For the most part the remote play feature on the Vita has been working great, but there are some games that use the L3 and R3 buttons for important things and I dont know where to find these buttons on the Vita. The thumb sticks for the vita can’t be clicked so I am not sure how to get over this.
Assuming the game has no dedicated remote play support it will default to the standard button mapping that all remote play games on the Vita use. The L3 and R3 buttons can be found on the bottom left and right of the rear touch pad. The rear touch pad is split up into 4 sections. The top 2 are for L2 and R2. The bottom half is for L3 and R3
