Tomb1Main

This is a dynamic library for the classic Tomb Raider I game (TombATI version). The purpose of the library is to reimplement all the routines performed by the game and enhance the gameplay with new options.

See the Tomb Raider Forums topic.

This project is inspired by Arsunt's TR2Main project.

Installing

Get a copy of the latest release from here and unpack the contents to your game directory. Make sure you overwrite existing files. Currently Tomb1Main requires you to have the TombATI patch v1.7 installed to work.

Configuring

To configure Tomb1Main, edit the Tomb1Main.json5 file in your text editor such as Notepad. All the configuration is explained in that file.

Not all options are turned on by default. Refer to Tomb1Main.json5 for details.
