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	?
USA	OvbmGLZ9senvgV3K

RomFS

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

root
├── message

└── 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)

ExtData

Inside the extdata, we can find the following files:

• "addSaveData"
• "allbadge.sarc" A register of all badges retrieved from data_<gameVersion>.dat file?
• "boss.sarc" The data_<gameVersion>.dat file retrieved from SpotPass
• "savedata"
