I have been toying with FCEUX's debugger & tools but haven't figured out a way to do this. I would like to lock a particular byte in memory at a specific value. Is there a simple way to do this? Currently, I'm just leaving the hex editor open and when the value in question gets to low, I reset it back to FF but it would be nice if I could just lock the value and not have to constantly change it manually. (It's probably obvious but the # I'm wanting to freeze is hit points.) Is this something I would have to find a cheat for or can it be done with the memory editing tools?

Huh. I can't believe I never tried right clicking before.

Just to be clear... when I freeze the value in question, it doesn't stop my HP from continuing to run down. However, the value at that location corresponds to the value of my HP ie. if I enter FF, my HP changes to 255. Does freezing actually lock the value in? I assume so but just want to make sure that it doesn't just keep it from visually changing in the hex editor. I presume maybe there's another location that affects the HP rundown as well, I just need to do some more digging.
