[RPi4] 1 frame delay in menu and impossible controller mapping

Hello folks,

I'm running RetroPie 4.5.20 ( and DraStic on a Raspberry Pi 4 (2GB RAM model) with an SNES-like controller. I want to configure DraStic to my specific controller button, but the problem i'm facing is that i'm experiencing a 1-Frame-Delay in the menu (I got there by pressing M on a USB-Keyboard), so that any button press won't do anything until the next button press. This bug is also mentioned here: ... t-scroll/4.

I think this is also the reason why i can't configure DraStic to recognize my controller inputs correctly. I've found the drastic.cfg file but i don't know how to edit it correctly. Take - for example - this line of it:
controls_a[CONTROL_INDEX_UP] = 273
What exactly are the numbers right to the equal-signs? And how i can get the right numbers corresponding to my controller?
