# Notification localization Trophy notification subtitles use the configured console language. Trophy names still come from the game's metadata. The launcher trophy dialogs are unchanged. Edit `assets/localization/.json`, using flat UTF-8 string values: ```json { "trophy.toast.earned": "Trophy earned!" } ``` CMake converts the catalogs into C++ byte arrays in the build directory. The emulator parses the embedded catalogs once and falls back to `en-US.json` for missing translations. No language files or translation service are needed at runtime. Rebuild after editing a catalog. For local testing, rebuild `kyty_emulator`, choose a game's Console Language in the launcher, and unlock a trophy with notifications enabled. Installed system fonts provide non-Latin glyphs; the selected language needs an appropriate font on the host.
