A pack that does not appear is almost never broken. The game loads packs by looking for a specific folder layout and specific filenames, so a pack that is one level too deep, in the wrong directory, or missing one required file is simply invisible. Work down this list in order: the first three fixes account for most cases.
This is the big one. Many zip tools extract to MyPack/MyPack/clip1.wav, and some packs ship as a zip inside a zip. Recent game versions usually still find nested files (we tested v0.5.1), but the flat layout is the one that always works. Open the folder you dropped in: you should see the audio and images immediately, not another folder with the same name.
Each pack type has its own directory: packs_voice for voice and dub packs, packs_player for contestants, packs_judges, packs_studio, packs_menu, and packs_chatter. A judge pack in packs_voice will never show up. Open the folders from the game's main menu to be certain you are in the right one.
Audio dumped straight into packs_voice is not a pack. Every pack is one folder, and that folder's name is what the game shows as the pack name. Make a folder, move the files into it, restart the game.
A dub pack must contain a file named dub_video.ogv, and it has to sit at the top of the pack folder, not in a subfolder. OGV (Ogg Theora) is the only video format the game plays, so an MP4 or WebM will not work no matter what it is named. Convert it with a tool like FFmpeg or HandBrake and try again.
Dub Mode arrived in version 0.5. On an older build a dub pack has nothing to load into. Chatter packs are the same story: the Twitch integration is 0.5 and up. Check your version on the game's main menu and update from your itch.io purchase page if you are behind.
Each type has a minimum the game will not start without:
judge1 through judge5. Four is not enough.player.config_chatter.ini or .cfg, and every audio file it references actually present in the folder.Clips must be WAV, MP3, or OGG, and WAV must be uncompressed PCM — a WAV using a compressed codec will not play. Clips also have to be under 60 seconds. One bad file does not usually hide the whole pack, but it does explain a pack that loads with gaps.
If two files share a basename in different formats — line1.wav and line1.mp3 — the game loads WAV over MP3 over OGG and ignores the rest. Rename one of them if you meant to have both.
Our install guide walks through the folder layout with an example tree, and the official manual documents every pack format file by file. Compare the pack's contents against the requirements for its type, and if it still refuses to load, ask whoever made it.
