What controllers are required?

For PS4 games, you need a standard DualShock.

For PS5 games, this can't be done with the Keymander 2 standalone anymore since Sony started requiring DualSense controllers for PS5 games along with a periodic authentication check.

To play any PS5 game on a PS5 console, you will require a method of getting around the consoles DualSense authentication check.

There are a few different ways of doing this such as:

Remote Play via an adapters such as the Beloader series:

Remote Play via a PC:

Besavior Series:

Besavior U5 (beloader.com)

Please note that these methods are all subjected to some latency which can vary in setups. In my opinion (along with a few others), believe that the Besavior U5 seems to be the best as for latency.
