Was browsing some GTA forums and codenamevice.co.uk and came across a couple of fantastic "trainers" that add a tremendous amount of realism to the game (mainly driving the cars) IMO.
I just thought I'd detail a couple of them, so you lot can have a play
Firstly, we have the "Analogic Mapper". Do you own a joystick or gamepad with an analog D pad (The harder you press it, the faster/more things happen, you know the things )? Well if you download this you can bind the up, down, etc directions on your D pad to accelerate, steer, brake with varying power. It's excellent if you wish to drive slowly in built up areas of vice city without ruining your precious Porsche...I mean Comet Download it and have a play, and read the readme if you get stuck.
Secondly I found the "Vice City Camera Hack Tool" which gives you a cockpit view of the car so you can see the windscreen, bonnet, etc, again for the added realism of driving a car. It actually feels a lot more real too, jumps, crashes, etc, feel more realistic! Get it from here and read the readme for help!
You need to be a member of codenamevice.co.uk to be able to download, but registering doesn't take long!!
