Alpha pre-release warning! This is not a full release version and a lot of stuff might still go wrong.
This plugin allows you to open theme selection menu before each mission which allows you to replace the original theme with the chosen theme from Patapon 3. Note that the mod is not perfect as I had to remake the entire theme scheduler myself and due to framerate loss and other game delays the custom themes need to get constantly synced so there could be a bunch of theme pauses and so on.
To open the menu before each mission press f6 on your keyboard to open theme selection menu. Use arrow keys and enter to choose specific theme you want. WARNING: The keybinds are not disabled for the game when menu is open so make sure to check if your army is intact after theme selection!!
The plugin has a custom theme support as well! "All" you have to do is convert your own custom theme into the general files structure. For reference inspect the plugin\PataponMusicMenu\Themes folder. The folders starting with 2 numbers (01 - 99) will be read as theme menu entries and loaded accordingly (you need to make sure that the .ogg files are decoded properly by the plugin, check BepInEx console for warnings upon choosing the theme). In case of issues ping me on Patapon Replay Modding Discord.
Copy the BepInEx folder from the download into your game's folder. You also need to download PataponThemeLibrary for this plugin to have some themes to choose from (check dependencies)!
