This is my attempt to have a ALMOST full version without downloading the full 1000 MB iso.

Theories or things that are known:
1) Geo data is stored in executable.
All I did was get the cracked 50 MB exe and that's solved.
2) SADX crashes on missing files.
So, if the game doesn't find ***.pvm, it will crash.
3) Garbage files will trick the game.
Making a copy of an existing file and renaming it to the missing file will trick SADX.

Here is a pic of how much I got up to:
http://oxygen-x.net/tux/w00t.jpg - File manager
http://oxygen-x.net/tux/w00t1.jpg - Menu screen
http://oxygen-x.net/tux/w00t2.jpg << player select screen is normal

All you need to do this is the cracked .exe (no-cd)
The 10 dlls that come with the game.

re-us.mpg (Missing movie, make a null file, and it will still work)
MOBILE1_BANK01.dat (missing sound)
.dat (missing sound, use DOS to make this one)

Missing textures:
AVA_GTITLE0_E.PVM
AVA_GTITLE0.PVM
ava_square.pvm
AVA_FSDLG.PVM
AVA_EMBLEM.PVM
AVA_VMSSEL.PVM
AVA_FILESEL.PVM
ava_stnam.pvm
AVA_SAN.PVM

//I am gonnah add them all when I give up, or finish

Basicly, I ended up downloading 50 MB for the demo, 25 MB for the zipped cracked exe, and 15 MB for 10 the missing DLLs.

I am gonnah see how far I can get.

Also, rename Sonicteam.pvm to sonicteam_e.pvm.
They removed the _e in the demos.

Interesting.... This would be very helpful to me. As I cannot buy the game, and I'm having a very hard time downloading the ISOs on my 56k....

I'm warning everyone ahead of time the quality loss you will get like this. The game will be basically useful only for hackers, as anyone playing will be like "WTF" However, if you want a trippy experience, this is the way to go.

I tried to play sonic, and it crashes. Hmmm.
(BTW, the real reason I am doing this is to figure if the game geo data is in the sonic.exe)
I wasn't keeping an eye on the debugger, but I'll try to see what went wrong.
If the map loads those _STG.rel files externally, I think we will figure it out by doing this test.

Its probley the only way I'm ever going to beable to play it.... I've had BitTorrent running for the past 4 hours and I've only gotten 2MB..... = /

I actually find it even more fun playing this on my keyboard than on my GCN. I don't know why, but I love playing games on a keyboard.

Guys, I don't mean playing it on the pc will be low quality, I mean playing it with the really small version we are making will be weird. Think LSD trip weird.

I think I found the problem. I had missed a texture:
T_STATIONSQUARE.PVR
It just flew by in the debugger.
I am gonnah try it now...

Strange, it reads all the files, and then the level appears.
The level is just blue and nothing there.
There is not even sonic on screen.
It then just crashes.

The only levels that work 100% are the ones that came with the demo.
The other levels just crash.
Strange. I used the debugger to see all the files that were needed. All files were made, but when the level name dissappears, it just crashes.

hmm.. maybe it has trouble handeling the packed textures...... have you made them so that they contain the same entries but no data..... within them?

My friend is sending me the missing textures.
I also sent him a program which will assemble how the hacked up game files look.

I made all the files the game needs, in the end it crashes for an unknown reason.
I am gonnah slowly replace the dummy files with the real textures to see what's jamming it.

I currently found that SOME textures must have a specific size to work or the game will crash. I am beginning to think this might be so with the PVMs.
I do know that this is true with PVRs.

The purpose of this attempt is not actually to make a cut down versionn of the game, but to actually try to understand the engine and file formats associated to it.

If I am right, all that is TRULY needed to play the game is 100 MB for the PVMs (430 mb unzipped) + 25 MB for the no-cd exe (50 MB unzipped) + like 5 MB for the PVRs and BIN files
That's 130 MB of how much you really need to have to get the game to run.
(That number may change after I test out if the textures my friend is sending do make it work)
The movies can be null files. And the sound is not needed to work.

