looking for a way to save a state for every frame of the gameplay
It depends on which emulator you're using, but I guess it would be simple for BizHawk and Lsnes (for example):
Language: lua
while true do
--[[
YOUR CODE OR FUNCTION CALLS HERE
--]]
local savestate_name = string.format("bla bla bla %d", emu.framecount()) -- "bla bla bla" is anything you want, like your AI's name
savestate.save(savestate_name) -- IF BIZHAWK
exec("save-movie " .. savestate_name .. ".lsmv") -- IF LSNES
emu.frameadvance()
end
Tho, I'm not sure if BizHawk's savestate.save(string path) needs the full path for the file or it can save in .\[console]\State
Edit: savestate.save(string path) saves in the same folder of your script, so you can make:
Language: lua
local savestate_name = string.format("AI_savestates\\bla bla bla %d", emu.framecount())
Thank you very much, brunovalads. It works like a charm.
Yes, I am using BizHawk.
Hi,
Now I am working on my AI project and looking for a way to save a state for every frame of the gameplay in order to resume to any state I want without running from the start of the movie.
Any pointer to an existing project or a lua script will be greatly appreciated.

Thank you very much @Koh1fds and @Amaraticando.
Now I can create perfectly synced screenshots and Input Log.
+image sequence writer
+display frame counter

Thanks again.
From your post it's not clear what you want. Do you want a sequence of screenshots with input display? Or a video with input display?
In any case, this should do the job:
1) Go to the View menu and select what should appear on screen and where.
2) Go to File > AVI/WAV and select Capture OSD to make those drawings (and Lua drawings too) appear in the dumped video.
3) In the same place, go to Config and Record AVI/WAV. You can choose the video format and even the image sequence writer.
4) Go to Record AVI/WAV to start the job and to Stop AVI/WAV when you're done.
Hi. thank you for answering.
I want screenshots which syncs to the records in "Input Log.txt" file of the .bk2.
Edit: I don't want screenshot with overlayed text because I would like to use the pure screenshots to train my bot.
I tried to record the .bk2 file along with AVI but it seems the frames from the AVI file don't sync with the records in the bk2 file.
Pause the emulator -> start movie replay (autopause on last frame) -> start avi recording -> unpause emulator -> movie will autostop on last frame -> stop avi recording
This way it will be 100% sync
edit: you can also record avi with frame counter, input display and other stuff
Thank you very much.
I still have some questions?
1. By start movie replay, you mean start record movie (.bk2 file)?
2. After the unpause emulator is when I play the game?
3. How to indicate the last frame? let's say I want to stop recording at this point so I just go to menu and select save AVI?
Thanks again
Hi,
I would like to know that if it is possible to record the control input e.g. Input Log.txt in the .bk2 file which each record has a screenshot that syncs to it. If it is possible, how could I do that?

PS. I am very new to the Bizhawk and emulator world, I don't know if this is a very straightforward question, but I have tried to search for the solution.
Thank you very much.
