I'm using the Mame Debugger to communicate between a running program and my development tools.
I send strings to the debugger from the tools to alter parts of memory for 'realtime' update. This works well. I can FILL parts of RAM, and I can load in files to ROM areas.
However when I try to FILL rom areas, I can't get it to work. I think I'm missing something fundamental. (I can't get this to work from LUA scripting either).
when I FILL to eg $f000, which is ROM space, the command completes, but when I examine the memory there nothing has changed.
I've tried postfixing different memory spaces to the address, but I can't get any results.
Any ideas? Thank you!
