I'm making a lua script for DeSmuMe. I want to use this command to save a value on save state: savestate.registersave(function() return frame end). But the emulator gives me this error: :50: attempt to call field 'registersave' (a nil value). Why? How can i solve this error?

There is no function in DeSmuMe that is being called when you save a state. The only thing you can do is use lua itself to save a state (with the savestate.save() and savestate.load() functions).

Attach to keyboard key that you use to save a state?

I try to generalize them and turn into something clear and reusable. I hate depending on unpredictable and having to make lottery guesses. Any problem can be solved by systems thinking and acting.

I need to make save state and reload back all the value...but the problem is that i can't relaod the correct "frame". I can pass you the code if you want...so you can understand...

How? Here's my example but it doesn't fire consistently for some odd reason. 
Language: lua
prev_keys = input.get()
function lol()
	keys = input.get()
	if keys["shift"] then
		if keys["F1"] and not prev_keys["F1"] then
			print("Hey you saved state 1!")
		end
	end
	prev_keys = keys
end
gui.register(lol)

The solution wasn't a solution to the generic problem of saving a value on a savestate. It was a solution to the specific problem which could be solved without that feature.

Yes, exactly as it said
