How do I access RetroPie from my computer?

To access RetroPie from your computer, you need to connect both devices to the same local network. First, find the IP address of your RetroPie by going to the RetroPie menu and selecting "Show IP." Then, open a file explorer on your computer and enter the IP address in the address bar using the format "smb://<IP address>". You should now be able to access the RetroPie's file system and transfer files between your computer and RetroPie. Additionally, you can use an SSH client to remotely access and control the RetroPie command line from your computer.

Naturally both your PC and Pi will need to be connected to the same network via Ethernet or Wifi in order to successfully transfer your files. On Mac OS X/macOS, open Finder, select "Go" menu and "Connect to Server". Type smb://retropie and hit "Connect".
