So I am developing this Super Mario Bros clone, which looks exactly like Super Mario Bros for NES. I didn't change any graphics, they are ripped straight from the game using the emulator. I'm trying to copy exact behavior of the game, from the physics, to the maps. At this stage of development it looks like this (I took the screenshot from the my device):
And I am thinking of publishing it to the Google Play. This may be a stupid question, but I know I could get into some trouble, couldn't I?
I read on other sites that Nintendo seems to be pretty liberal in their treatment of derivative games. So could I get into trouble by publishing it to Google Play?
If so, then what could I do to minimize the risk of me getting into trouble? Maybe if change the color of mario, or change position of few pixels, it won't be considered mario anymore? Because I read somewhere that if you edit the copyrighted content just by a little bit (for example, changing the pitch of music) you can use it anywhere you want, is it true?
Thanks in advance.
