NX-NONET Switch

NX-NONET is a SaltyNX plugin that fake no available internet connection to avoid nag on some games without enabling airplane mode.

You need masagrator SaltyNX fork installed.

Installation

To install, put NX-NONET.elf to /SaltySD/plugins/.

This plugin hooks the nn::nifm::IsNetworkAvailable() function and always returns 0, telling the games no network is available.

Also available are these alternate SaltyNX patch versions (they are the same, but may work better than the plugin):

IsNetworkAvailableEv.asm64 by bestpig - Compatible with 64-bit games. (2022/04/04)
SaltySD-Nop-Network by bestpig - This version also eliminates the nag (e.g. "could not connect", "turn off airplane mode"). (2022/06/01)
_ZN2nn4nifm20SubmitNetworkRequestEv.asm64 by mrdude - This patch bypass the error "Notice - Loading Title Storage" when loading with the internet turned on (airplane mode off) and network is unreachable. (2023/09/16) Requires the following files from SaltySD-Nop-Network.zip:
- _ZN2nn4nifm31HandleNetworkRequestErrorResultEv.asm64
- _ZN2nn4nifm18IsNetworkAvailableEv.asm64

To use the patches, place them into /SaltySD/patches/.
