-more realistic handling for all cars

-more realistic handling for all bikes (limited by the stupid TLAD AI)

-more realistic flight model for all helicopters (limited by the stupid TBoGT AI)

-increased car deformation (150% available)

-has been tested with every single mission (TBoGT and TLAD included)

Improved vehicle spawning (optional):
The improved vehicle spawning adds vehicles to the traffic that dont spawn in the default game.
Now scooters (Faggio), Busses, SultanRS and Crossbikes (Sanchez) are driving around too.
Furthermore, the chance to encounter an Infernus, Comet, Banshee, Turismo, Coquette or SuperGT has been increased in some areas.
A map of those areas is included in this download. Who wants to spend 40 hours looking for his favorite car?

Improved weapons (optional):
The range of rifles has been changed to be more realistic, now you can take down helicopters that are more than 60m above of you.
Damage has been slightly increased, now it takes 4 instead of 5 shots to take down a cop.
M4 now does slightly less damage than AK47, but in return has its rate of fire increased from 430 to 500 rpm.

Compatibility:
This mod works with all GTA4 versions!

other mods:
works fine with other mods, unless the "handling.dat" files are being replaced/modified.

Custom car models:
This mod is for default models only, custom models require custom handling lines.

Installation:

BACKUP THE ORIGINAL "HANDLING.DAT" FILES FIRST!

GTA - Episodes from Liberty City (stand alone disk):

-copy "handling.dat"(6.44 kb) to "EFLC \ TBoGT \ common\ data"

-copy "handling.dat"(6.44 kb) to "GTA4 \ TBoGT \ common\ data"
-copy "handling.dat"(6.31 kb) to "GTA4 \ TLAD \ common\ data"

GTA 4 v1.070 without DLC:

This mod works with all GTA4 patches!

notes for GTA4 v1.060:
-you might need to delete the "filelist.pak" file
-you might need to run the filecheckfix.asi mod using an .asi loader

installation on GFWL DLC:
if you are missing "GTA4\TLAD" and "GTA4\TBoGT" folders,
then you have to move both required handling.dat files to this path instead:

Windows XP:
TLAD: C:\Documents and Settings\*USERNAME*\Local Settings\Application Data\Microsoft\XLive\DLC\5454083b\00000002\*TLAD folder*\content\common\data
TBoGT: C:\Documents and Settings\*USERNAME*\Local Settings\Application Data\Microsoft\XLive\DLC\5454083b\00000002\*TBoGT folder*\content\common\data

Vista/Windows 7:
TLAD: C:\Users\*USERNAME*\AppData\Local\Microsoft\XLive\DLC\5454083b\00000002\*TLAD folder*\content\common\data
TBoGT: C:\Users\*USERNAME*\AppData\Local\Microsoft\XLive\DLC\5454083b\00000002\*TBoGT folder*\Content\common\data

additional GTA4 tweaks (Improved Traffic / Improved Weapons):

in order to have improved traffic and weapons in GTA4, copy and paste "cargrp.dat", "vehicles.ide" and "weaponinfo.xml"
from the "additional files" folder to "GTA4 / common / data"

File info:

filelist.pak - contains default handling (and therefore needs to be modified)
handling.dat - defines car handling
-----------------------------------------------------
cargrp.dat - defines car spawning area (optional)
vehicles.ide - defines car spawning rate and appearance (optional)
-----------------------------------------------------
weaponinfo.xml - defines weapon properties (optional)

GTA4 game version overview:

patch 1: 1.010 (requires use of the "magic patcher" to make mods work)
patch 2: 1.020 (modified "filelist.pak" needed for mods to work)
patch 3: 1.030 (modified "filelist.pak" needed for mods to work)
patch 4: 1.040 (modified "filelist.pak" needed for mods to work)
patch 5: 1.004 (this version detects and prevents asi mods!)
patch 6: 1.060 (this version detects and prevents asi mods!)

Troubleshooting (GTA4):

Problem: game refuses to start (GTA IV 1.00 - 1.01)
Answer: make sure you have properly used the "magic patcher" to enable mods.

Problem: game refuses to start (GTA IV 1.02)
Answer: make sure you have properly replaced the file "filelist.pak" with the modified version.

Problem: game refuses to start (GTA IV 1.03 - 1.04/1.004)
Answer: launch R* social club software, click logout, then under username/password click "skip login",
then start the game. close the game. reboot. then login at R* club again and start the game.
if the game still doesnt start, download an asi loader and use it to load the "filecheckfix" mod.
That will enable mods in singleplayer.

Problem: handling of vehicles doesn't change (GTA IV 1.03 - 1.04/1.004)
Answer: make sure you have properly replaced the file "filelist.pak" with the modified version.
if it still doesnt work, download an asi loader and use it to load the "filecheckfix" mod.
That will enable mods in singleplayer.
