Generic PS3 controllers act like keyboards

[G2bb]

Yesterday I received 2 generic off brand PS3 controllers. I was finally able to get them to pair this morning, however, they are being detected as keyboards and as such not all of the functions of the controller are available to use. The joysticks do absolutely nothing and most of the buttons just map to some random key on a keyboard. I am hoping that there is a way to configure them to act as controllers instead of a keyboard. Any help would be awesome!

EDIT
Since some of the buttons work I tried going into RetroArch setup to configure what controls I could, however when I get in it tells me that the controller isn't compatible and won't take any input from any device including my actual keyboard.

While there are a few good ways to make a standard controller be seen as a keyboard, I don't know of anything that would do the reverse. There's a proposed way to do it with xboxdrv, but the project hasn't been touched since late 2015. However, seeing as how all these emulators and ports are first and foremost computer software, they all have keyboard support that can even be a bit more versatile in many cases.

Using RetroArch as a jumping off point, if you can determine which keys are assigned to which buttons, the controls can be added manually to /opt/retropie/configs/all/retroarch.cfg. Below is an example of my setup that you can use as a reference.

input_player1_a = "a"
input_player1_b = "b"
input_player1_y = "y"
input_player1_x = "x"
input_player1_start = "t"
input_player1_select = "e"
input_player1_l = "l"
input_player1_r = "r"
input_player1_left = "left"
input_player1_right = "right"
input_player1_up = "up"
input_player1_down = "down"
input_player1_l2 = "d"
input_player1_r2 = "f"
input_player1_l3 = "c"
input_player1_r3 = "v"

input_player2_a = "k"
input_player2_b = "m"
input_player2_y = "o"
input_player2_x = "n"
input_player2_start = "num9"
input_player2_select = "num0"
input_player2_l = "p"
input_player2_r = "q"
input_player2_left = "g"
input_player2_right = "h"
input_player2_up = "i"
input_player2_down = "j"
input_player2_l2 = "s"
input_player2_r2 = "u"
input_player2_l3 = "w"
input_player2_r3 = "z"
