Sony has closed a back door into the Chinese version of its PlayStation Store, ensuring that only games officially released in the region can be downloaded through its marketplace.
The South China Morning Post reports the exploit was disabled by a new system update this week.
Prior to the update, owners of the mainland China model of PlayStation 4 could hold down specific buttons while resetting the machine to gain access to other versions of the Store. This enabled them to buy and download titles that had yet to be approved by Chinese regulators.
