After the patch, many people like me faced the problem of passing the room with the cube. More precisely, after passing the "rotten room", the new door did not unlock. I waited a long time for the issue to be resolved, but without waiting, I downloaded the repack of the previous version and loaded my auto save before jumping into the hole.

For those who are too lazy to download the previous version of the game, I am attaching the save files with the unlocked second part of the cube.

Drop the contents into "C:\Users\username\AppData\Local\SilentHill2\Saved\SaveGames\ folder with numbers"

Don't forget to change the settings for yourself.
