The best option for new maps and modes is to create a launcher that will automatically create / download folders and divide them into "ax files". Players who play on other servers would not have trouble with loading these folders. So, anyone who joins on AX with launcher / app can see maps and all the other modes that would have been created in gta folder.As for the GTA vice city map, it is possible to convert for GTA san andreas, it is not perfected but with some techniques can fix bugs. That was created my friend Correlli (ex samp beta tester).
