Xenia emulator

I wanted to use the Xenia emulator here, just the hardware allows and it seems like you can use the keyboard there.
but I ran into such a problem that some functions are not clear what they are assigned to - what are the values ​​u200bu200bof "0xb" - is it possible to somehow reassign them?

the control section looks like this:
Spoiler[HID.WinKey]
keybind_a = "0xBA" # List of keys to bind to A, separated by spaces
keybind_b = "0xDE" # List of keys to bind to B, separated by spaces
keybind_back = " Z" # List of keys to bind to BACK, separated by spaces
keybind_dpad_down = "^S" # List of keys to bind to DPAD_DOWN, separated by spaces
keybind_dpad_left = "^A" # List of keys to bind to DPAD_LEFT, separated by spaces
keybind_dpad_right = "^D" # List of keys to bind to DPAD_RIGHT, separated by spaces
keybind_dpad_up = "^W" # List of keys to bind to DPAD_UP, separated by spaces
keybind_left_shoulder = "1" # List of keys to bind to LEFT_SHOULDER, separated by spaces
keybind_left_thumb = "F" # List of keys to bind to LEFT_THUMB_PRESSED, separated by spaces
keybind_left_thumb_down = "_S" # List of keys to bind to LEFT_THUMB_DOWN, separated by spaces
keybind_left_thumb_left = "_A" # List of keys to bind to LEFT_THUMB_LEFT , separated by spaces
keybind_left_thumb_right = "_D" # List of keys to bind to LEFT_THUMB_RIGHT, separated by spaces
keybind_left_thumb_up = "_W" # List of keys to bind to LEFT_THUMB_UP,separated by spaces
keybind_left_trigger = "Q I" # List of keys to bind to LEFT_TRIGGER, separated by spaces
keybind_right_shoulder = "3" # List of keys to bind to RIGHT_SHOULDER, separated by spaces
keybind_right_thumb = "K" # List of keys to bind to RIGHT_THUMB_PRESSED, separated by spaces
keybind_right_thumb_down = "0x28" # List of keys to bind to RIGHT_THUMB_DOWN, separated by spaces
keybind_right_thumb_left = "0x25" # List of keys to bind to RIGHT_THUMB_LEFT, separated by spaces
keybind_right_thumb_right = "0x27" # List of keys to bind to RIGHT_THUMB_RIGHT, separated by spaces
keybind_right_thumb_up = "0x26" # List of keys to bind to RIGHT_THUMB_UP, separated by spaces
keybind_right_trigger = "E O"# List of keys to bind to RIGHT_TRIGGER, separated by spaces
keybind_start = "X" # List of keys to bind to START, separated by spaces
keybind_x = "L" # List of keys to bind to X, separated by spaces
keybind_y = "P"
