On Christmas '96, I was given a weird cartridge as a gift from one of
my friends. It's a weird Sonic 2 Cartridge that's a "prototype". I was
able to dump it and play the game on KGen. I gotta say, this is very
strange. Let's get into this.
Ok, to start, here's some context. Since Sonic 1 was a smash hit,
everyone wanted a sequel. In summer of 1992 at a toy show, a Sonic 2
cartridge was playing. However, it was stolen and made into Chinese
bootleg cartridges. I bet some kid had one of these as their only sonic
2 and was dissapointed that the game only had 4 zones and the last was
the easiest for some reason. I feel a bit bad for him.

Neo Green Hill Zone
It all starts off with the title screen. It's noticably different from
the final. The emblem itself was used in the Game gear Sonic 2, the
background is Emerald Hill's (which is called Green Hill btw), and the
copyright uses Sonic 1's font.
Ok
so this is Neo Green Hill Zone (Aquatic Ruin in the final), Sonic's
sprites look a whole lot like Sonic 1's sprites for some reason.
Tails' sprites are a bit different as well. There is no shine on his roll/jump sprites.
There is no act clear jingle. Also, tails doesn't fly back to you
when he dies, he just falls out of the sky while in his roll sprite.
Sonic's skid animation is like in Sonic 1, but with before and after frames. Strange, but I kind of like it.
The spring animation fixes an error in Sonic 1. In Sonic 1's spring animation, the shoe sprite doesn't have the white stripe.
I guess Neo Green Hill Zone just doesn't have a boss. Okay.
(I get that this is an early proto. Alright?)
