How do you make a Pokeball into a Master Ball?

This is not possible unless you happen to find an Action Replay cheat, in which case you might as well just use the "spawn 999 Master Balls" cheat and save yourself some time. That code is insanely easy to find for all versions of the game.
There is NO other way to make a Pokeball into a Master Ball, no matter what imbecilic "updownB" kinds of "cheats" you've heard. There is, however, an equation you can use to calculate whether or not the Ball you're about to throw will catch the Pokemon you throw it at. Simply search for "catch rate wiki" and select either the Wikipedia or Bulbapedia article, and one should have it alongside an indepth explanation.
If you're not adept at math, this equation is not suggested.
