Software stop simulation

Hi all!
There is a need to programmatically stop the simulation, because Proxmark 3 easy does not have the ability to change blocks in the recorded memory of the emulator or is it?

There is this version, it works under windows 10

I am trying to emulate a Mifare Ultralight card
and i need to change some blocks in simulator memory or change data in json file and reload it for simulation.

Is it possible to execute the command
hf mfu wrbl for data located in the memory of the simulator, I load the json file

local new_json = json.encode(json_data)
local fname = string.format("%04X.json", i)
local f = io.open(fname, "w")
f:write(new_json)
f:close()

core.console("hf mfu eload -f " .. fname)
and run the simulation
core.console("hf mfu sim -t 2 --uid 04CF698A014A80")

but because I can not change the data - write to the emulated memory, I change the data in the json file and turn on the simulation again.
how to programmatically stop simulation or write modified blocks to simulator memory?

Re: Software stop simulation

This is what happens when you don't read the rules.    This is the introduction section.
