Effective immediately, the toggle for "EnableCutsceneSkipDelay" in the BuddhaDefault.cfg file, located at \Data\Config in your install directory, may be set to "false". If you do so, runs you make are to be submitted to the "Modded" category.

Speedrunning is about fun. Stacking isn't a particularly competitive game, and allowing the change of config file will mostly remove the unfun RNG element of runs. I say mostly, because you can still randomly skip the title cards at the beginning of cutscenes, and we don't really know how or why that happens, but missing title card skips no longer destroys your chances at a world record.

There are two ways to accomplish this.

Manual Method: Open your Stacking directory in Explorer/Finder. Navigate to \Data\Config, and open BuddhaDefault.cfg in your favorite text editor. Scroll all the way to the bottom of the file, and you'll find "EnableCutsceneSkipDelay=true". Change true to false. Save the file and close. You're done.

Still Manual But Less Involved Method: Retrieve the BuddhaDefault.cfg file located in the Resources section on this game's speedrun.com page (It's to the left). Open your Stacking directory in Explorer/Finder. Navigate to \Data\Config, and replace BuddhaDefault.cfg with the copy you downloaded from here. You're done.

Happy stacking!
