a few questions

1.iv been brousing around and i found these Steam linux binaries but i cant acsess them because that part of the repository has been blocked...where can i get these binaries (im asking for a download link)
2.i got some bugs with GTA SA and GTA Vice city...
a)GTA SA: the main character is going forward without me pressing "W" or any other key and i get some weard horizontal mirror effect that makes even the basic look of the game miserable
b)GTA Vice city: the same apples for Vice city only i dont get the mirror effect and i dont have sound

(some information that can help?)
