Issues fixed[edit]

Item gets stuck on the cursor[edit]

Throughout the game you will encounter a snack bar owner to whom you have to bring an item. However, the item may get stuck on your cursor.

The exact cause of this issue is currently unknown, but it may be necessary to let the character animation complete before clicking any item. If you run into this issue you can't do anything except reloading a previous savegame.

Quicktime can't find video files[edit]

During certain parts of the game a Windows Explorer message may pop up stating that Quicktime couldn't find the video file the game wants to play back.
  1. Make a full copy of the 2nd game disc on your PC as an iSO file. You can use CDBurnerXP to do this.
  2. Extract your ISO file to a new folder with 7-Zip or a similar software.
  3. Open the folder and navigate to ./Game/Media.
  4. Copy all files with the .mov extension into the parent directory (./Game).
  5. Use Folder2Iso or a similar software to recreate the ISO file with your changes.
  6. You should be able to mount your new ISO file as virtual drive by simply opening it with Windows Explorer once. From now on, this file will replace your original 2nd game disc.
