Dreamcast "Escape" Button

[Concat]

I have done some custom mapping for Reicast, and all seems to be working well apart from exiting the emulator. Right now I have to use cntrl-c to exit.

Reading the wiki helped a lot, but I am quite confused by the different formats of the example config files. Under Controls , there is an example config for PS3 controller. https://github.com/retropie/retropie-setup/wiki/Dreamcast

[PLAYSTATION(R)3 Controller]
button.0=Btn_Z
button.1=Btn_C
button.2=Btn_D
button.3=Btn_Start
button.4=DPad_Up
button.5=DPad_Right
button.6=DPad_Down
button.7=DPad_Left
button.8=Axis_LT
button.9=Axis_RT
button.10=DPad2_Left
button.11=DPad2_Right
button.12=Btn_Y
button.13=Btn_B
button.14=Btn_A
button.15=Btn_X
button.16=Quit
axis.0=Axis_X
axis.1=Axis_Y

Note in this file it says button.16=Quit

Further down it has this config file:

[emulator]
mapping_name = Xbox Gamepad (userspace driver)
btn_escape = 0x13a

[dreamcast]
btn_a = 0x130h
btn_b = 0x131h
btn_c = 
btn_d = 0x139h
btn_x = 0x133h
btn_y = 0x134h
btn_z = 0x138h
btn_start = 0x13Bh
axis_x = 0x00
axis_y = 0x01
axis_trigger_left = 0x0a
axis_trigger_right = 0x09

[compat]
axis_dpad1_x = 0x10
axis_dpad1_y = 0x11

Here is has btn_escape = 0x13a instead of Quit, and the ordering is flipped. That is, mapped button = controller input vs controller input = mapped button. Perhaps the ordering doesn't matter... but what is Quit vs btn_escape?

@Concat
The 2nd one is closer to the correct format but not sure about the button mapping.

Just run evtest to get the correct mapping.
