Super sprint mods exist yet they fail to work when CJ is either buff or fat, they don't work when you're swimming either... So I decided to make one! This will work anywhere as long as you're pressing the sprint button and sprinting. :D This also gives you infinite stamina (doesn't use infinite run flag to avoid corrupting saves).
How to install: Install CLEO and CLEO+ and put the CLEO folder in your GTA SA folder.
