Netplay grows up in NX Redux 2.1: play over a USB cable between two devices, link Game Boy Advance games with a real link cable, and start netplay straight from Home. Nintendo 64 now runs inside NX Redux's own emulator, PlayStation gains a second, sharper system (SwanStation) and Dreamcast a lighter one for the slower devices, and the menus run at a smooth 60 fps with more art choices for your game lists.

Select zip files that is relevant to your platform and extract it to your exFAT formatted SDCARD. Alternatively, you can update directly using the OTA update feature in the device.
Coming from v1.x? Back up your SD card before updating. A clean install is recommended: delete the hidden .system and .tmp_update folders from the card (keep Roms, Saves, Bios and .userdata, so your games, saves and settings stay), then extract this release as usual.
If you have any questions, please open an issue in the repository.
