# There is no need to uncomment it unless you are either using a CDTV, you want
# to use a physical RTC source present inside the computer, such as on a trapdoor
# memory expansion board, or if you have a physical A314 intalled, since the
# A314 uses the RTC address range to communicate with the Amiga, and enabling RTC
# emulation blocks this communication completely.

# Please take note:
# At the time of writing this (22 Jun 2021), the mouse and keyboard forwarding
# (for Amiga only) is by no means perfect. It works properly in Workbench, and
# in a number of games and applications, but it does not work for everything.
# Do not rely on the mouse and keyboard forwarding as your only means of input
# for the host computer.

# Forward keyboard events to host system, defaults to off unless toggle key is
# pressed, toggled off using F12.
# Syntax: keyboard [grab key] [grab|nograb] [autoconnect|noautoconnect]
#   "grab" steals the keyboard from the Pi so Amiga/etc. input is not sent to
#   the Pi (also helps prevent sending any ctrl-alt-del to the Amiga from
#   resetting the Pi)
#
#   "autoconnect" connects the keyboard to the Amiga/etc. on startup
#keyboard k nograb noautoconnect
# Select a specific filename for the keyboard event source.
# This is typically /dev/input/event1 or event0, but it may be event3 with for
# instance a wireless keyboard.
# Use ls /dev/input/event* to check which event files are available and try
# until you find the one that works.
#kbfile /dev/input/event1
# Forward mouse events to host system, defaults to off unless toggle key is
