Nintendo Switch Emulator with NeXo Network Online Support

---

What is NeXoEmu?

NeXoEmu is a Nintendo Switch emulator based on Eden with full NeXoNetwork online services integration. It allows you to play Nintendo Switch games on PC with online multiplayer support through Raptor Network's infrastructure.

• Base: Eden Emulator (2026, actively maintained fork of yuzu)
• Online layer: Ported from RaptorCitrus (Raptor Network client, 2021)
• Project: NexoEmu — a modern, online-capable Nintendo Switch emulator