Right now, the levels just crash for some reason. The only levels that do play are the ones in the demo.

You got to know that isos are uncompressed. So, if the above was an iso, you would have to get around 485 MB instead. They could rar the file if they were nice though.

Download the whole game here:

http://dwerkz.6x.to/Dredwerkz

Go to the gamez section. You need antileech and when downloaded the files need to be opened in WinZip.

It is approx 200MB.

I just installed using the file there, but almost all the songs are Emerald Coast 1! Did I install something wrong?

No, thats to save space.

I hope I am not hogging up this thread, but one last question, is there a way to get the autorun program to work on the no cd version, I need to run the game in windowed mode but the Autorun program doesn't work. Either I need it to work or I need an ini file to edit to open it in windowed mode(So I can use that memory editor, the main reason I downloaded the PC version of this game and am leeching off this thread for info to get it working)

1) Open up notepad
2) Put this in there:
[sonicDX]
framerate=1
fogemulation=0
sound3d=1
screensize=4
cliplevel=1
sevoice=1
bgm=1
screen=0
cmd0=3
cmd1=2
cmd2=258
mousemode=0
bgmv=100
voicev=100
language=0
padconfig=pad_user
[pad_user]
buttons=9
pad0=2
pad1=1
pad2=5
pad3=10
pad4=9
pad5=4
pad6=17
pad7=16
pad8=3

3) Save it in the directory where sonic.exe is as: "SonicDX.ini"

Where do I get the myt-sadx.c00 and .c01 file? It wont let me finish the install without it.

Mine worked as long as I downloaded every single file.

wierd o well I'll just re download it later maybe something got fucked up when i turned my firewall back on.

I'm pretty sure that is the BSOD from the Dreamcast version. If you die on Emerald Coast as Tails before the frist checkpoint you come to a completely blue screen. Even when you go back to Station square it is still blue. How blue is the screen? If it's a pretty light blue then i guess i'm right.

Thanks to Dude, it was figured that the game did that because of this:
Let' say you have a texture pack that is 100 kb and contains 10 textures.
If you replace it with a 10 kb texture pack that contains only 1 texture, this is what will happen:
1) Game loads the dummy texture pack
2) Game attempts texture #5 in the pack
3) Texture pack has only 1 texture in the pack
4) Memory is read out of range
5) Game is killed by Windows for trying to read memory not given to the program.

The blue screen is basicly the background color before any textures are applied.
When the game tries to read a texture, it then freezes->15 seconds later->crashes.
Hence, causing only the blue empty level to appear.

In the case of Emerald Coast, the blue is just the camera not resetting (camera locks position when player dies, then *should* go back to normal operation when the player respawns, but on EC, it stays put. When the game crashes because of a texture error, it crashes at load time, and doesn't even start to render anything at all.

thanks for the download but I have one problem. Did you have any problems with myt-32.sdx, myt-41.sdx, myt-46.sdx, myt-47.sdx, myt-48.sdx, myt-52.sdx, and
myt-56.sdx? The downloads worked fine but when I unziped the file it said "error [the location] unrecoverable zip file read error" should I just keep on retrying or what

EDIT: forget the problem above, I redownloaded the files and I got the game to play, thanks for the help :)

Try to redownload those files.

Did it ask you for a password?

the Dredwerkz site doesn't even show the fuck up for me. =P

Then download the Isos from BitTorrent. :P

where do i get the bittorent iso's

http://www.suprnova.org/ You'll also need the BitTorrent client from Here. :P

Is there anywhere I could download the music? (I'm on 56k >_<)

Sonic Adventure myth rip isnt on bittorrent though, only Deviance full iso. Dredwerkz always has troubles, since they have to re-upload stuff all the time.

Then download the Isos.... :P Their not that big.
