nwc24.getFriendNum()
Returns the amount of friends on the user's friends list.
nwc24.getFriendInfo(num, type)
Queries information about the given friend list entry at num. For all possible type values, see Friends List.
nwc24.sendGiftMailAsync(friendIndex, urlPath, message, miiIndex)
Sends a mail using the gift design template with a body of the given message. The recipient is specified by friendIndex from the friends list. The sending user adds their Mii via miiIndex. urlPath is the URL this channel opens to when the Start button is clicked. Please see Async Handling for more information about the workflow for handling mail errors.
nwc24.sendReturnMailAsync(friendIndex, message, miiIndex)
Similar to the above, however lacking the url parameter. The gift return design template is used.
nwc24.sendNormalMailAsync(friendIndex, message, miiIndex)
Similar to the above. As the name implies, no mail design template is applied.
nwc24.isBusy()
Returns whether the internal mail engine is currently processing an operation.
nwc24.dispError(code, type)
Displays an error with code. There are 3 available types, though they appear ambiguous:
  • No type (or no arguments) displays an error screen with "Wii Menu" and "Reset Channel".
  • Type 2 appears to have a "Wii Menu" and "Reset Channel" button, though sometimes it does not.
  • Type 8 appears to only show "Reset Channel".
nwc24.doLeftBtn()
Handles function for the button displayed on the left within errors. Depending on the error type, the button either effectively goes to the last loaded page in history, or it resets the channel.
nwc24.doRightBtn()
Called whenever the button on the right within error pages is selected. Depending on the error type, it either loads the initially loaded URL (for example, /startup) or resets the channel.

nwc24.leftBtn nwc24.rightBtn
Returns a localized string to be displayed on the button within the given side of the page. The button's string is determined from several factors. For the right button:
  • Is there a pending NWC24 error?
    • If so, and the error is of type 4 or 10, the error is the localization of "Reset".
    • Otherwise, the string is the localization of "OK".
For the left button:
  • Is there a pending NWC24 error?
    • If so, and the current error minus seven (?) is greater than 2, or the current error is 10, localize "Try Again".
  • What is the current launch code for the channel?
    • If the launch code is 2 or 8, localize "Back".
    • Otherwise, localize "Wii Menu".
