This utility downgrades your copy of STA Anniversary to V3.0 - CL 46,793. This is the first release of Anniversary, which is extremely buggy and as such highly exploitable for tech and skips. Please note that this was before performance was optimized, so you will need a reasonably powerful computer to get a competitive framerate. You MUST use this tool if you want to run the Downpatched category.

This patcher will only work for the version listed in the patcher's filename. If a newer version is released, you'll have to wait for me to update the patcher, unfortunately. You can check which version of STA Anniversary you're currently on at the title screen.

To use the patcher, simply extract it anywhere, update your copy of STA Anniversary to the latest version, navigate to the game directory (Right click in Steam, go to "Manage", then "Browse local files"), copy all files within into the "input" directory of the patcher, and run "patch.bat". When it's done, copy all files in "output" back into your game directory and replace all when prompted. You should now be running 46,793. To reverse this, go to STA's properties in Steam, then "Installed Files", and finally click "Verify integrity of game files". Wait for it to finish downloading and installing and you'll be back on the latest version.

If you have any issues, just @ me in the STA speedrunning Discord.
