You go to Level Editor. Then, you can choose what background you want, your size, even hack the game by editing the code.
You cannot turn into Super Sonic in Ultimate Flash Sonic, and there is no code that allows you to.
I think there is a misunderstander here.Google "super mario bros nes" to see what "Super Mario Bros." is actually.
You will probably need an action replay to do that. There is one code that lets you always have a Mega Mushroom. I'm sure there are probably other codes as well. You can buy action replays at places like Gamestop.

Yes, you can and here is how. First, look at the bottom left of your screen and press the Windows icon. Then, type in "Notepad" in the Search Bar. Afterwords, open up Super Mario Flash and make your stage. Then, save the stage by clicking the "CODE" button, and select it all. Then, copy/paste it on a notepad. Finally, go to file on the notepad in the Top right corner and say save. Then when you want to play your stage just open Notepad and copy/paste in on the load bar in Super Mario Flash. Now I don't need to tell you the rest.
