Console Options
-------------------------------------------------------------------------------

At startup, the mupen64plus program will look for a user configuration file
called 'mupen64plus.cfg'.  If this file does not exist, it will be created and
default settings will be written. If desired, an alternate config directory can
be specified using the --configdir commandline option.

Run 'mupen64plus --help' for a complete list of commandline options: 

 $ mupen64plus --help

Debugger
-------------------------------------------------------------------------------

Setup
=====

You must use a mupen64plus core library which was built with the DEBUGGER flag set.

Running
=======

Use the --debug command-line option to enable the console debugger.

The emulator mode should be set to "interpreter", as the dynarec seems to cause
issues when interacting with the debugging API. This can be done with the R4300Emulator
config setting or with the --emumode flag.

Usage
=====

Once the emulator boots, it will be paused by default. You will be presented
with a prompt as follows:

(dbg) 

The following commands can be entered:

run
  Unpauses the game.

pause
  Pauses the game.

step <num-steps>
  When paused, instructs the emulator to make a single step, or a series of
  steps if num-steps is provided.

regs
  Prints out general purpose register values.

pc
  Print current value of Program Counter register

pc-1
  Print previous value of Program Counter register

asm
  Print assembly language instruction at current PC location

mem
  Print memory values. Several forms are supported:
  
  mem <addr>        Print one 32-bit word at <addr>
  
  mem /N <addr>     Print <N> 32-bit words at <addr>
  mem /Nb <addr>    Print <N> 8-bit bytes at <addr>
  mem /Nh <addr>    Print <N> 16-bit half-words at <addr>
  mem /Nw <addr>    Print <N> 32-bit words at <addr>
  mem /Nd <addr>    Print <N> 64-bit double-words at <addr>

  mem /NxMb <addr>  Print <N> rows of <M> 8-bit bytes at <addr>
  mem /NxMh <addr>  Print <N> rows of <M> 16-bit half-words at <addr>
  mem /NxMw <addr>  Print <N> rows of <M> 32-bit words at <addr>
