Yea, saw that earlier. It's neaaaaaaaaaat.

Oh, and 2p mode can be enabled by pressing B in level select. Pretty known already, but some may not know.

Here it is. The screen is not locked at the same point as in Sonic 1.

The egg capsule. It opens in the same way as in Sonic 1, differently from Simon's beta.

I don't understand how uncompiled code can end up in a compiled rom... any theories?

Debug stuff. Most of this stuff like labels n shiz are leftovers from a debug build, probably done so the debugger would display stuff? Or kinda like controlled program runs.

It's funny how a beta (or other similar builds) has that quite fancy cart label.

I'm fucking drooling on my keyboard when I play this. This is an awesome combination of extremely incomplete S2 and leftovers from S1. It's too bad so many levels wee not even created yet...and going into the Final Zone is cool too, how the game freezes with a purple screen when scrolled to a certain point. Probably because it calls for non-existant boss objects.

I also wonder why having Tails by your side fucks up sprites and collision.

It's not that uncommon. Look at Super Princess Peach or Lemmings for the PSP.

This cart label had me thinking... Now that we know that this build is very similar (if not exact same) to the Nick Arcade build, maybe it was why the label was a hologram?

I mean, Sega wouldn't bother sending a hologrammed proto cart (with a case!) to any magazine. That would suggest the Nick Arcade show...

Right guys, I gave a quick look at the ROM before I left earlier in the afternoon. Turns out that the music driver is more than just identical to Sonic 1's -- it's at the same exact offset in the ROM. Pretty bizarre, eh?

Anyway, if you want to hax the music, do it like you would Sonic 1. Not one byte is different, which is certainly interesting.

As for the findings so far - great job, guys! I find it awesome we can put aside all our drama bullshit for something that can benefit the community so much. Now I know why they called the finding the last beta the "golden age". :)

I'm gonna need volunteers to help maintain the main site, and update it with this new info. Any takers? If you're interested, state it in here, and PM me for FTP info so I can throw you the needed files to edit.
