Yapped (short for "Yet Another Param Parser and Editor for Dark Souls") is a table editor for FromSoftware games. While earlier versions supported Dark Souls III and Sekiro, Yapped 1.1.2 is specifically optimized for Elden Ring (version 1.05 through 1.09+).
In simple terms: all of Elden Ring’s data—damage values, FP costs, weight, scaling, even boss health pools—lives inside files called "regulation.bin." Yapped 1.1.2 unpacks this file into human-readable spreadsheets. You change a number, save it, and your game transforms.
Cause 1: You edited a critical field (like behaviorJudgeId) incorrectly.
Cause 2: You saved the regulation.bin while the game was running (never do this).
Fix: Restore your backup regulation.bin and reapply edits slowly, testing after each change.
This guide covers installing, configuring, and using Yapped 1.1.2 (assumes a typical desktop development environment). It gives quick setup steps, common commands, configuration tips, troubleshooting, and examples.
While not specific to Yapped 1.1.2, some game modding research papers discuss param editing methodology:
