Contestant Packs, currently also called Player Packs, define the character shown at the podium. They can include an image, a name, colors, an introduction, and optional reaction audio.

Open the game files from the main menu and create a dedicated Contestant Pack folder in packs_player.
Use a PNG or JPG named player. PNG is preferable when you need transparency.
The game does not scale the image. Aim around 500 pixels wide by 1000 pixels tall, then add transparent space at the bottom if the character needs to sit higher.
Add audio files, then choose them in the Customization menu for introduction, win, loss, and score events.
There are nine possible reaction events, but each event uses one audio file. Test the character image before filling every slot.

Quick answers
Keep image layout and event audio separate while testing.

A simple image and a single assigned line prove the Pack works before you create a full cast.
