General Debugger Commands

do – evaluates the given expression
symlist – lists registered symbols
softreset – executes a soft reset
hardreset – executes a hard reset
print – prints one or more s to the console
printf – prints one or more s to the console using
logerror – outputs one or more s to the error.log
tracelog – outputs one or more s to the trace file using
tracesym – outputs one or more s to the trace file
history – outputs a brief history of visited opcodes (to fix: help missing for this command)
trackpc – visually track visited opcodes [boolean to turn on and off, for the given CPU, clear]
trackmem – record which PC writes to each memory address [boolean to turn on and off, clear]
pcatmem – query which PC wrote to a given memory address for the current CPU
rewind – go back in time by loading the most recent rewind state
statesave – save a state file for the current driver
stateload – load a state file for the current driver
snap – save a screen snapshot.
source – reads commands from and executes them one by one
quit – exits MAME and the debugger

Memory Debugger Commands

dasm – disassemble to the given file
find – search program memory, data memory, or I/O memory for data
dump – dump program memory, data memory, or I/O memory as text
save – save binary program, data, or I/O memory to the given file
load – load binary program memory, data memory, or I/O memory from the given file
map – map logical program, data, or I/O address to physical address and bank

Breakpoint Debugger Commands

bpset – sets breakpoint at

bpclear – clears a given breakpoint or all if no specified
bpdisable – disables a given breakpoint or all if no specified
bpenable – enables a given breakpoint or all if no specified
bplist – lists all the breakpoints

bp[set]

[,[,]]

bp 45678,a0==100,{a0 = ff; g}
bp 3456,1,{printf “A0=%08X\n”,a0; g}
temp0 = 0; bp 567890,++temp0 >= 10

Watchpoint Debugger Commands

wpset – sets program, data, or I/O space watchpoint
wpclear – clears a given watchpoint or all if no specified
wpdisable – disables a given watchpoint or all if no specified
wpenable – enables a given watchpoint or all if no specified
wplist – lists all the watchpoints

wp[{d|i}][set]

,,[,[,]]

wp 23456,a,w,wpdata == 1

Registerpoints Debugger Commands

rpset – sets a registerpoint to trigger on
rpclear – clears a given registerpoint or all if no specified
rpdisable – disabled a given registerpoint or all if no specified
rpenable – enables a given registerpoint or all if no specified
rplist – lists all the registerpoints

rp[set] {}[,]]

rp {PC==0150},{temp0++; g}

Execution Debugger Commands

step – single steps for instructions (F11)
over – single steps over instructions (F10)
out – single steps until the current subroutine/exception handler is exited (Shift-F11)
go – resumes execution, sets temp breakpoint at

(F5)
gint – resumes execution, setting temp breakpoint if is taken (F7)
gtime – resumes execution until the given delay has elapsed
gvblank – resumes execution, setting temp breakpoint on the next VBLANK (F8)
next – executes until the next CPU switch (F6)
focus – focuses debugger only on
ignore – stops debugging on
observe – resumes debugging on
trace – trace the given CPU to a file (defaults to active CPU)
traceover – trace the given CPU to a file, but skip subroutines (defaults to active CPU)
traceflush – flushes all open trace files.

Debugger Expressions Guide

Numbers
Numbers are prefixed according to their bases:
Hexadecimal (base-16) numbers are prefixed with $ or 0x.
Decimal (base-10) numbers are prefixed with #.
Octal (base-8) numbers are prefixed with 0o.
Binary (base-2) numbers are prefixed with 0b.
Unprefixed numbers are hexadecimal (base-16).

( ) : standard parentheses
++ – : postfix increment/decrement
++ – ~ ! - + b@ w@ d@ q@ : prefix inc/dec, binary NOT, logical NOT, unary +/-, memory access
* / % : multiply, divide, modulus
+ - : add, subtract
<< >> : shift left/right
< <= > >= : less than, less than or equal, greater than, greater than or equal
== != : equal, not equal
& : binary AND
^ : binary XOR
| : binary OR
&& : logical AND
|| : logical OR
= *= /= %= += -= <<= >>= &= |= ^= : assignment
, : separate terms, function parameters
