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 instructions. Several forms are supported:

  asm                     Print one instruction at the Program Counter register

  asm <addr>              Print one instruction at <addr>

  asm <addr> <n>          Print <n> instructions starting at <addr>

  asm <addr> <n> <flags>  Print <n> instructions starting at <addr> with flags
    - If flags bit-3 is set (i.e. & 0x04): also print binary instruction data
    - If flags bit-2 is set: prefix each instruction with its memory address
    - If flags bit-1 is set: prefix each instruction with a counter from <addr>

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 /NxM <addr>   Print <N> rows of <M> 32-bit 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>
  mem /NxMd <addr>  Print <N> rows of <M> 64-bit double-words at <addr>

write
  Write values to memory. Several forms are supported:

  write <addr> <value>    Write a (1) byte value to <addr>

  write <addr> b <value>  Write a (1) byte value to <addr>
  write <addr> h <value>  Write a half-word value (2 bytes) to <addr>
  write <addr> w <value>  Write a word value (4 bytes) to <addr>
  write <addr> d <value>  Write a double-word value (8 bytes) to <addr>

translate
  Translates virtual memory addresses to physical memory addresses. Memory
  read/write breakpoints must operate on physical addresses, in contrast to the
  memory read/write commands and execution breakpoints that operate on virtual
  addresses.

  translate <virtual address>  Print the 32-bit physical address for the
                               provided <virtual address> argument.

bp add
  Adds a breakpoint at a given address. Several forms are supported:

  bp add pc                  Add a breakpoint at the Program Counter, triggered
                             on EXEC, READ, and WRITE.

  bp add <addr>              Add a breakpoint at <addr>, triggered on EXEC,
                             READ, and WRITE.

  bp add <addr> <n>          Add a breakpoint starting at <addr>, extending <n>
                             bytes, triggered on EXEC, READ, and WRITE.

  bp add <addr> <n> <flags>  Add a breakpoint starting at <addr>, extending <n>
                             bytes, with specified trigger flags.
    - M64P_BKP_FLAG_READ = 0x02
    - M64P_BKP_FLAG_WRITE = 0x04
    - M64P_BKP_FLAG_EXEC = 0x08

bp trig
  Prints the reason for the most recently activated breakpoint trigger. Memory
  read/write breakpoints will indicate the hit address.

bp rm <addr|index>
  Removes a breakpoint by address or number.

bp list
  Lists all breakpoints.

exit|quit
  Stop emulator and quit debugger
