As you probably already know, the G25´s shifter is extremely functional as it can be configured as an h-pattern shifter or a sequential shifter.
What maybe you don´t know yet is that you can push the shifter down when h-pattern mode is selected. "Pushing down and setting a gear", will result in a different button than just "setting that gear".
This feature allows you to simulate, for example, a 6-gear car gearbox, configuring the reverse in the push-and-first_gear or push_and_sixth gear, just like in many real cars.
The G25 is fantastic !
