Yes, finally managed to get Battle Isle 2 supported. Battle Isle 2 requires the Scenery CD which added serial direct link support. while it allows for up to 6 players over serial connections, I'm currently only supporting 2 for now as this would require some rewriting of the serial relay server, but it is a possibility after the client and server are released. You can configure the game manually or based on the GOG.com setup. Z is supported, but I had to make a change to the client to allow the client to build the batch file "Z.BAT" which the game requires you to run so it won't be available until CGA 4.0 comes out. Which is getting closer.
With that being said, I have made a lot of progress on both the new client and sever. Some updates to the server include, self registration and online status updating when it starts, actually being able to connect to your own dedicated server when it's running on your own LAN (can't believe I never noticed this one!!), dynamic IP update support and many performance and stability updates including a massive performance increase in the serial relay server (games such as Jurassic War are actually playable now).
