Assuming you have a hacked Switch running Atmosphere or SX OS (legacy), here is how to apply the new LA Noire NSP update:
As of late 2025, LA Noire on the Switch has reached its final stable state. Rockstar has not released a major patch for the game since 2018, but a few crucial updates were rolled out post-launch. If you are searching for a new update, you are likely looking for the Title Update v1.2 (or v1.3 depending on regional release) , which includes: la noire switch nsp update new
The latest update file (often labeled [010044200A6C0800][v0] – though the v number varies) typically clocks in at 1.2 GB to 1.5 GB. You will rarely see a “new” update beyond this, as the game is considered legacy software. Assuming you have a hacked Switch running Atmosphere
