How to copy HL2 via modding

So, I have a question. I tried to copy HL2 by modding it in SDK (2006), but it ended up making a mod of Episode 2. So I tried again, and Lost Coast. I don’t want to start up a new game on my original because I just want to play around with cheats, but it seems to be proving rather difficult. Can anyone help me?

Start a new game and delete the saves when you’re done then. That’s what I do.
All that extra time and effort seems pointless if you just want to play with cheats, they’re not gonna permanently fuck up your copy or anything.

What he said. You’ll save yourself lots of time and effort if you just backup your saves, do your playing around, then put them back later.

The cheats won’t affect anything except disable achievements, but those are re-enabled when you disable cheats.
