OMG I am so frustrated. I have followed all of this. I even went and reinstalled half-life from my old cd because "Dizzy Devil" said
No regular Serria Half-Life and the lateset patch before Steam.
I keep putting in dev_overview 1 and dev_overview 2 and get absolutely nothing. Yes, I am in open GL at 1024x768 and I have tried this in cs1.5, cs1.6, cz, and the old sierra hl with the hl1.1.1.0 update. What am I doing wrong??? I really really want an overview. I would even email the .map file to someone if they felt like they could get it done for me. Help, I'm starting to get desperate.
By the way I did run the map from the start>run> c:sierrahalf-lifehl.exe -dev +mapname and also tried it from the c:sierracounterstrikecstrike.exe -dev +mapname (neither worked) It loads my map but can't get the damn dev_overview 1 or 2 to do squat.
