In 2014, The Hero scripter released his program, which converts the entire map (models and textures) from the PS2 version to the PC version of the game.
This is a PS2 PC card envelope. It includes converted IDE, IPL, DFF and TXD files of the PS2 version of the game. Vehicles and entry markers are replaced, the position of objects and vegetation is added/removed in accordance with PS2.
The downside is that there are bugs with transport textures, I recommend using a separate PS2 transport package.
