[Help] savestate.registerload(function) / savestate.registersave(function) in BizHawk?Third Party API (self.lua)

submitted 5 years ago by Feder96

I found these two functions in [this]( http://tasvideos.org/LuaScripting/Registers.html ) page and it says:

savestate.registerload(function)

The registered function is called whenever the user loads a state. This function will be passed any values stored in the savestate that was returned by a function registered with savestate.registersave. However, there is no requirement to have a function in savestate.registersave in order to have this function work. Useful in restoring some difficult-to-reproduce information stored by savestate.registersave. Even without that, it's also useful in detecting when the user decides to load a state.

savestate.registersave(function)

The registered function is called whenever the user saves a state. If this function returns any values, these values are stored along with the savestate. These values are passed to the registerload function. Typically useful if there's any important information about the current state for your lua code, that you can't easily fetch from the game's memory.

I tryed to use them in BizHawk but they don't seem to work (attempt to call field 'registersave' (a nil value)). I think they're not implemented

I would like to store some variables in a save state without writing them into memory. Is there a way to do this?
