| Tool | Purpose | |------|---------| | | Revert 1.6.640 to 1.5.97 or 1.6.353 | | Root Builder for MO2 | Isolate mods from game root to avoid update damage | | Skyrim Version Patcher | Auto-update mod DLLs to target version | | Backup SSE Executable | Small batch script that copies SkyrimSE.exe on launch | skyrim update 1.6.640
