Applies to Mystical Realms Translation & Fixes 1.0.1 for Minecraft 1.21.1.

Requirements

Minecraft	1.21.1 exactly (pack format 34)
Loader	any — NeoForge, Fabric, Vanilla
Required mods	none

The pack has no dependencies and no hard requirements. It does not need the mods it translates to be installed — an unused lang file is ignored by the loader.

It is loader-agnostic precisely because a resource pack is assets only. Nothing it contains is tied to a mod loader.

Not for other Minecraft versions

Pack format 34 is 1.21.1 only. The pack will not load on another version, and there is no separate build per version. The mod set of a modpack changes substantially between versions, so translations for one version's mods are meaningless on another.

Interactions

With mods that ship their own Spanish

Minecraft merges lang files across all loaded packs rather than overwriting them, so this pack supplies only missing keys and never replaces a mod's own translations. Both can be present at once. See Translations.

With other packs fixing the same files

Load order decides which override wins. Overlapping fixes for the same file are worth avoiding, though in practice only this pack touches these four.

With mystical_realms_modpack_fixes

They are complementary halves of one feature. The mod patches Better Villager Animations to read a Spanish dialogue table from a resource pack at runtime; this pack is what supplies that table.

	Table supplied here	Overlay works
Mod installed, this pack installed	yes	yes
Mod installed, this pack absent	no	no — silently
Mod absent, this pack installed	unused	n/a
Neither	no	no

The failure mode is worth knowing: with the mod installed but no table present, the overlay does nothing and logs nothing. There is no warning. If you install the mod expecting Spanish villager dialogue, install this pack too, or the feature will appear to be broken.

The mod requires the client language to be exactly es_es for this to apply.

What this pack will not do

• It will not translate a mod with no English text. Translation starts from the mod's own en_us.json; if a mod has no English strings, there is nothing to translate.
• It will not translate hardcoded Java strings. That is what the Better Villager Animations patch above is for — no resource pack can reach text inside a mod's code.
• It adds no gameplay content. No items, blocks, recipes, advancements or sounds.
• It adds no items or blocks of its own, and appears in no tab. It is invisible until some text is Spanish or an error stops appearing.
• It does not fix upstream. The four fixes are local overrides. A future version of the mod may fix them properly, at which point the override is dropped.

Coverage caveat

Translations track the wording of each mod's current English. When a mod rewords a string, the key changes and the pack's Spanish for it becomes stale until re-translated. There are 93 namespaces and roughly 14.8k keys, so occasional drift is expected between releases; the per-release list is in CHANGELOG.md.

Performance

Negligible. It is a set of static JSON files loaded once at startup, and 188 guidebook entries are only parsed when a book is actually opened. The translations add no per-frame cost and no memory overhead beyond the text itself.

Provenance

Written against a specific modpack instance and validated there. It is usable anywhere, but that is where it was tested.
