Reading the Client Version

The 0x08 Hello packet in Among Us contains the client's version number in an encoded format between offsets 4 and 7.

08 00 01 00 46 d2 02 03 08 75 73 65 72 6e 61 6d 65
            |---------/
            |
            Version number (50516550 in this case)

This version number is encoded using the following formula:

int version = year * 25000 + month * 1800 + day * 50 + revision

// Example

int version = 2020 * 25000 + 9 * 1800 + 7 * 50 + 0 // = 50516550

The values year, month, day, and revision are all hardcoded values within the game and are all reflected in the top-left corner of the screen.

To decode the version and retrieve the separate units, use a method similar to the following:

int year = floor(version / 25000)
int month = floor((version %= 25000) / 1800)
int day = floor((version %= 1800) / 50)
int revision = version % 50

Note: Do not expect the version sent in the 0x08 Hello packet to match the version displayed in the game. There are multiple compatible versions that a client or server may have, the one sent to the server is simply its broadcast vesion.
