You can put repeated debugger steps (like looking up correct addresses & 
"savebin" calls) to a debugger script, and just call that. like this:
------------------------------------------------------
> parse save-neo.ini
Reading debugger commands from 'save-neo.ini'...

'parse' or 'p' - get debugger commands from file
Usage:  p [filename]
	Read debugger commands from given file and do them.
	Current directory is script directory during this.
	To specify directory to be used also for breakpoint
	scripts execution, use '-f' option for 'cd' command.
-----------------------------------------------------

Virtual registers can be used e.g. to hold address values you've looked 
up / calculated, like this:
-----------------------------------------------------
> r v0="($200)+32"
  value at ($200).l = $e007ce
- '($200)+32' -> $e007ee

> r
....
Virtual registers:
  V0 00e007ee  V1 00000000  V2 00000000  V3 00000000
  V4 00000000  V5 00000000  V6 00000000  V7 00000000
-----------------------------------------------------
