Diablo 2 -No cd help

[socketboy]

Hi.
I just got diablo 2, and I wanted to play it woithout the cd, for lan games and such, so I came here(game copy world) to get a patch or whatever to make it possible.

I go and download- "Diablo 2 v1.05 (v1.0.5.0) [ALL] No-CD/Fixed EXE"
The instructions say "Install the game - Full Installation (~ 1.5 GB)."
"Apply the official Diablo 2 v1.05 Patch"
"Replace the original GAME.EXE executable with the one from the Patch Archive"
"Copy the following file from CD#2 (PLAY CD) to the game directory2MUSIC.MPQ "
and
"Play the game!"
I did the patch, and the D2Music.mpq to the game directory, but what does it mean "Replace the original GAME.EXE executable with the one from the Patch Archive"?
Do I replace the regular .exe with the patch .exe?
I downloaded a file from there that was called "diablo2nocd105.rar" what am I suposed to do with that?
