Due to the lack of anti-cheat possibility in SA-MP, Italy Mafia has it's own client which reads your GTA for illegal cheats/hacks before you can play.
You are not obliged to use the client; admins may however lock you out of the server if you are suspicious. You then may only play using the client to prove you're innocent.
You may as well use the client to connect faster. Once you loged in to the client, it will remember your login credentials. You will be automatically logged in ingame.
Download the client here, extract it to any place (e.g. your Desktop) and run it. Login, and start playing.
Once started, you will need to enter your in-game name and password. If you want to start playing, simply press the "launch" button. The client will now scan for any illegal mods/hacks in your GTA.
If any illegal mods/hacks are found, admins are notified and you will not be able to play. If there are no suspicious files, your game will start, you will connect to the server and you are automatically logged in.
No. We recommend you to use it every time you play on the server. If you connect with the launcher, admins are aware that your GTA copy does not contain any illegal cheats/hacks and that you're a legit player - and you're much faster off to login too!
