@rbaker said in 2 player start button?:

What is in your retroarch.cfg file regarding player two controls? Did you add them?

Please answer this ^^^^^^^^^^ the file is located at /opt/retropie/configs/all/retroarch.cfg

do you see entires that reference player two?

input_player2_a = "x" input_player2_b = "z" input_player2_y = "a" input_player2_x = "s" input_player2_start = "enter" input_player2_select = "rshift" input_player2_l = "q" input_player2_r = "w" input_player2_left = "left" input_player2_right = "right" input_player2_up = "up" input_player2_down = "down"

Have you read this with regard to /opt/retropie/configs/all/retroarch-joypads

nor does it offer a solution

It offered possible explanation......."Reading around the inter webs, it seems that that brand of joystick has general issues in Linux of all flavors. It may be that there is no good solution other than getting a tried and tested controller that is known to work well"
