how to find the exact location inside the debugger
When breakpoint pauses emulation, right click here
It will open Hex Editor in ROM File view at the wanted location.
Another way is to copy C608, Ctrl + G to it in NES Memory view, right click on the byte, select Go Here In ROM File.
Another way is to set "ROM offsets" checkmark in debugger, manually copy ROM address, then Ctrl + G to it in ROM File.
And one more way is write down several bytes on the left of the instructions, then Ctrl + F them in ROM File.
