SuperBoy is Ristar on the game gear, only 1000 times worse.

everyone knows that if you try to copy super mario bros. then it would super crapy

What are you trying to say anyways? That SMB is a piece of crap? I dunno what your trying to say but that's sure what it sounds like from the title of this thread.

I'm just saying that Super Boy is terrible.

Super Boy is a terrible game but SMB is EPIC. It started Nintendo.

The only good remake of Super Mario Bros is Super Mario Bros Crossover:

I've played Super Boy before. I hated it, so I quit playing it.

What do you expect from a unlicensed ripoff?

DarthDub : I expect 3D surreal graphics with realistic voice acting...

No, really, I gotta try this game to see how crappy it is. Because it sounds... well, crappy.

the_casualty : I'll try this game too tomorrow.

oh my god you dont want to try this game its so horrible

Ah, so this is one of those infamous pirated games I used to hear about. Jeez...it really makes you wonder where and when these "games" were made..

BNuge : That link you posted there, I clicked it and went to WORLD 7-4!

I found this game to be VERY entertaining.  For all the wrong reasons, as with these games so often.  For example, after Mario *AHEM* I mean Super Boy jumps, he stops for a split second, and floats up a little more.  Also, when correctly done, you can do a sort of double jump.  After the initial bounce given by jumping on an enemy's head, you can jump again.  Just entertaining for the way it looks.
Also, for some inexplicable reason, they made Mario Pink.
PINK MARIO!

He handles just as well as ice skates that have been greased up and are on the worlds slipperiest ice while also navigating an oil spill.  BUT WORSE.
They remove the power ups, and the one-ups as well, making this game a good challenge!
In 2 words:
Hilariously Awful.
Super Boy, GO!  JOIN THE RANKS OF BIG RIGS AND THE TOWN WITH NO NAME, AND CLAIM ETERNAL FAME/OBSCURITY AT THE SAME TIME!
I give this game 10/10
Graphics 2/10 (an extra point given for PINK MARIO ) 
Control -9000/10
Story 9/10 (Pink Mario has to go right and slide down all the flagpoles LIKE A BOSS, the end.  Wow.)
Fun Factor 10000/10 (Bonus points for the floaty jump, the double jump, and PINK MARIO )
Fun/Awful Fact: Click on MSX, and this game appears on THE FIRST PAGE.  Also, this game was apparently so incredibly popular that they made not one, but TWO sequels:  At the time of writing, Super Boy 3 shares the main page with the legendary original.
Good night, and
PINK MARIO!

BNuge : Oh yeah, Super Mario Crossover is the best copy of Super Mario Bros.!

Eversion72 : Wow, that game is bad! But, if you think that game is bad, try Super Bioman 4 for the MSX !!!

Super Boy is actually so impossibly amazing that most people see it in the form of a mediocre rip-off of Super Mario Brothers.  Through intense training, I have found it in it's true form; a game where you ride a robotic unicorn covered in machine guns and bazookas around the flaming desert trying to gun down as many demonic Superman clones as you can before they get you.  The reason for the double jump is because when you kick an enemy to death, you can steal it's soul through your foot and double jump.  The reason for Pink Mario  is the flames everywhere, just barely showing on the character.  The reason the enemies descend through the floor is that they descend from a flaming rainbow bridge that has been captured (you can reclaim it for bonus points) and used to get to lower areas by enemies.  And the reason for there being only four worlds is that the other four were so awesome, they were banned from the universe.
I just blew your mind, didn't I?
