Non-Stop Boss Rush
Cave Story+ has a hidden Non-Stop Boss Rush mode that was never used in the final game, but can be accessed with a few tweaks.
- Open up Booster's Lab.
- Click on File, then Load.
- Navigate to your Cave Story+ folder.
- Open the "data" folder, then "boss", and finally "mod".
- Click on stage.tbl and select "open".
- In the map listing double-click on "13 - ***Boss Rush*** - Start".
- Click on "script".
- Scroll until you see the words "THIS IS STARTING NEW GAME SCRIPT!".
- Underneath that line you will see "#0200". Change that to "#0199".
- Next you need to look for the text "#0201". In the line directly above that you should place the following:
- Click on File, then Save All.
- Start the game.
- Select "Challenges", then "Boss Attack", and then "Start Game" (the Boss Rush needs to be unlocked for this to work).
- Select "Yes" when the game asks you if you want to "play Non-Stop mode" .
The Non-Stop Boss Rush mode does not save times, however it does still record replays.
