I know these DLLs, I have them, I think I got it from your old site (saw a post in reddit)
The problem is, there isn't the client.dll from March 2003 or earlier (the pack includes 1.5 client DLL)
That's why I'm asking patching the 1.6 client.dll to get it work with Famas and Galil sounds/slot/shield animations.
If you use 1.6 Game DLL and 1.5 Client DLL together it will work, but the buy menu will show 1.5 weapons only (but it will work like 1.6 menus) and Galil/Famas won't have sound/won't be selectable (unless you drop and take it again). When I look at the console (developer 2 activated) I see these messages when firing Galil or Famas:
Unknown event: events\galil.sc
Unknown event: events\famas.sc
Or something like that.

Counter-Life Beta 6's client.dll has the codes for Famas & Galil (as the mod was created for Half-Life it's weird all over place)

I can send the client.dll if you're interested. It's decrypted already.
