During August 2025, Hardcpp developed a configuration bundle for Beat Saber mods in the DanTheMan827/bsqmods repository, targeting version 6.4.1. The work focused on asset and configuration management, delivering a unified set of JSON assets and SDK configuration files to support key mod components such as menu music, notetweaker, gametweaker, and multiplayer. By streamlining the integration process for both QA and partner developers, Hardcpp enabled easier mod development and compatibility across the ecosystem. The project involved five patch-level updates, reflecting a focused, in-depth effort on a single feature rather than broad bug fixing or multi-feature expansion.
