SYNOPSIS

             [-t statefile] file

DESCRIPTION

     mgba-qt is a Game Boy Advance emulator.  The options are as follows:

     -1      Scale the window 1×.

     -2      Scale the window 2×.

     -3      Scale the window 3×.

     -4      Scale the window 4×.

     -5      Scale the window 5×.

     -6      Scale the window 6×.

     -b biosfile, --bios biosfile
             Specify a BIOS file to use during boot.  If this flag is omitted, mgba-qt will use
             the BIOS specified in the configuration file, or a high‐level emulated BIOS if none
             is specified.

     -C option=value, --config option=value
             Override the given config option with value.

     -f      Start the emulator full‐screen.

     -g      Start a gdb(1) session.  By default the session starts on port 2345.

     -l loglevel
             Log messages during emulation.  loglevel is a bitmask defining which types of
             messages to log:
             •   1 – fatal errors
             •   2 – errors
             •   4 – warnings
             •   8 – informative messages
             •   16 – debugging messages
             •   32 – stub messages for unimplemented features
             •   64 – in‐game errors
             The default is to log warnings, errors, fatal errors, and status messages.

     -p patchfile, --patch patchfile
             Specify a patch file in BPS, IPS, or UPS format.

     -s n, --frameskip n
             Skip every n frames.

     -t statefile, --savestate statefile
             Load initial game state from statefile.

CONTROLS

     The default controls are as follows:
     A              x
     B              z
     L              a
     R              s
     Start          ⟨Enter⟩
     Select         ⟨Backspace⟩
     Load state     F1–F9
     Save state     ⟨Shift⟩‐F1–F9
     Frame advance  ⟨Ctrl⟩‐n

ENVIRONMENT

     XDG_CONFIG_HOME
             The location where mgba-qt will look for the configuration directory.  If not set,
             ~/.config is used.

FILES

     $XDG_CONFIG_HOME/mgba/config.ini
             Default mgba(6) configuration file.
     $XDG_CONFIG_HOME/mgba/qt.ini
             Default mgba-qt configuration file.
     portable.ini
             If this file exists in the current directory, mgba-qt will read config.ini and
             qt.ini from the current directory instead of $XDG_CONFIG_HOME/mgba.
