# Run the instruction fuzzer (requires validator feature)

# Do aspect correction to convert display buffer to 4:3.  May introduce some
# resampling blur. This can be toggled on/off in options menu.

# Debug mode does a few miscellaneous things. 
# - CPU Autostart is disabled
# - Several debug panels are opened automatically
# - CPU Instruction history is turned on (overrides setting)
debug_mode = false

# Warn if MartyPC was compiled in debug mode. Disable this if you intended to
# do so and don't want the nag.  Unfortunately, 'cargo build' makes a debug 
# build by default...
debug_warn = true

# Don't load BIOS if true (not useful on its own)

# be set to 'run_bin_seg:run_bin_ofs'

# Debug Tracing Options
# ----------------------------------------------------------------------------
# CPU tracing may be enabled by specifying trace_mode
# Tracing does not begin unless trace_on == true or set in GUI
#
# Valid values for trace_mode:
# "Instruction" -> Perform per-instruction traces (slow, big)
# "Cycle" -> Perform per-cycle traces (slowest, biggest)
#  >>> WARNING: This will quickly make multi-gigabyte files.
#
# Additionally, a valid value for trace_file must be supplied.
#
trace_on = false
trace_mode = "Cycle"
#trace_file = "./traces/instr_trace.log"

# Enable Video tracing. Video device may log memory and register read/writes.
#video_trace_file = "./traces/video_trace.log"

# Enable Video frame debugging. This will display the entire video field 
# including overscan and blanking periods for cards that support Direct 
# rendering (CGA only for now)
video_frame_debug = false

# Enable PIT output save to file.  All samples from PIT will be saved to disk.
#  >>> WARNING: This will quickly make multi-gigabyte files.
#pit_output_file = "./traces/pit_output.pcm"
# Use emulator service interrupt to trigger PIT output writing
#pit_output_int_trigger = true 

[gui]
# ----------------------------------------------------------------------------
# GUI options
# ----------------------------------------------------------------------------

# Disable the GUI entirely. Use autostart=true or you'll have no way to start
# the machine.
gui_disabled = false 

# Specify the base color for GUI control theme. Ideally use something dark and 
# desaturated. Comment out for default EGUI theme.

[cpu]
# ----------------------------------------------------------------------------
# Various CPU related options.
# ----------------------------------------------------------------------------

# Enable CPU wait states. This includes wait states from DMA, memory access
# and device IO. Setting this to false may speed up the CPU, but reduce 
# accuracy (Area 5150 will break)
wait_states_enabled = true

# Attempt to detect when the CPU is executing invalid instructions and halt.
# May need to disable for certain test programs like acid88
off_rails_detection = false

# Whether to enable instruction history by default. This slows down the 
# emulator a modest amount when enabled.

[input]
# ----------------------------------------------------------------------------

# Some platforms reverse the left and right mouse button id #'s. 
# We try to detect this, but it can be overridden here.

[machine]
# Machine info
# ----------------------------------------------------------------------------

# "IBM_XT_5160"

# ROM Override
# ----------------------------------------------------------------------------
# Specify a specific BIOS to load. This overrides MartyPC's ROM autodetection.

# This feature is intended for advanced users. The address will depend on the
# ROM loaded. Please indicate if you are using this feature if you need to
# report issues.

# Values for 'org' include
#    Normal,
#    Reversed,
#    InterleavedEven,
#    InterleavedOdd

# Used by web player. Do not modify.
raw_rom = false

# Turbo Button
# ----------------------------------------------------------------------------
# Change the clock divisor/multiplier for the CPU to run the CPU faster than 
# normal. Other devices like the timer will continue to run at the same rate.
#
# On IBM PC/XT, turbo increases CPU clock from 4.77Mhz to 7.16Mhz.
turbo = true

# Video card type.
# ----------------------------------------------------------------------------
# Valid options for video are:
# "CGA"
video = "CGA"

# Emulate a composite monitor? Only meaningful for CGA.
composite = false

# Hard Disk Controller Type
# ----------------------------------------------------------------------------
# Valid options for hard disk controller are:
# "None"  - No hard disk controller will be present
# "Xebec" - Emulates the IBM/Xebec 20MB Fixed Disk Controller

#hdc = "None"

# Options for the CPU Validator module.
# ----------------------------------------------------------------------------
# You must have an Arduino8088 connected via USB to utilize
# the validator. For more information, see 
# https://github.com/dbalsom/arduino_8088
