Welcome to the Emulationstation-OGA-Theme-Gallery wiki!

Here, I'll try to answer as many frequently asked questions about themes on OGA and its clones.

How to download and add theme

You can download a theme from github by hitting the green button Code > Download Zip

Unzip contents into your distributions theme folder. Not all folders are the same between OS distributions. For example you can access ArkOS theme folder on the EASYROMS partition themes\ folder.

You can also download themes using Theme Master by JohnIrivine1433 (if using ArkOS or TheRA). 351elec also has a theme downloader built into emulationstation.

Missing Systems

You can add systems by following the themes folder structure. Most themes either have their system images in the root folder as sperate system folders. Some themes have system images in inside folders called _art\, art\, inc\, or _inc\. Check the file format and image sizes of other images you find and follow them. There's no standard so double check with the root theme.xml if your confused.

• If you've installed a theme and it looks like this

Make sure you've placed the theme correctly in the theme folder

Folder Structure
themes\themename\theme.xml	Right
theme\themename\themename\theme.xml	Wrong

• Every distribution is not 1/1 so you might need to change a few image and system folders names around to match that of your OS distribution. For instance ArkOS uses pokemonmini while TheRA\351elec use pokemini

Theme doesn't fit screen

Every theme in the readme should give you what each screen size is supported. Some themes either separate screen sizes as entirely different themes, must be switched using theme configurations options, or don't need any modification between screen sizes. Items still might not fit, if so you can try contacting the author and explain your issue with them.

Theme Configuration

You can change theme configurations by:

Entering Emulationstation Menu (Start Button ) > UI Settings > Theme Configuration >

You can change many options in the Theme Configurations such as: theme color, screen size, images, and other fantastic options. Not every theme has configurations and must be added by the author.

Creating themes

Creating themes is an involved process. But don't be discouraged its not hard! You can check these guides:
