New Feature - Boxcat
Written by CaptV0rt3x on May 23 2019

Good day, yuzu fans! Today we bring you another exciting Switch feature which will create opportunities, for new in-game content across various games! Without further ado, let’s get started!


Yes, you heard that correctly. New in-game content across various games, with events held occasionally.


The Nintendo Switch has a network service called BCAT, using which games can add new content dynamically, i.e. new content without updating the game itself. Nintendo can push new content to various games via this service, whenever it wants. Some examples of this type of content would be - Super Mario Odyssey hints, Super Mario Odyssey costumes, and Splatoon 2 items.


Users should possess the following versions of the games at minimum.
SMO - 1.2.0 || BOTW - 1.1.0 || Splatoon 2 - 3.2.0


The Legend of Zelda - Breath of The Wild, now boots with updates and DLC enabled.


Thanks to the efforts of our developer DarkLordZach, we now have an open source replacement of the service in yuzu. By emulating the BCAT service at a high-level, yuzu is able to intercept the game’s calls to Nintendo’s servers and reroute them to yuzu’s servers. This means that games running on yuzu, will now check for new content on yuzu’s servers instead of Nintendo’s.

This allows us to add new in-game content for games that use this service. For the inaugural run, our team members have added some cool content across different games which you can check out here. We will have new events occasionally, so users will have even more fun while playing games on yuzu.
