Online Play Module
By Rick Billings
Now you can play Second World War at Sea: Coral Sea online with the VASSAL engine. You need to own the game to use this module.
Fill out the order form ($0 purchase) just like any other product, with your real name and address, and get the module in nanoseconds (a few nanoseconds ... these are big files).
