Super Mario Bros NES Game Genie Codes - Part 1

THESE WERE DONE WITH JNES ver 1.1.1.29 and Super Mario Bros. (Japan, USA).nes -- NOT ON A REAL NES AND GAME GENIE -- I was bored staying up all night so I decided to plug some random Game Genie codes into Super Mario Bros. Here are the codes in order of appearance: NLPTNG - Makes coin blocks split apart when you hit them, then return to normal. GPILNK - Some powerups are missing, others will fall from the top of the screen after you hit the block. Might make a full game run more interesting. LILNIP - Changes behaviors associated with Fiery Mario. GPINLK - Some enemies make a weird echoing sound when you jump on them. Seems to happen at random. As far as I know, these are all original codes as of July 12, 2013.
