I now have IVPbot and AMX running on my CS1.6 listenserver.
Of course there's that new bots won't buy weapons problem but all else is working perfectly. I'm using metamod 1.17 amx 0.9.6j and ivpbot 1.1.1

You don't need to edit the liblist.gam file anymore even though ivpbot tries to when it installs. Add -dll ivpbot\ivpbot.dll to your icon's target or to your lauch properties in steam - games - counterstrike. Your path in the icon's target will look similar to this..
\Steam\Steam.exe -applaunch 10 -dll ivpbot\ivpbot.dll


IF and that's a BIG IF, you installed ivpbot to the right place, it will work.
