If anyone is looking for a more integrated version to do this, I've cracked the /release/client.exe to not check if a client is running and just continue with starting the client.
I've been testing for over a week now and so far I haven't come across anything that crashes the game due to this modification so I figured I'd share this with ya'll.
Replace the original <enb_dir>\release\client.exe with this one and then just start LaunchNet7.exe as usual.
(for the assembly code readers amongst us; I've simply changed a jnz instruction to a plain jmp prior to getting the messagebox)
