I have it working now.
first I change the command line for the game that I want to make a preview for from:
-rollback-snapshot-period 600
to
-rollback-snapshot-period 6000
that way I have plenty of time for the savestate.
then resync the games.
Next Play games to get save state. I start game and do not touch any buttons allowing the built in demo to run.
once you make the save state of what ever games you want go back to hakchi>tools>Save-State Manager once opened export the save state to a working folder.
I personal have a thumb drive dedicated to just this so in the root of the thumb drive I have a folder I created and names Classic Demo. export my save states to this folder.
once you have exported your save states open the folder in which you exported them.
Using 7zip or WinRAR open the save-state. navigate to the rollback folder and extract.
open the extracted "rollback" folder you will find 0.inputs, 0.break, 1.input, 1.break,2.break,sram.hash.
Rename:
0.inputs to A.inputs
0.break to A.inputs.state
1.input to B.inputs
1.break to B.inputs.state
I delete 2.break and sram.hash. I delete 2.break because it does not have a 2.inputs to go with it.
once you have done this rename the "rollback" folder to "autoplay"
I personal use hakchi debug portable so I am not going to tell you where to find the root of hakchi.
but you will need to navigate to hakchi>games_snes>"the game folder"
move the now renamed folder "autoplay" into the game folder
Now go back to the games in hakchi and
Change the command line back
-rollback-snapshot-period 6000
to
-rollback-snapshot-period 600
now your done just go into hakchi and resync your games.
I will have a folder in my drive that I will be upload the demos I made. The folder will be public so you can add your own. I do request everyone be respectful and please don't erase everything.
Included will be the coverart I am using as well.
