Updatelist.xml

PS5 checks for updates by sending a GET request to fus01.ps5.update.playstation.net/update/ps5/official/tJMRE80IbXnE9YuG0jzTXgKEjIMoabr6/list/us/updatelist.xml where 'us' is your consoles region, parsing it to find download links to *.PUP files.

The format of 'updatelist.xml' is the same as 'ps4-updatelist.xml' from PS4 and 'psp2-updatelist.xml' from PSVita. The only differences now are that it's not called ps5-updatelist.xml but rather just 'updatelist.xml' and that Sony added a random string into the URL after the 'official'-folder.

Example updatelist.xml ('us'-region)

<?xml version="1.0" ?>
<update_data_list>
	<region id="us">
