There is no gold star. there is a star for mkds and a cheat that lets the star stay the whole game.
Once you have the code on the action replay hit the green star at the bottom of the action replay home page and then check the ones you want by hitting the green star again. (go to codejunkies.com for more codes)
There is no code to play as Marx.

Get action replay while you have all 150 stars. Use the action replay code: CUSTOM LEVEL. Talk to one of the Toads. He will give you a star!!!

To use the codes you must have an Action Replay DS. Action Replays cost $20 at just about any place that sells video games(such as gamestop.) You open the Action Replay code manager which is on a disc that comes with the Action Replay. Open the codelist you wish to add the code to and right click on the game the code is for. Select "add new code" and a box will appear with a place for the code title and a place for the code. Copy and paste the code in and press ok. Once you have the code entered put your action replay in your DS, turn it on, and attach the USB cable that came with the Action Replay to your computer and the action replay. Once it says the two are connected, drag your new code into the action replay and taa daa! you are done. Or you can click on the star Icon on the action replay, scroll till you find your game and enter the code manually. I had to do this because I lost my USB cord. I would recomend using the computer method because some of the codes are pages long.
