when you go in the GTA SA folder there should be a file called GTA_SA(.exe) back it up. Paste the no cd crack file and when it asks you "do u wanna replace this with this one" click yes and then it should work.
Try this one: no
I typed some cheats and saved the game and now it is too fast. Even if i start a new game it is still fast. I couldnt find a chat to make it slower. I tried the slower gameplay but it wasnt that. any suggestions?
