• I'm sorry, but an exception occured while executing your Ren'Py script.
  ScriptError: could not find label 'start'.
  
  While running game code:
  - script at line 84 of renpy-6.4.0/common/00mainmenu.rpy
  ...And so on, it's a long error description.

Some users have reported problems with the SFK2 XXX patch, so I hope this information helps:

• If you can't install the patch because "bytecode.rpyb is the wrong version", delete the bytecode.rpyb file - the file was created when the game was run before running the patch. Delete the file (located in the /game/ directory), then install the patch before you run the game again.
• If you've tried installing the patch and gotten errors, it shouldn't cause problems, but you may have to delete the game, and download an unaffected copy from your account history on DLsite.com.
• This is probably obvious but, the patch is only for that specific game - the SFK1 patch is only for SFK1, the SFK2 patch is only for SFK2, and so on, so make sure you download the correct patch.
• The patch is for the full purchased English version only - downloaded from eng.dlsite.com. It won't work on the trial version, or the Japanese version. I can only imagine what kind of errors you would get.
• Finally, the xxx-patch is free bonus content offered by me alone. It's not included in the purchase price of the game, and the patch is not supported by DLsite.com, so any technical support issues regarding the patch should be directed to me.
