# Data options

SEGA games receive content updates through option folders rather than direct game file updates.

For CHUNITHM, official options are named `A???`, where `???` represents a sequence of numbers.
Community-created options often use letters instead of numbers to differentiate them from official releases.

After downloading option files, extract them into your game's `Option` folder.

    📂AppData
    📂Option
    ┣━📂A001
    ┣━📂A121
    ┣━📂A131
    ┗━ etc.

Option numbers don't always follow a sequential pattern
It's common to see the numbers jump, for example `A113` then `A121`

The `A001` option folder may be required for network connectivity
