S2B/Sonic 2 Beta Zones/Prototype B/Emerald Hill Zone As with Simon Wai's prototype, Emerald Hill is the most complete Zone in the ROM. It's the only one that can actually be completed, and it's the only zone with a boss. (Of course, we're not counting Green Hill Zone.) Act 1 The first thing you notice when you play this zone (by pressing start or by selecting it from the level select) is that Tails is missing. Emerald Hill is the only zone in the ROM that does this. If this is indeed the Nick Arcade prototype, Tails was likely disabled to prevent him from interfering with the 25 ring challenge. Different spinposts!   Emerald Hill Zone Act 1: Final Emerald Hill Zone Act 1: Prototype B While there are plenty of layout differences between this prototype later builds, the entire Act still feels very familiar. Note the similarity between prototype B's layout and the layout seen in the Nick Arcade video: Act 2 More of the same. This is one fundamental diffence in the layout, a spring takes you into one of the paths inside the wall. Interestingly (though not visible in this static image) is the circles in the background pulse quicker than in the later versions, this happens in Act 1 as well. Like in the later prototype, Robotnik comes straight down from the ceiling. However, unlike in the later prototype, he explodes when you beat him! In Simon Wai's version his wheels simply fly off without any explosions. Note, however, that the explosion graphics are from Sonic 1. It seems that at some point between Prototype B and Prototype A, the old explosion graphics were removed without being replaced with new ones. And thats the end of the playable part of the game! Emerald Hill Zone Act 2: Final Emerald Hill Zone Act 2: Prototype B Some minor differences dotted around this act, mostly in the middle.
