The DOSBox-X preservation pods run the original DOS builds of BattleTech 4.10 / Red Planet 4.10 inside an emulator whose bridged NIC is enumerated 100 above the host pod's last octet. A new checkbox on each game page (RP Death Race / Martian Football, BT Free For All / No Return) shifts every siteconfig address the page uses by +100 so the same pages control either version of the games: - Munga game connections (port 1501) target host+100; toggling the box drops and reconnects any requested pods at the new address. - Mission egg player and camera entries carry the shifted address. - The checkbox locks while a mission is loaded/running, like the other mission properties. Launcher / site-management traffic is untouched -- those services still run on the pod host itself. Pages share a pod's MungaGame, so the most recent page to toggle or enable wins if two pages fight over one pod. Verified end-to-end against vPOD: netstat shows the game connection move 127.0.0.1 -> 127.0.0.101 -> 127.0.0.1 as the box is toggled, and the egg received by vPOD carries pilot=127.0.0.101. All 103 diff tests pass. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
