How does this work? I guess a plugin? Do you need to run a client for this next to SA-MP to make it work, like the audio plugin?
Yeah, you need to download a program.
Also, in the latest version, it also supports modding melee.dat and surfinfo.dat. We made the katana a powerful weapon, enabled sprinting everywhere (area 51, some interiors, ..), and removed those annoying dust clouds that appear when you shoot some surfaces.
This is a demonstartion of a program that runs on the client
side; it makes it it possible for servers to have custom gta
data files. It's simple for the end-user: you download the
program and connect to a server. The program will check
if the server is registered to have custom data files, and
download those prior to joining the server.
Your game files will not be touched by this program,
and you don't need to make any modifications to them.
This is still under heavy development with closed testing,
a public release will come eventually.
