The ROM-Wack interface (which you get to by pressing the ''right'' mouse button at any Guru Meditation error), is available on the Amiga's serial port at 9600, 8-N-1.

A basic concept is that there is a single memory pointer (called 'MP' in the following
documentation) that acts as the base address for almost all commands.

On entry, MP == PC.

<pre>
XXXXXX # Set MP to XXXXXX
-XX # Subtract XX from MP
+XX # Add XX to MP
:XX # Set default dump length
^ # Dump memory at MP
< # Decrement MP by the default dump length, then dump
> # Dump memory at MP, and increment MP by the default dump length
. # Alias for '>'
!aX # Change address register X
!dX # Change data register X
!u # Change USP
</pre>

<pre>
? # List the 'long' commands

alter # Edit memory at MP
= # Alias for 'alter'

boot # Reboot the Amiga

clear # Clear breakpoint at MP

fill # Fill work space with a pattern

find # Find a pattern from MP

go # Start execution from MP
limit # Set top of work space
regs # Show all registers
reset # Clear all breakpoints
resume # Start from the trapped instruction
^D
set # Set breakpoint at MP
show # Show all breakpoints
user # Change to user mode
</pre>
