  • Mouse will not go beyond the game rect now, allowing to play the game on multimonitor setups without problems
  • More precise frame limiter, reducing lag spikes a bit when playing with Frame Limiter on
  • The game will not ask for a CD when all audio files are copied to the disk anymore
  • In 1.0, armour cheat is now TORTOISE – like in 1.1 and Steam versions
  • In 1.0, BOOOOORING cheat now works properly – like in 1.1 and Steam versions
  • Mouse sensitivity is now properly saved – like in 1.1 and Steam versions
  • Headlight coronas now display properly (as they do on PS2, XBOX and PC Steam versions) This headlight fix is probably the best one available, as it duplicates Steam EXE fix so NO bugs are present (like with other fixes, where headlights can be seen through the car etc.)
  • Purple Nines Glitch has been fixed
  • Game now performs a bit better on high FPS. It doesn’t freeze on fadeouts anymore, although it still has issues with car physics, gravity and sounds. Therefore it’s still recommended to play with Frame Limiter set to ON
  • Rhino spawned via a cheatcode doesn’t stay on map forever anymore
  • Blista now can be lifted by a car crusher crane – instead, now it cannot lift Coach
  • Shooting from M16 in 1st person mode now increments bullets fired stat properly (so you can’t score Accuracy to be more than 100%)
  • Wet road reflections render properly again (just like with Road Reflections Fix)
  • Reintroduced light glows under weapon/health/armour pickups, bribes, hidden packages and money pickups – they showed only on PS2 due to a bug in all PC versions
  • Trace (Destination) blip is now scaling to the resolution properly
  • Garages-related and rampages-related texts now scale to the resolution properly
  • All texts now have proper shadows (depending on chosen resolution, without the fix they’d appear thinner etc.)
  • Free resprays will not carry on a New Game now
  • Fixed ambulance and firetruck dispatch timers – they reset on New Game now
  • The game will not create more than 32 blips at once now – while this never happened in an unmodded game, it could have happened due to exploits and potentially corrupted the save
  • Car reflections are now displayed correctly on Steam version
