+Most retro-gaming console software emulators are able to run game ROMs
+directly.
+
+However, the Game Boy Advance an PS1 emulators do require an
+additional BIOS file in order to emulate all or some of the game ROMs.
+
+## GBA
+
+If you launch a GBA game in the first place, you will get this screen:
+
+![GBA BIOS](/assets/images/GBA_BIOS.png)
+
+This means that you will need to install on the **FunKey S** a BIOS
+file with the right name, size and MD5 checksum before you can
+actually play.
+
+Here is the procedure:
+
+| **Display**                                                          | **Action**                                                                                                                  |

+| ![Connection PC](/assets/images/Connection_PC.png)                   | Connect the **FunKey S** to your computer using the provided micro USB cable, then open it to turn it on                    |
+| ![RetroFE](/assets/images/RetroFE.png)                               | At the launcher's main screen (example here with RetroFE), press the **MENU** key                                           |
+| ![Mount USB](/assets/images/Mount_USB.png)                           | Press the **UP**/**DOWN** keys until you see "**MOUNT USB**"                                                                |

+| ![Eject USB](/assets/images/Eject_USB.png)                           | "**EJECT USB**" is now displayed instead, now go to your host computer and open a File Explorer window                      |
+| ![USB Drive](/assets/images/USB_Drive.png)                           | You should see the **FunKey S** appear as an USB drive on your computer in the File Explorer (example here with Windows 10) |
+| ![Copy ROM](/assets/images/Copy_GBA_BIOS.png)                        | Drag & drop the _**gba_bios.bin**_ BIOS file into the _**Game Boy Advance**_ folder in this USB drive on your computer      |
+| ![Eject Drive](/assets/images/Eject_Drive.png)                       | Eject cleanly the USB drive from your computer                                                                              |
