What was the first hack you wrote?

I recall early 2000's when Starcraft was all the rage.
There were a type of hack called a no-cd loader(which is redudant now when Blizzard removed CD checks),
bit at the time there was no current no-cd hack for Starcraft since a recent patch.
After searching some forums which was unhelpful with my limited knowledge of debugging, i've found out starcraft used one DLL as diablo(of which i had a plethora of hacks like e.g.Soulburners editor)
I've searched the image loaded by starcraft for same string as a no-cd hack for diablo used(a single nop at one offset)
there many candidates and i crashed my starcraft copy several times before i found out a match, which was aligned to 16 bytes with same
offset as diablo one(but about several pages higher), so i've noted this and after another patch created the same hack much faster.
It was never published and plenty of No-cd hacks and loaders appeared after the patch anyway so i could download one at will, so i had no motivation to make another one. Blizzard eventually decided that was user-unfriendly to require ancient CDs to spin everyday and  removed the CD-check once and for all.

I do not understand your question. The game code runs in Blizzard's servers. It's a client-server architecture, which is not unusual in games. The difference is that you don't get the server code — even if you want to play solo, you must be connected to a game hosted by Blizzard. In order to defeat this protection, a significant portion of the game must be rewritten from scratch.
