PS4 Title Update Information

This package retrieves information about the latest update available for a PS4 title. The information is stored in a Ps4TitleUpdate object which you can integrate into your Python application. Alternatively it can print this information directly to the screen (for use in a simple CLI application), and it can save the retrieved information as files. This package does not download entire PS4 title update files.

Installation

pip install ps4-updates

Typical Usage

Create a Ps4TitleUpdate object by specifying a PS4 Title Id (eg. CUSA00001_00 or CUSA00001).

Invoke get_update() on the object to begin retrieving information about the update. If an update is available it will try to retrieve the following:

• Title Name
• Update Url
• Current Version
• Content Id
• Download Size
• Update Creation Date
• changeinfo.xml (developer included update notes)

Limitations

Only information about the current update version can be retrieved.

It is not a guarantee that changeinfo.xml will be included within the updates pkg file. The file is typically located at the start of the file, however it does not appear to be in a fixed location. This package attempts to locate it by downloading up to the first 30MB of the pkg file. You can increase (or decrease) this search range by setting byte_limit when creating a Ps4TitleUpdate object.

Usage Examples

Create Ps4TitleUpdate object and retrieve update information

from ps4_updates import title as ps4up

title = ps4up.Ps4TitleUpdate('CUSA00001')
title.get_update()

See object attributes reference.

Create Ps4TitleUpdate object, retrieve update information, and output to the screen

from ps4_updates import title as ps4up

title = ps4up.Ps4TitleUpdate('CUSA00001')
title.get_update()
title.print_update_info()
