I've been using this SDK https://www.moddb.com/downloads/half-life-sdk-v23-for-visual-studio-2008
to make a Half-Life Mod. So far, all i've done is add a new weapon, ammo type, and remove the MP5 grenades.
It all works fine, except that the game crashes without an error whenever I use impulse 101
in the console.
And yes, I do have sv_cheats set to 1.
Help would be appreciated.
