POSSIBLE LEAK Sonic 2 Prototype? (FAKE)

[OdysseyNeptune]

I have come across a Sonic 2 Prototype, being a fan of this game i searched a lot about prototypes, and have found one that doesn't seem to be the Simon Wai Prototype, nor the later Beta 4.
Here are some screenshots of its level select.
On the left we have the Simon Wai Prototype, Beta 4 on the middle, and this prototype on the right, for comparison

The reason of why this prototype's screenshot is bigger is due to using an emulator, while the other 2 were screenshots from the Internet (i do have the ROMs for those other prototypes, but was lazy)
As you can see, both Beta 4 and the Simon Wai Prototype mislabelled Mystic Cave as Dust Hill, which is an entry in this prototype. Also note that Special Stage is simply Special here. In this prototype, there seems to be no Sky Chase nor Wing Fortress (Sky Fortress in Beta 4) which means that is earlier than Beta 4, but Mystic Cave being correctly labelled here is weird. "Dust Hill" seems to send to Genocide City from the Simon Wai Prototype, as both are empty slots with Chemical Plant's music. Also, Death Egg is still empty...
What do you guys think? I am going to upload the ROM if asked to.

Put it up for download and let the users take a look at it, if it's good we'll add it to the FTP. Thanks!

Where should i upload it?

[LilShootDawg]

Mediafire or MEGA.

Where did you find it?

You sure this isn't some sort of hack? There are LOTS of Sonic 2 Beta/Alpha/Prototype hacks around the web, a few of which have had attempts to pass off as real prototypes.

[OdysseyNeptune]

Found it on a link that now appears to be dead...
I am sure it isn't, it might be a build directly after the Simon Wai Prototype. I would call this Alpha 5 (with Simon Wai being Alpha 4 and Nick Arcade being Alpha 3, since there must be more prototypes)

I've played through it, and here are some differences:
Death egg music being played by getting 100 rings no longer occurs
Hidden Palace intro is quite different, most of the level is the same
Chemical Plant is much closer to Beta 4 than Simon Wai
Hill Top is much closer to Beta 4 than Simon Wai
Power sneaker sprite on monitors is inversed (not sure if this happens on Simon Wai too)
Green orb in Hill Top seesaws is now the flashing yellow and red thing

You should submit this ROM to Sonic Retro to see if they can find out if it's legit or a fake.

Yea that's sus.

[OdysseyNeptune]

sus? What does that mean? Suspicious?

[LilShootDawg]

Suspicious.

[OdysseyNeptune]

Hmm, but is there a way to verify if it is legitimate? Gameplay is almost the same as in the Simon Wai Prototype, however, Hidden Palace Act 2 has a correct spawnpoint and some layout.

[LilShootDawg]

I say it's fake. So don't upload it to the FTP.

[OdysseyNeptune]

It can be legitimate, but, if i upload it to the FTP, and it turns out it's fake, something bad happens? Not gonna upload for now cuz it might be risky

WOW, did not know about so much differences... It may be legitimate

That means nothing. You can make a fake and have MORE differences.

Let's disassemble it and see whether is it real or not. This way you (The OP) can be sure that it's safe to upload it to the FTP

[OdysseyNeptune]

Yes, but i do not know how

[LilShootDawg]

Let's disassemble it and see whether is it real or not. This way you (The OP) can be sure that it's safe to upload it to the FTP

That would prove nothing.

Why would that prove nothing?

There aren't a lot of builds for Sonic 2 that we have. And there are no logs or anything. You check for inconsistencies in the game code. You can't just open it in 7zip. You have to know and understand assembly. You have to know and understand how the code works for the Wai and Beta 4 builds. You have to look at this ROMs code and see if there is something that isn't in Wai or Beta 4.

[OdysseyNeptune]

I do not know assembly

[LilShootDawg]

It's fake. People from Sonic Retro have literally made a tool to detect hex-edited hacks. (Sorry about the pic.)

[OdysseyNeptune]

Well, fake. Good thing i didn't upload to the FTP. Guess i'll keep searching.
