Nextendo v1.7.8

Nextendo v1.7.8 is released. Nextendo is a fork of the open-source Ryujinx Nintendo Switch emulator. On top of Ryujinx's excellent accuracy and performance, Nextendo adds a first-class, built-in client for the Nextendo Network — a community-run replacement for the official online service — so supported games can be played online again without any manual configuration, custom hosts file, or SSL bypass on the user's part. The emulation core (CPU, GPU, audio, input, filesystem) is unchanged from upstream Ryujinx. Nextendo's additions are limited to the networking layer and the surrounding user experience.

Nextendo Changelog:
Nintendo shipped Splatoon 3 11.3.0, and Nextendo now runs on it.
This is a mandatory update. Online play needs everyone on the same game build — two different builds in one lobby desynchronise each other, so only one version is supported at a time. From this release, that version is 11.3.0.
What you need to do: update Splatoon 3 to 11.3.0, and update Nextendo to 1.7.8. If your game is still on 11.2.0, Nextendo tells you so before launch instead of letting you hit a connection error with no explanation.
The certificate patches ship inside the emulator, as before — there is no file to install, no patch folder to manage. Both 11.2.0 and 11.3.0 patch sites sit at the same offsets, verified by comparing the decompressed program images of the two versions.
