I run a few servers for the original Half-Life (CD Version) release, and it would be great if they could be supported by Gametracker especially since HLSW seems to be dead. I original submitted a thread like this requesting support for the "WON2" protocol, but that was incorrect because all WON2 does is just provide new master servers. So supporting this older protocol would avoid any legal troubles (if there were any at this time anyway). I believe this could provide some insight into the older protocol: https://github.com/multiplay/qstat/blob/a60436f061b0507fb4444e6eba76087dc5801544/qstat.c
