Solution: Make config/settings/fullscreen work.

[Amarant]

Since there seem to be so many posts about this issue, here is the solution.

Open regedit by searching for regedit.exe on vista/7/8 or use "run" and type regedit.

For 64 bits Windows:
Go into: HKEY_LOCAL_MACHINE\SOFTWARE\WoW6432Node\Microsoft\Windows\CurrentVersion\Uninstall

For 32 bits Windows:
Go into: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

Now, right klick the "uninstall" key (looks like a folder). Select New > Key, name this new key SEGA.
Then, right klick the "SEGA" key. Select New > Key. Name this new key Sonic Adventure DX.
Then, right klick the "Sonic Adventure DX" key. Select New > String Value. Name this new string value Sonic Adventure DX.
Then, double klick the string value "Sonic Adventure DX" which you just created. In the Enter Value field, enter 1, press Ok.

Why Steam fails to enter this automatically is beyond me. :O

Thank's Bro, that saved me. But i still have a problem with this game, i am traing to run the game in a pc with windows 8 pro, and when i try to run the game, he run's, but only the sound, the vídeo simple turn in a black screen.

edit: when i up-dated my windows for the 8.1 the game simple run perfect.
Thank's.

Are you looking on the registry? Everyone should have it.

How do you find out if you have 32 or 64 bit for windows vista?

Start > Right klick "Computer" > Properties, you should find the info at "System type: "

I just did all this (the regedit thing) and nothing's changed. My controls are still the same. All I want to do is change the controls a little. Change the S button (Jump) to the Space Bar.

Hmm, wierd, haven't actually changed any of the controls myself since i use an Xbox 360 controller, gonna have to take a look at how that works...

I'm using the keyboard although having a controller would be nice.

Same as in the other versions. If you have trouble finding regedit you can start it by pressing WindowsKey+R and type regedit
