The “dlc_music.bank” and “dlc_sfx.bank” files contain the new audio content added in the free “Chapter 9” DLC that was released for Celeste last month. These files are there because Steam automatically updates the games in your library to the latest non-beta version available, and the latest version includes the new DLC. However, the Celeste FMOD Studio project available from our website is from an earlier version of the game that does not include the DLC. As a result, when you rebuilt the banks, you overwrote the game’s bank files with older versions that did not include all the content that the game expected. When the game tried to load these banks, it could not find the content it expected, and crashed.
In order to use the Celeste FMOD Studio project to connect to your game using live update, you must set Steam to “update” Celeste to an earlier version. To do this:
- Right-click on Celeste in your steam library, and select “Properties” from the context menu.
- Click on the “Betas” tab.
The Betas tab was originally designed to allow users to test specific beta versions of games, but can also be used to roll back to specific older versions of games in some cases.
- Click on the “Select the beta you would like to opt into” drop-down menu, and select “outdated-126.96.36.199”.
- Close the window.
Steam will then automatically download and update your game to that earlier version, which is compatible with the Celeste FMOD Studio project.
We’ll update our manual to include these extra steps. Thanks for letting us know about this issue!
