How to Use RetroPie with a USB

Retro gaming enthusiasts often find themselves in situations where they want to play their favorite classic games on modern devices without the hassle of cables and adapters. This is where RetroPie comes in - a free and open-source emulator that allows you to play retro games on your Raspberry Pi or other compatible devices. In this tutorial, we'll explore how to use RetroPie with a USB adapter.

Before we begin, it's essential to note that the WiFi dongle used in this project supports IEEE 802.11b/g/n protocols with speeds up to 150Mbps. The Tenda W311MI USB Adapter is the specific model used here, but you can opt for any compatible adapter suitable for your needs.

To connect a Raspberry Pi 2 or older devices without an on-board WiFi adapter, we need to use an external USB type WiFi dongle. If you're familiar with setting up WiFi on Raspberry Pi 3 using its onboard adapter, you might be surprised to know that the process is slightly different when using a WiFi dongle.

To get started, ensure your Raspberry Pi is connected to a power source and has a micro-USB cable connected to it. Next, insert the USB WiFi dongle into one of the available USB ports on your device.

Now, let's move on to the steps involved in setting up RetroPie with a USB adapter. First, you'll need to install the RetroPie software on your Raspberry Pi. This can be done by downloading the latest version from the official website and following the installation instructions provided.

Once installed, run the command `sudo raspi-config` to configure your Raspberry Pi's settings. Here, you'll need to enable Bluetooth support under the 'Interfacing Options' menu.

Next, connect your Xbox controller to your Raspberry Pi using a USB cable. Make sure it's listed as a trusted device by running the command `bluetoothctl` and replacing MAC_ADDRESS with the actual MAC address of your controller. Note down this address as we'll need it later.

Now, let's start scanning for available Bluetooth devices by running the command `sudo bluetoothctl`. Put your Xbox controller into Pairing mode and wait for it to appear in the list of devices.

To disable Enhanced Re-Transmission Mode (ERTM), run the command `echo 'options bluetooth disable_ertm=Y' | sudo tee -a /etc/modprobe.d/nf`. After rebooting your Raspberry Pi, start Bluetooth Tools with the command `sudo bluetoothctl` and follow the prompts to connect your Xbox controller.

With these steps completed, you should now be able to play retro games on your Raspberry Pi using RetroPie. Simply insert a game cartridge into your USB adapter, navigate to the 'RetroPie' menu, and select the desired game from the list of available titles.

In conclusion, setting up RetroPie with a USB adapter is a relatively straightforward process that can help you enjoy your favorite classic games on modern devices without the hassle of cables and adapters. With this tutorial, we've covered the essential steps involved in connecting an Xbox controller to your Raspberry Pi using Bluetooth and configuring it for use with RetroPie. Happy gaming!
