Steel Diver: Sub Wars (3DS) replacement server

Includes both the authentication and secure servers

Compiling

Setup

Install Go and git, then clone and enter the repository

$ git clone https://github.com/PretendoNetwork/steel-diver-sub-wars
$ cd steel-diver-sub-wars

Compiling using go

To compile using Go, go get the required modules and then go build to your desired location. You may also want to tidy the go modules, though this is optional

$ go get -u
$ go mod tidy
$ go build -o build/steel-diver-sub-wars

The server is now built to build/steel-diver-sub-wars

When compiling with only Go, the authentication servers build string is not automatically set. This should not cause any issues with gameplay, but it means that the server build will not be visible in any packet dumps or logs a title may produce

To compile the servers with the authentication server build string, add -ldflags "-X 'main.serverBuildString=BUILD_STRING_HERE'" to the build command, or use make to compile the server

Compiling using make

Compiling using make will read the local .git directory to create a dynamic authentication server build string, based on your repositories remote origin and current commit

Install make either through your systems package manager or the official download. We provide a default rule which compiles using go

To build using go

$ make

The server is now built to build/steel-diver-sub-wars
