Thanks, I found the config file. I was even able to add new patterns, as well as change the monitor it looks at by default.
FWIW, 1.99.3 shut down hard, and 1.5 and 1.5.1 couldn't get permissions for a port until I rebooted. After that, 1.5 and 1.5.1 were able to detect the running EroDungeons without an issue.
Thanks for your time!
