# headless -- Controls the boot mode config of openMSX from environment variables.
|
|
#
|
|
# Typically used in automation tools which run openMSX without human interaction.
|
|
#
|
|
# Adds the following command to openMSX;
|
|
#
|
|
# 'headless_exit'
|
|
# A normal exit of the openMSX emulator.
|
|
#
|
|
# 'headless_show_gui'
|
|
# Enables the renderer and throttle from the inside.
|
|
#
|
|
# Supported environment variables by this script;
|
|
#
|
|
# HEADLESS=on|off
|
|
# Override video output from command line.
|
|
#
|
|
# RENDERER=SDL
|
|
# Select video renderer type for GUI mode or in none headless mode.
|
|
#
|
|
# SCALE_FACTOR=3
|
|
# Override video scale factor for the renderer.
|
|
#
|
|
# THROTTLE=off
|
|
# Disables MSX speed emulation.
|
|
#
|
|
# SPEED=333
|
|
# Sets CPU speed to relative from normal but only when throttle is on.
