The Nintendo 3DS eShop was added in the June 2011 update for JP/EUR/USA.

From here, you can download Virtual Console games, 3D Classics, DSiware software, view screenshots, and 3D trailers for upcoming 3DS titles.

While eShop is loading, eShop will use command NIMS:CheckSysupdateAvailableSOAP. If a system update is available where title installation for system titles still needs finalized (or when the updated titles were not downloaded at all), eShop will then display the "system update is available" message.

The eShop application uses command AMNet:FinishInstallToMedia to finalize the SD title install (if the whole title is downloaded while eShop is still running), however, before using that command the eShop application also uses AMNet:FinishInstallToMedia to finalize installing all system titles (from system updates).

eShop QR Codes

eShop QR Codes can be scanned with the camera, allowing one to quickly navigate to the desired eShop title with just two clicks. The QR Codes themselves is a simple text/url QR, started with "ESHOP://" string followed by a decimal eShop content link id(same IDs used internally by eShop for all content) and then some special data, delimited by a dot symbol, which can be ommited.

In order for the QR-code string data to be valid for eShop, it must begin with "ESHOP://5", with the first ID being all decimal.

  • New QR Code for Japanese "Photos with Super Mario" has a different code string: ESHOP://50010000013120.J00108Z00001.CD588EAE95A3A68D15C647DA2AC0945FD88F70AB8A31149E51C4B05FB927B0B8
  • There is a link in the Japanese eShop [http://www.nintendo.co.jp/3ds/eshop/qrCode.html?####] where you can replace the #### with the Japanese eShop title's serial and you will get it's QR code. (i.e. http://www.nintendo.co.jp/3ds/eshop/qrCode.html?jcaj will get you the pushmo QR code)

NS eShop application parameters

This section describes the 0x1C-byte structure stored at the application parameters from APT:StartApplication, under the 0x300-byte buffer listed there.

Offset Size Description
0x0 0x4 Unknown, usually 0x3?
0x4 0x4 Unknown, usually 0x0?
0x8 0x8 u64 binary eShop content ID, same ID from the first string in eShop QR-codes except in binary form.
0x10 0x10 This is the last string from the QR-code(if any), no NUL-termination.

ExtData

The ExtData File System for eShop is as follows: 

root
├── icon
├── boss
│   └── TIGER100.tmp
└── user
File Details Size Firmware Introduced Plain text
icon Duplicate from application ExeFS. Always image 00000002 0x36C0 Bytes 2.0.0-2 Download_EUR
TIGER100.tmp Always image 00000003. 0xCE47 bytes (varies?) 2.0.0-2

Music

The eShop pulls its music from a static, region-specific link in a format similar to the following:

https:// a248.e.akamai.net/f/248/103046/10m/npdl.c.app.nintendowifi.net/p01/nsa/CtfKXACbUPl8s7lk/BGM1/US_BGM1 , where region is one of the primary system regions (JP, US, EU, KR, etc.) Support also exists for 'BGM2', but this seems to be unused. The music is held in a BOSS container.

The format consists of a brief XML header describing the audio (including the date it was set as the main eShop theme, loop times, size, etc) followed by a raw AAC stream. Tools such as FFmpeg can handle rebuilding this stream with ADTS headers for proper time info and such.

The Home Menu uses nearly the same format for the Theme Shop's background music.

URLs

eShop uses the following domains over HTTPS:

  • cp3s-auth.c.shop.nintendowifi.net
  • a248.e.akamai.net
  • ninja.ctr.shop.nintendo.net
  • samurai.ctr.shop.nintendo.net
  • ccif.ctr.shop.nintendo.net
  • eou.c.shop.nintendowifi.net

These domains are used by NIM:

  • nus.c.shop.nintendowifi.net
  • ecs.c.shop.nintendowifi.net
  • cas.c.shop.nintendowifi.net

ninja.ctr.shop.nintendo.net and samurai.ctr.shop.nintendo.net contain the bulk of the eShop information.

Common Parameters to ninja and samurai

For every request to the ninja and samurai servers, three parameters are always sent, though are not necessarily required:

Parameter Required Description Type Normal value
shop_id depends on the URL, usually no Describes which eShop instance should be used. 1 indicates the 3DS eShop, 2 indicates the Wii U eShop. 3 seems to yield the same results as 2. Values greater than 3 or less than 1 are invalid. Defaults to 2 or 3 if not given. unsigned integer 1
lang no Describes the language. Seems to be an ISO 639-1 code in lower case. Every eShop region has a default language that is used if this parameter is not given. Some regions have multiple languages, such as CA (en and fr). string (two characters) depends on region and eShop settings; for US: en
_type no Describes whether the client wants to receive JSON or XML. This parameter seems actually unused and the servers always return XML. string json

samurai

samurai.ctr.shop.nintendo.net (samurai) provides metadata about titles. The samurai server provides the backend for the eShop title search.

Common parameters described above can always be sent.

Path Description Parameters
/samurai/ws/region/titles Fetches the title list, containing the content id (not the 3DS title id), the product code and the localized title name All of these are optional.
  • genre[]: genre ID (unsigned int)
  • publisher[]: publisher ID (unsigned int)
  • price_min: minimum price in region currency (signed int)
  • price_max: maximum price in region currency (signed int)

  • freeword: keyword(s?) to look for (string)
  • limit: maximum results
  • offset: results to skip
  • sort: one of "new", "popular" or "score"
  • release_date_before: date/time title must have been released before (UNIX timestamp prefixed by +)

Path Description Parameters
/ninja/ws/region/title/content id/ec_info Contains information about the title. Such as title id, content size, and if available, the 9.6 crypto seed (none)
/ninja/ws/titles/id_pair Provides the content id for the given title id, or vice versa. title_id[] or ns_uid[] is required.

Trusted Root CAs

The eShop application itself uses a RootCertChain for all HTTPS requests, all of the trusted root CAs are the following default ones:

  • CertID 0x3
  • CertID 0x6
  • CertID 0x7
  • CertID 0x8
  • CertID 0x9
  • CertID 0xA

Server changes following the November 2, 2015, maintenance

Pre-v10.0 eShop used an URL like this: "%s/samurai/ws/%s/title/%llu/other_purchased?shop_id=1&lang=%s&_type=json". That URL was removed with v10.0. That URL was requested when trying to load eShop app-pages. Following the maintenance mentioned above, this page was removed from the server, which broke pre-v10.0 eShop app whenever it tried to access that page.

URL changes between 9.7.0-25 and 10.0.0-27 are (green = add, red = remove):

%s/ninja/ws/%s/titles/online_prices?title%%5B%%5D=%s&lang=%s&include_coupon=true&shop_id=1&_type=json

New3DS

CheckNew3DS is called in two functions. This is only used for disabling UI button(s) for downloading New3DS titles when running on Old3DS. For example, on a New3DS patching a CheckNew3DS func-call with <retval=0>, results in the download button on the app page being grayed-out for a New3DS-only title.

TitleID checks

There's titleID checks in the system eShop application code for "Pokémon Omega Ruby". This appears to be used with UI-related code, unknown why.
