Mayflash MAGIC-NS

Been testing this setup of an Xbox One controller connected to a MAGIC-NS adapter from Mayflash for a few weeks already and it allows me to natively map the RT/LT buttons in PSOBB and PSU without the need of any kind of mapping software. It also allows PSOBB to see the Xbox controller as a truly DINPUT Device and allowing the sticks to act as buttons and thus allowing you to unfreeze yourself with the Stick just like in the Gamecube with PSOGC.

A more elegant solution you can consider to standardize all your controllers to play old games more comfortably.
