Ported from sacredK with module-relative addresses, hooks by exported name and a SHA-256 check of the six game modules (Community Patch 2.65.1). Borderless windowed at monitor size replaces exclusive fullscreen, whose focus loss during loading made the game quit and crash on exit. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
