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.

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)

I was also thinking a something like that. Does it works?

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.
