Is there any way to get rid of the USA at the end of each of them If you're using a mac, download Unarchiver instead of 7zip. But that is all optional and definitely not required if you arent interested in customization. And if you eventually get into customizing how your retropie loads & looks, some other downloads may be required. Some disc consoles and arcade emulators require a BIOS file be downloaded and added before playing (pretty much same process as adding a game rom - just DL the correct BIOS file and transfer it into the Retropie's BIOS folder instead of the ROMS folder as you would for the games). Other than these, the only other downloads required for ' most' of the emulators are your game roms (most of atari through SNES/Genesis generations are good to go with just adding the roms to the correct emulator). These are the only three downloads required for basic setup. 7Zip: more than likely you'll need the 64 bit version WIN32DiskImager - from SourceForge website: it should ask you if you want a short cut on your desktop.
Everyone who is starting to build one - here are the downloads with links: Retropie - DL the version for pi 2/3 if you bought a 3: remember where you save this DL.
