Patch.tjs and Xp3filter.tjs are essential files for Train Simulator, and their importance cannot be overstated. Here are a few reasons why:

: While the standard Kirikiri SDK does not enforce encryption, almost all commercial visual novel developers inject custom encryption keys into their .xp3 tables to prevent asset theft and unauthorized distribution. 🔑 What is xp3filter.tjs ?

While both files use the scripting language native to the Kirikiri engine, they serve entirely different operations during a game's initialization sequence.
