Have you tried hiring developers to do the work that you want?

I just cannot understand the entitlement of demanding some open source developer must do particular unpaid work that users are demanding.

With open source, you can fork the project.

It should be okay for an open source maintainer to say “no”.

Perhaps disconnecting the RF antenna, and replacing it with an appropriate termination?

Yes, but does that still count as “modern”?

I think you mean Tactics Ogre. Although it’s a spinoff of another game called Ogre Battle.

Maybe each server is hosting a different area in the game, and they are connected by portals. Would need a way to transfer users and their inventory to another server.
