The Checklist:

The Checklist is a Key Item you'll get at the beginning of the game after the intro ends.

The Checklist is how you'll keep track of the current time, the characters you've recruited, how many cameras you've defeated, and the current level of your Vending Machines.

It'll also hold two Quality-of-Life options: Max Battle Members and the Copyright switch.

You can have a total of 8 party members on your team at any time; any other members you recruit will be placed in Reserve.

The Max Battle Members option will allow you to change the number of members you can have on your team at one time, starting with 1 member at the lowest and 8 members at the highest.

Let's say you currently have 8 members in your party, and want to change it to 4. The game will keep your first 4 members, while sending the other 4 back into reserve.

The Copyright Switch is self-explanatory; It replaces the copyrighted music the game normally uses with non-copyrighted music.
