Sonic the Hedgehog (Japan) ROM

What else could be said about a game so classic that even started a competition between two of the biggest companies in video game history ever (and ended it as well!) regarding their mascot characters?
Sonic the Hedgehog is a 1991 classic video game for the 16-bit Sega video console, Megadrive/Genesis, were you fight in pure platforming plus speedrunning style against the evil madman Ivo Robotnik (named Eggman in Japan), who has abducted each small animal in the world and turned them into robots.
To help you in your quest you can gather Rings. Get one or two hundred of them, you get an extra life. Beyond that, they're useful as well: if you have one lone ring in your inventory you'll be invincible. Well, invincible minus if you don't get drowned, crushed or hit by spikes twice in a row, that is. You'll lose all your rings (in a huge explosion of rings) if you get hit, but you'll be still alive.
Sonic is a speedy fellow, and most of the first levels you'll just have to push right to run like mad through grassy hills, together with loop-de-loops and corkscrews, jumping around springs and enemies, but when that's over, real hardcore platforming starts. Sporting some of the most intrincate and notoriously difficult (if you don't know what to do or where to go) map layouts in the whole series, Sonic 1 is sure to have you on the tip of your chair.
In total, you'll face 6 zones, with 3 acts a piece, 6 special zones and a final showoff against Robotnik. Complete the game with the 6 chaos emeralds in your inventory (which you can gather by playing and finding them in the special zones), and call yourself a hero.
All in all, it's a special game, which opened up to a huge series of sequels and classic games.
This Japanese version of the game is exactly the same as the US/Europe one.
