João13 is a Brazilian website dedicated to video game translations and dubbings, bringing community-created language projects together in an organized, searchable catalog. Its collection spans a wide range of platforms, from classic systems such as the NES, Super Nintendo, PlayStation, and Mega Drive to newer consoles, PC, mobile devices, and other gaming hardware. Visitors can browse projects by platform and explore separate sections for translated games and dubbed releases, with listings that identify versions and, where provided, the creators or contributing groups.

Beyond its main catalog, João13 publishes gaming news covering consoles, computers, mobile games, hardware, films, and series. The site also offers practical resources for users interested in modifying or working with game files, including tools for creating and applying patches, converting data, creating images, inserting or extracting data, and handling video playback. Tutorials and save files are available as well. With links to social channels, community spaces, donations, and partner sites, João13 serves both players looking for Portuguese-language game projects and enthusiasts seeking related resources.
