Build over supply limit as Protoss or Zerg
To build over the supply limit of 200, have your Dark Archons mind control any protoss unit, and you can do this just as much as you want! To build over the 200 supply limit of the zerg simply have at least 8 drones and a whole lot of minerals. Next mutate them into a cheap building like a creep colony and rush back to your Hatchery ( Lair or Hive) and find any larvae and mutate it into the unit that you want and then while it is mutating stop the drones from finishing and ta-da! Sadly, there is no way to build over the 200 supply limit as Terran.
If you are playing as zerg, enter "radio free zerg" and zerg music will play. (This only works for zerg)

Play as the zerg and get 9 drones. Tell 1 of them to build an extractor, then build another drone. Cancel the extractor and you have 11 drones and 1 overlord.
Build units beyond the supply limit
During game play press enter and type "food for thought" then press enter again. You will be able to build units past your supply limit.
In order to play the bonus level 'Dark Origin', finish the Zerg Brood wars level 'The Reckoning' (level 8) within 25 minutes. This can easily be accomplished by using the invincibility cheat 'power overwhelming'.
If you are Zerg and you have a Queen and you're able to use the abilaty "Spawn Broodlings", than use it on an enemy non-mechanical ground unit and when the two broodlings come out of that unit, hit one of the broodlings with "Spawn Broodlings", and two Broodlings will come out of that Broodling. If you do this reapeatedly than you can have an army of them.
Instead of playing a custom scenario, go to multiplayer and do direct connect. create a game on team melle and put all the same races in your team. for each time you put your race in, it's an extra 200 supplies! his means you can have 100 carriers if you play 2 teams and all protoss!
Locate Burrowed Zergs
To locate burrowed Zergs,click on any of your units and move the green arrow cursor around the place you think is not safe. If your cursor turns red there are burrowed Zergs there.
Place Command Center Near Resources
First, Lift up your command center by pressing "L" after clicking it or by clicking the arrow pointing up.
Then make it land by pressing "L" again but before it lands, press "SHIFT + S". Hold it until the terran command center lands. After it reach the ground, press Right Click near the Resources. You will notice that the command center flies and lands automatically near the resources
If you click on a Protoss or Terran unit repeatedly (alternately, assign it a grouping and hold the key for that grouping), it will say acknowledge your command, then proceed to other-worldy humour. Some remarks are wry Blizzard commentary on Warcraft and their other past projects (like Diablo).
