The DLL now reads openfut.cfg from its own directory on DLL_PROCESS_ATTACH and uses the IP it contains as the redirect target instead of hardcoding 127.0.0.1. Falls back to 127.0.0.1 if the file is absent. The launcher writes openfut.cfg alongside version.dll when deploying, and the Setup tab exposes a "Redirect IP" field with an "Update" button that rewrites openfut.cfg in-place without redeploying the DLL. Useful when running the emulator on a different machine on the LAN. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
