Unused strings

This article was written 28th of July 2025 and contains information valid at given time.

List of strings not used by the source code

These strings with their respective STR_ number are not currently loaded by the game from localisation files.

Changing these in strings with numbers written below in existing translation or translating them into new localisation will have no visible effect for the players. In commented style are given hints pointing to the literal same strings with different number, that are used in the game.

Checking for yourself

Running simple python script does the trick:

# OpenRCT2 translator's helper utility
#   analyze what strings are currently not in use
