This mod turns your game to be as close as possible to original Playstation 2 release. It is NOT compatible with your save files so you have to start a new game. It changes map files, models, textures, etc.
To install: just open the .7z and extract everything into your game's directory.

If your game does not open, just change the resolution in scripts/widescreenfixes.ini to match yours.

Updated my mod to v1.1 with some minor tweaks and improvements!
