Ah. I see, too bad. You should buy a 3d card. It's a really fun game, course, I've never played it before, this was my first time. It may be boring to other people that have played other 3d Sonic Games..

I got a file which went right up to $1FFFFFF, so you must have a duff download.

Anyway, analysis of it in a hex editor (since after the checksum is fixed it just gives me a black screen) seems to indicate it's exactly the same as the final.

 

I compared it to the final, and found spread data, either exclusive to LOst's or exclusive to the Final. I have a picture, but it's on my other computer...

The emulator must have deleted it after the decryption

 

Encryption key. I'm gonna go and try and figure that out. Hooray.

 

that don't work it asks for a login stuff

 

It works for me, but it's slow as... something really slow... since it's 2 600 MB files. I'm on the 3rd file, luckily, which is 54% done as of 8:00 PM.

Anywayz, I'm posting a *working* version of the Sega Smash Pack 2 Sonic 2 rom and my "findings", which aren't really findings at all. Here goes:

The *working* SSmash2 Sonic2 Rom!!


Here's the interesting parts:



The one on the left is my version, and the right, is the original from the cart. The clear parts, with the lines that connect to eachother, is data that is exactly the same. The yellow data is for the original rom ONLY, and the red data is for the Smash 2 rom ONLY. Data that is black with a line to the other rom, is relocated data.

The most interesting part of this, is that the rom I dumped, the smaller one, works flawlessly, even though there is 1 MB of data (seen in the yellow at the end of the original) missing! (Not sure, but maybe I added that excess data. I don't remember! )

EDIT: Okay, I *think* that that "extra" data you see on the end of my rom, is the HPZ excess data IPS thingy that so you can play HPZ in the final Sonic 2 rom. Interestingly enough, you notice that some of the added HPZ data from my original (modified :P) rom is present in the upper portion of the Sega Smash Pack 2 Sonic 2 Rom. (Don't quote me on any of this, unless, of course, I'm right :P)

Other than that, as you can see, it's EXACTLY like the final, just with a few pieces added or moved.

And sorry, no encryption key yet. Oh, and unless the Smash Pack 2 rom is compressed, the rom will never have that excess data at the end like the original rom.

Ummm... about that SADX: PC download... the files are in .mdf format. I've read that I have to use this thing called ISO buster to convert them to .bin format or something, but then how do I play the game?

 

Use Alcohol 120%

 

Never mind, I think I've almost got it working anyways using ISO Buster, but I'll have to burn a couple of CDs...

 

(Sorry about the double post) All right, I've installed the files and all that after burning the files to two CDs, but when I try to start it up, I get a message (in Japanese, although my computer tries to show it in English) and the only readable thing is "CD 2". I tried it with both CDs, too! :angry: :angry: :angry: :angry:
