Notes About Setting up RetroPie

Setting up RetroPie on a Raspberry Pi is fairly easy but I did come up against a couple of issues that I needed to fix. This post is just a collection of quick fixes for those issues.

Remove underscored games when transferring from a Mac

When copying ROMs from a Mac, you may end up with a bunch of files that start with an underscore. To remove them all, run the following:

1
find /home/pi/RetroPie -name "._*" -exec rm -rf {} \;

Finding Installed Themes

For the theme I’m using, I wanted to edit the SNES background image to use the non-US SNES (read: the one true SNES). Installed themes are stored in /etc/emulationstation/themes.

Finding decent ROMs

The best site I’ve found for searching for specific ROMs is Complete ROMS. They don’t have everything but the site is clean and easy to find exactly what you’re looking for.
