Ok. Found it out:
Find a picture you want:
Restrictions:
320x240 256 colors BMP. Name it Logo.bmp
Next Get qlumpy which was included in the HL SDK SDK/Texture Wad Tools. Then get cached.ls (Note it's LS). That's a script for qlumpy and can be found in SDK/SHELL. Now it's get a bit buggy. qlumpy is an old dos program and it caused trouble on my XP Professional.
But run Command prompt and you'll be fine.
Place both cached.ls and qlumpy on C:
Create the following folder system: C:quivermoddirgfxshell and place the logo.bmp there in shell.
Create the folder C:moddir and place a already existing cached.wad
there because qlumpy can't create wads!!! Copy Hl's or create a new one with Wally.
How to make folders? Right-click on empty space inside a drive (ex. C:)
and select New/folder and rename it.
Use command prompt and write:
C:qlumpy cached.ls
Then get the Wad in moddir and put it in the mod directory of your choice.
Wasn't so hard?
Still problems? E-mail me and I'll help.
