[REQUEST; NES; GAME GENIE] Super Mario Bros.

I was surprised that such codes don't yet exist...

Coin multiplier: makes every coin worth 10 or more instead of 1.
Hided blocks are visible (not an X-Ray code from Tony H.)

Peace, friendship, bubble gum.

@nolberto82, I've added your codes since I've checked now and thread's author (@Lex) only posted the requests and then wasn't active on forums anymore (last @Lex's activity date on his profile page was before you're posted your codes).
