To install this mod, you must have the game without any mods installed, 
a freshly installed version. Once you have it, go into the GTA Vice City Mobile Mod folder, 
copy everything inside, and paste it into your GTA Vice City folder. 
If it asks you to replace everything, say yes, and that's it. Now you can play and enjoy!

THAT'S ALL. I HOPE YOU ENJOY IT, AND SEE YOU IN THE NEXT MOD.
