PixelTweaks

Players who want fewer rough edges in their Pokémon game can use PixelTweaks for a collection of adjustments. Shiny Pokémon play a sparkle sound when they spawn, and the battle music and sound effects for specific Pokémon can be replaced through resource packs. Defaults for battle music follow the Legends: Arceus style, and healers drop themselves in a broken state rather than an aluminium ingot.

Item tooltips show lore, and holding Sneak splits long text onto several lines after a set length of 60 characters. Two new game rules, doPokemonSpawning and doTrainerSpawning, control spawning, and specific worlds can have spawns disabled. Zygarde cells spawn again, as they did in version 1.16. JEI integration lists Pokémon drops and Pokeloot infuser recipes, and the backpack integration covers items carried in backpacks from other mods during battle.

The mod needs the game it extends, because the tweaks change its items and features. Either side can run it, and neither needs it. Files are published for Forge and NeoForge, across 3 release versions 1.16.5 – 1.21.1, and the mod is open source under the MIT License.
