[quote:a49c338a7d="hedgehog2489"]I think is some pirate version or hack, since there appear a blooper out of water, which is very common in funny hacks.

Long time ago I found a Russian Site from someone called CaH4e3 who likes to dump and research Chinese Pirate Famicom cartridge roms. He released an interesting one, a NES version of Super Mario World.

I think it's a very well made pirate version, since Chinese do currently develop new games for Famicom chinese made consoles called often as Polystation, Gamestation, even 'Wii 360', etc.

However could it be a NES prototype? Because:
-&gt; When you press start it takes you to the warp zone, so you can jump to any world. (A debug mode)
-&gt; If you don't press start and watch the animation, it puts a black screen saying "(c) 1995 COPYRIGHT", would that was "(c) ???? NINTENDO".

In my opinion it's pirate, the score bar change it's color according to the level, looking crappy, but it's still a very well made work. I think you can have fun with it.

It would be nice if drx could say if it's homebrew or proto.[/quote:a49c338a7d]

strange when I press start it just starts the game no warp zones.
when I watch the vid it don't go to a black screen.

also "game over is glitced and says "game O#er"

the M in "Mario" as a nick on it too.

also the hax you dirrected me to don't work they seem as if they are bad rom dumps.
