game list from the main menu.
- Select the game you wish to play using the D-pad and A button.
- The game will load. Some games may require specific button configurations or settings adjustments within the emulator menu.
Ethical Note: Preloaded games are for hardware testing purposes. Users are encouraged to own original copies of games they play.
4. Adding More Games (ROMs)
To add more games, you will typically need to transfer ROM files to the TF2 card. Connect the TF2 card to a computer using a card reader. Organize your ROMs into appropriate folders for each emulator (e.g., "GBA" for Game Boy Advance games, "PS1" for PlayStation 1 games). Once transferred, reinsert the TF2 card into the console, and the system should detect the new games.
5. Open-Source Operating System
The V90S comes with a stock open-source Linux OS. For advanced users, the console supports alternative firmware like ArkOS (for potentially better PSP performance) and RetroArch (for advanced shaders and rewind features). Custom themes are also supported. Refer to online communities and forums for detailed instructions on installing custom firmware.
6. Connectivity
- USB-OTG: The USB-C port supports USB On-The-Go (OTG), allowing you to connect external controllers or other USB peripherals via an adapter (not included).
- HDMI Output: The console supports HDMI output via a separate adapter (sold separately), allowing you to connect it to a larger display.
