Nintendo Badge Arcade

Nintendo Badge Arcade is an application that allows getting badges for the 3DS's Home Menu via a claw machine-like game.

SpotPass usage

The game can use four different URLs to retrieve game data.

• https://npdl.cdn.nintendowifi.net/p01/nsa/<regionID>/FGONLYT/playinfo_<gameVersion>.dat
• https://npdl.cdn.nintendowifi.net/p01/nsa/<regionID>/data/data_<gameVersion>.dat This file is a SARC archive with all game data (like machines and Miiverse posts) that is available within a period of one week. This data is updated every Friday at 1:40 AM GMT
• https://npdl.cdn.nintendowifi.net/p01/nsa/<regionID>/data/allbadge_<gameVersion>.dat This has a SARC archive with all game badges and machines for the game.
• https://npdl.cdn.nintendowifi.net/p01/nsa/<regionID>/news/<language>/news_<gameVersion>.dat

Where gameVersion goes the version of the game, which can be v130 or v131, langcode is the two-character language codes from config, and regionID is from the below table.

Region	ID
JPN	j0ITmVqVgfUxe0O9
USA	OvbmGLZ9senvgV3K
EUR	J6la9Kj8iqTvAPOq

RomFS

Inside the romfs data, we can find the following folders:

root
├── message
├── primitive_renderer
├── region_common
└── region_XXX

• "message" has all in-game dialogues
• "region_common" has a similar scheme to data.dat, but has all in-game assets
• "region_XXX" is similar as region_common, but has all region specific files, like the first badge machine. Where XXX goes the region name (EUR, JPN, USA)

    └─ XXxx
