Can I use hotkeys for R2 and L2 buttons, using SNES controller on PSX?

Now that I have my Raspberry Pi set up to play the games I want, I thought I’d learn how to set up the other emulators as well. Since I already bought SNES controllers, and they don’t have the R2 and L2 buttons that PSX would use, that leaves me with a problem.

I’m interested in how hotkeys work, though. I use hotkeys already for system functions. I’ve set up my retroarch.cfg file with these commands, which work perfectly:

input_enable_hotkey_btn = 8 input_exit_emulator_btn = 9

input_enable_hotkey_btn = 8 input_save_state_btn = 4

input_enable_hotkey_btn = 8 input_load_state_btn = 5

But when I try the same thing with a gameplay function (I’ve been testing it with the A button, for simplicity):

input_enable_hotkey_btn = 8 input_player1_a_btn = 1

Retroarch doesn’t bind the button to the hotkey command before it. It just reads it as though it were a normal gameplay command, listed above with all the rest.

Is it possible to use hotkeys for gameplay inputs? If so, which files would I have to alter, and how should I do it?

Thank you for your help.
