Nintendo DSI Shop reverse-engineering notes

ECommerceInterface

This API provides access to information and features related to ecommerce. Such as providing a list of installed titles, etc

Setup

First it's necessary to create an instance of the ECommerceInterface class, the instance is used to interact with the API.

Nintendo create a single instance and store it globally as ec:

var ec = new ECommerceInterface();

Methods

getSessionValue(key)

setSessionValue(key, value)

getDeviceInfo()

Returns an object with

country
region
isParentalControlEnabled
userAge
language
accountId
deviceId
serial

getTitleInfos()

Returns a title list object containing details for every installed title. This function is slow, so it should only be called once and then be cached. The title list object can be iterated through like so:

var titleList = ec.getTitleInfos()
if (typeof(titleList) === "object") {
  // loop through title list
  for (i = 0; i < titleList.length; ++i) {
    // get title item by index
    var title = titleList.get(i);
    // get title ID
    var titleId = title.titleId;
    // etc
  }
}

DSi shop filters out some results from this. It will only show titles that follow some specific rules:

• The title ID must begin with 0001 (a Nintendo Partner ID) or 0003.
• The title ID cannot begin with 00010005; these are data titles.
• The title must have a personalised ticket; the deviceId value returned by getTicketInfos(titleId) cannot be 0.

getTicketInfos(titleId)

setWebSvcUrls(ecsUrl, iasUrl)

Set the SOAP endpoint urls for e-commerce and identity authentication.

In DSi Shop, ecsUrl = https://ecs.t.shop.nintendowifi.net/ecs/services/ECommerceSOAP and iasUrl = https://ias.t.shop.nintendowifi.net/ias/services/IdentityAuthenticationSOAP

setContentUrls(ccsUrl, ucsUrl)

In DSi Shop, ccsUrl = http://ccs.cdn.t.shop.nintendowifi.net/ccs/download and ucsUrl = https://ccs.t.shop.nintendowifi.net/ccs/download

getProgress()

cancelOperation()

checkDeviceStatus()

refreshCachedBalance()

checkParentalControlPassword(password)

getWeakToken()

getDeviceInfo()

Returns object with:

• country
• region
• isParentalControlEnabled
• userAge
• language
• accountId
• deviceId
• serial

ECTimeout

Unsure what this timeout does exactly, its constructor takes an integer value eg var timeout = new ECTimeout(60000)

Kong API

DSi Shop also provides a general JavaScript interface via the Kong API, this API includes things such as page transitions, playing sound effects, detecting button input and some other neat features.

First it's necessary to create an instance of the Kong constructor (a reference to Donkey Kong, I suppose?), the instance is used to interact with the API.

Nintendo create a single instance and store it globally as gkong (probably short for "global kong"), so we'll be doing the same:

var gkong = new Kong;

Now the following methods will be available on gkong:
