Creating a Classic Demo for an added game

Important: The following will only work with games running on the SNES Mini's Canoe emulator. Use "View > Sort by > Core" to determine if the game can display a demo.

This guide will outline the steps required for creating a demo that works with the SNES Classic Mini's "Classic Demo" mode.

Instructions

Updating game settings

• Connect your SNES Classic Mini to your computer via USB.
• Open hakchi and select the game for which you wish to record the demo footage.
• Click in the "Command line" field and locate -rollback-snapshot-period 600.
• Change 600 to a higher number, such as 60000.
• Ensure the game is ticked and click "Synchronize selected games..."

Recording a demo

• Connect your SNES Classic Mini to a TV/monitor and start the relevant game from the main menu.
• Once you have reached the desired point where you want your demo to end, press the Reset button to return to the main menu.
• Press down on the D-pad and then the Y button to save your gameplay as a suspend point.
• Once saved, turn off the SNES Classic Mini and plug it back into your computer.

Converting the suspend point

• Open hakchi and navigate to "Tools > Save-State Manager".
• Select the relevant save state (usually marked with a number in the "Save slots" column) and click "Export selected" to save it to your computer.
• Locate the file (it should have a .clvs file extension) and use a tool like 7-Zip or WinRAR to open the file and navigate to the following folder contained within:

Chrono Trigger.clvs/Chrono Trigger/CLV-U-ZJSQU/suspendpoint* (where "CLV-U-ZJSQU" is the game's ID and * is the suspend point number)

• Drag the "rollback" folder to your Desktop and then rename it to "autoplay".
• Open the "autoplay" folder and rename the .break and .inputs files as follows:
  • 0.break to A.inputs.state
  • 0.inputs to A.inputs
  • 1.break to B.inputs.state
  • 1.inputs to B.inputs
  • etc.
• The sram.hash file can be deleted.

Adding the demo to the SNES Mini

• Return to hakchi, right-click the relevant game, and select "Show in Windows Explorer" or press F4.
• Move the "autoplay" folder into this folder.
• Click "Synchronize selected games..."

Testing the demo

Connect your SNES Classic Mini to a TV/monitor and wait for Mario to appear. Once he reaches the relevant game, the demo should start as expected.

Note: If, for example, games are sorted by title, Mario will move through the games alphabetically, so it may take some time to test that the demo is working. Pressing "Start" to return to the main menu each time a demo starts will speed this up.

Additional notes

• Some guides on this process state that the "autoplay" folder should be saved to the "games_snes" folder. The game's default hakchi location is fine.
